Introduction P110 Portable Radios

Introduction
Welcome To The Motorola Radius P110 Radio
The Radius P110 Portable Radio is a sophisticated state-
of-the-art unit. It incorporates the latest technology avail-
able in two-way radio communications.
The use of microcomputer technology makes changing
radio characteristics such as operating frequencies and
squelch codes both economical and fast. Any computer
equipped Radius dealer can easily reprogram your radio's
operating characteristics, or your radio can be “cloned” from
a radio already programmed to your desired frequencies
and codes.
The P110 radio meets tough environmental demands while
providing cost effective and reliable communications. It
meets the U.S. Government Military Standards 810C, D
and E for low pressure, high temperature, low temperature,
temperature shock, solar radiation, rain, humidity, salt fog,
dust, vibration, and shock. The P110 radio also meets the
Electronic Industry Association RS316B electrical and
mechanical specifications. The Motorola Accelerated Life
Test (ALT) assures that possible failures brought on by field
stress and abuse are identified and designed out of your
radio before it reaches your hands.
All of these features provide for better, yet more cost effec-
tive communications for you.

Alert Tone Indicators P110 Portable Radios

Alert Tone Indicators

Power-Up

Each time the radio is turned on, a microcomputer and syn-

thesizer self-test occurs. A high pitched alert tone is gener-
ated for approximately 1/8 second to indicate that the
microcomputer and synthesizer are functioning properly. A
second low pitched tone is generated if the start-up test is
not successful.

Transmit on Blank or Receive-

Only Channels

Pressing the PTT button while

tuned to a blank or “receive-
only” channel causes an alert
tone. The tone continues as
long as the PTT button is
depressed. The radio transmit-
ter is not enabled.

Transmit Inhibition Busy Channel with Busy Channel

Lockout

Pressing the PTT button during a “busy channel” condition

(other than your PL/DPL group) generates a continuous
busy tone that lasts as long as the button is depressed.

Time-Out Timer

The time-out timer limits the

amount of transmission time
to a preset length (off, 30 or
60 seconds). At the end of
this time an alert tone indi-
cates that your transmission
has been cut off. The alert
will continue as long as the
PTT switch is depressed.

Operation P110 Portable Radios

Operation
To Power-Up
Rotate the volume control 1/2 turn clock-
wise to turn on the radio. A power-up
alert tone is generated for approximately
1/8 second to indicate that the radio has
passed a self-test of the microcomputer.

NOTE
If the short power-up alert tone is not gener-
ated, or if a second low alert tone is generated
(indicating corrupted radio programming), turn
the radio off, check the battery (charge or
replace if necessary), and turn the radio back
on again. If the power-up alert tone is still not
generated, a fault exists in the radio. Contact
your local Motorola Radius dealer.

To Receive
1. Set the channel selector to the
desired channel position.

2. Listen for a transmission and adjust the volume control

to a comfortable listening level. If no transmission is
heard, depress and hold the volume control button to
unsquelch the radio and adjust the volume to a com-
fortable listening level.

3. The radio is now set to receive all calls on the selected

frequency.

4. If you wish to monitor a channel (disable PL/DPL) press

the side mounted control button. If programmed as a
Monitor Button, the LED glows yellow for 4 seconds to
confirm that the coded squelch is disabled. Any time
the PTT button is pressed when the P110 is in the mon-
itor mode (disable PL/DPL), the LED temporarily glows
yellow to remind you that this state is active. The radio
remains in the monitor mode until the control button is
pressed again, to reverse the state.

5. If programmed as a Volume Set Button (manual moni-

tor), the radio has the ability to monitor until the button
is released. While pressed, a “rushing noise” will be
present which indicates the current level setting of the
volume control.

NOTE
All P110 radio models have an internal squelch
setting which is adjusted at the factory. The
squelch level setting is not a user-operated con-
trol; however, it may be reprogrammed using
the Radio Service Software available at your
local Motorola Radius dealer.

To Transmit
1. Set the channel selector to the desired channel position.

2. Do not interrupt another user. Listen for activity on your

channel. If the channel on which you are transmitting is
programmed to receive PL/DPL, momentarily depress
the control button to listen for channel activity. The
channel must be clear before transmitting.

3. While holding the radio in a vertical position with the

speaker-microphone grille two to three inches from
your mouth, press the PTT button on the side of the
radio and speak slowly and clearly into the grille area.
When finished transmitting, release the PTT button to
receive. When the PTT button is depressed, the LED
glows red and remains on for the entire length of the
transmission, and turns off when the PTT button is
released.

NOTE
When the PTT button is depressed (and as long
as the PTT button remains depressed), The
battery voltage is automatically monitored and if
the voltage is low, the LED flashes red to alert
you of the low battery condition. In addition, a
double alert tone is sounded when the PTT but-
ton is released.

Operation with Standard Features P110 Portable Radios

Operation with Standard Features

To fit your particular needs, a number of features are avail-
able to enhance the operation of your P110 radio. These
capability features are described for you in this section.
Time-Out Timer
The Time-Out Timer (T.O.T) feature alerts you if the trans-
mitter is keyed for a long period. This feature prevents chan-
nel tie-up and excess battery drain in case of an inadvertent
keying of the transmitter. The radio operates normally in the
receive mode with the T.O.T. feature. However, in the trans-
mit mode, a single transmission (uninterrupted depression
of the PTT button) “times-out” after 30 or 60 seconds and
the radio reverts back to the receive mode, even with the
PTT button remaining depressed. After the 30 or 60 second
time out, a continuous alert tone is generated in the receive
mode until the PTT button is released.
Volume Set
When programmed as a Vol-
ume Set button, the Control
button will initiate the volume
set feature. This gives the
radio the ability to monitor the
current radio volume level
whenever this button is
pressed. A “rushing noise” is
present for the duration of the
button press that indicates the
current level setting of the vol-
ume control.

P110 Portable Radios Operation with Standard Features

Busy Channel Lockout

Busy Channel Lockout is a privacy feature that prevents the
radio from listening to or transmitting over conversations
outside its talkgroup, keeping lines of communication clear.
Whenever the radio is not allowed to talk, you will hear busy
tone if you attempt to transmit. The radio will be allowed to
transmit:
1. when the channel is clear
2. during the group's repeater hang time, until a carrier
drop is seen
3. when receiving transmissions from your own group
(Common PL/DPL code).
Whenever a channel is programmed for PL/DPL busy chan-
nel lockout, pressing the Control button does not put the
radio into the carrier squelch mode. This means that the
radios with PL/DPL busy channel lockout programmed can-
not monitor or listen to the other groups' transmissions. Fur-
thermore, the volume set function is also disabled on any
channel that is preprogrammed as a PL/DPL busy channel
lockout channel.
On carrier squelch channels, Transmit Inhibit is available to
prohibit transmissions when any carrier is present.

P110 Portable Radios Optional Enhancements

Optional Enhancements
(Not Available on 2 Channel Models)
Channel Scan
This optional feature allows you to monitor a number of chan-
nels. The receiver checks each channel in a preprogrammed
list for activity (up to 7 channels on the 8 channel model).
Two types of channel scan are offered in the P110; non-prior-
ity and priority scan. Both types of channel scan are available
with PL/DPL operation. To initiate the scan feature, rotate the
channel selector switch to the channel in which scan is pro-
grammed. If a conversation is initiated on any of the channels
that the radio is scanning, the radio stops on the active chan-
nel and you can listen to the conversation.
NOTE
The P110 scan list is not operator selectable;
however, it may be reprogrammed through the
Radio Service Software available at your local
Motorola Radius dealer.
• Non Priority Channel Scan
With this type of scan operation, no one scan channel has pri-
ority over another. The scanner stops on the first scan channel
with activity, and when the activity is over and a 3-second
"hang-time" has expired, proceeds to the next scan channel.
• Priority Channel Scan
Any one of the radio's programmed channels may be desig-
nated as the priority channel. Whenever activity occurs on
the priority channel, the scanner automatically stops there
and the priority alert tone is heard. Even if you are listening
to another channel in the scan list, the radio automatically
goes to the priority channel when there is activity.
• PL/DPL Channel Scan
Private-Line operation is offered with priority and non-
priority channel scan. With this mode of scanning opera-
tion, the scanner stops on only the scan channels coded
with the proper PL/DPL tone if PL/DPL signalling is active
when you initiate scan.
NOTE
If the monitor mode is not active when the scan-
ning feature is initiated, the radio performs a PL
type of scan. If the monitor mode is active when
the scanning feature is initiated, the radio per-
forms a CSQ type of scan.

Optional Enhancements P110 Portable Radios

• Talkback Scan
This is an option of the channel scan features listed on
page 19 that is used when the PTT button is pressed
when scanning has stopped on a channel. When transmit
or receive activity ceases on a scan channel, a "hang
time" of approximately 3 seconds occurs prior to the radio
resuming scan for other channel activity. This "hang time"
gives you time to receive or respond to a call before scan-
ning resumes. The "hang-time" is programmable through
the Radio Service Software available at your local
Motorola Radius Dealer.
• Designated Channel Scan (Home Revert)
Pressing the PTT button while the radio is scanning
causes the radio to transmit on the preprogrammed desig-
nated channel location. This channel location is program-
mable through the Radio Service Software available at
your local Motorola Radius Dealer.
NOTE
If both Designated Channel Scan and Talkback
Scan are selected, the radio transmits on the active
channel. If however, there are no active channels,
the radio transmits on the Designated Channel.
• Scan Talkback Tone
The Scan Talkback Tone feature enables you to find the
last active channel received during scan mode. A beep is
emitted when the channel selector knob is rotated to the
last channel received during scan.
• Scan Nuisance Delete
When a conversation occurs and it is not your priority
channel or designated scan channel, you can temporarily
eliminate this channel from the
scan list by pressing the side
Control button (if the Control but-
ton is programmed for Scan Nui-
sance Delete). To add the deleted
channel back to the pre-pro-
grammed scan list, you must exit
and reenter the scan function.

NOTE
The Volume Set feature is replaced whenever
the side control button is programmed to oper-
ate the Scan Nuisance Delete feature.

P110 Portable Radios Optional Enhancements

Signalling Enhancements
Quik-Call II Decoding
Call Alert
Call Alert works similarly to tone-only pagers. When a Call
Alert (page) is received, a series of 4 beep decode tones
are heard while the LED flashes yellow. The LED continues
flashing yellow and alert tone continues until the call alert is
acknowledged by the radio. If you transmit by pushing the
PTT button or change the rotary channel selector while a
Call Alert signal is in progress, the LED stops flashing and
the Call Alert tone is disabled.
Voice Selective Call
This feature operates like a standard pager providing a one-
time voice message. When a Voice Selective Call is
received by the radio, a one-time 2 beep decode tone is
heard while the LED flashes yellow. The radio unmutes and
the voice message is heard. The LED continues flashing
yellow while the voice message is heard. The Voice Selec-
tive Call feature does not require any action to acknowledge
the message and after the transmission is completed, the
radio returns to normal operation.

MDC-1200 Encoding
PTT ID
When on a channel with the PTT ID feature, the radio trans-
mits an identification code (unit ID) to the base station, indi-
cating which portable is in operation. This code is sent
whenever the PTT button is pressed. A sidetone is heard as
the ID is being transmitted; when the tone ends, start your
voice message in the standard manner. The LED glows red
during the time that the ID is sent out.

Signalling and Channel Scan

Signalling and channel scan are compatible in the P110
radio. However, during scan operation, a Voice Selective
Call on a particular channel could be missed since the radio
may not be checking that channel when the Voice Selective
Call is being sent.
It is recommended that priority scan be selected and the sig-
nalling channel be designated the priority channel to improve
the likelihood that the Voice Selective Call is received.

performance. The battery was
designed to be used only with a
Motorola P110 charger. Charg-
ing in non-Motorola equipment
may lead to battery damage and
void the battery warranty.

NOTE
When charging a battery that is attached to a
radio, always turn the radio off to ensure a full
charge.

Charging Temperature
The battery should be about 77° (room
temperature) whenever possible. Charging
a cold battery (below 50°F) may result in
leakage of electrolyte, and ultimately, in
failure of the battery. Charging a hot bat-
tery (about 95° F) results in reduced dis-
charge capacity, affecting the performance
of the radio. P110 rapid rate battery charg-
ers contain a temperature sensing circuit

to ensure that the battery is charged within these tempera-

ture limits. If the charger is not performing a rapid rate
charge, the charger’s LED flashes red to indicate that the
battery is being charged at a slow trickle rate. For additional
information on batteries and battery charging, refer to the
battery charger information in the service manual.
Short Circuit
Care should be taken to avoid external short-circuiting of
the battery.

CAUTION
A sustained high rate discharge (e.g., a paper
clip placed accidentally across the battery con-
tacts) may permanently damage the battery,
void the battery warranty, and create a burn or
fire hazard.

Memory Effect (Reduced Charge Capacity)

The Memory Effect was a phenomenon which caused a
temporary loss in battery capacity or voltage due to repeti-
tive shallow discharging or low term overcharging. This
Memory Effect has been virtually eliminated in Motorola
batteries with the use of the latest in cell technology from
our selected cell suppliers.
Nickel-Cadmium Battery Disposal
For disposition, Nickel-cadmium sealed rechargeable bat-
teries should be delivered to an authorized metals reclama-
tion dealer (refer to inside front cover of this manual).

WARNING
DO NOT DISPOSE OF ANY BATTERIES IN A
FIRE AS THEY MAY EXPLODE!

injury to persons.
• To reduce risk of damage to electric transformer and
cord, pull by the transformer rather than the cord when
disconnecting charger.
• Position cord so that it will not be stepped on, tripped
over, or otherwise subjected to damage or stress.
• An extension cord should not be used unless absolutely
necessary. Use of an improper extension cord could
result in a risk of fire and electric shock. If an extension
cord must be used make sure:
(1) That pins on plug of extension cord are the same
number, size and shape as those on transformer,
(2) That extension cord is properly wired and in good
condition, and

(3) The cord size is 18AWG for lengths of up to 100 feet,

and 16AWG for lengths up to 150 feet.
• Do not operate charger with damaged cord or plug —
replace them immediately.
• Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way; take it
to your local Motorola Radius technician.
• Do not disassemble charger; take it to your local Motorola
Radius dealer when service or repair is required. Incorrect
reassembly may result in risk of electric shock or fire.
• To reduce risk of electric shock, unplug charger from out-
let before attempting any maintenance or cleaning. Turn-
ing off controls will not reduce this risk.

To Operate Charger
1. Insert the battery, with or without the radio, into the
charger pocket. (Be sure that the radio is off).

2. Insert plug into the charger and plug the transformer

into the appropriate AC power outlet.

4a. For Single-Unit Standard Rate Battery Chargers only:

When a standard-charge battery reaches full charge,
no change in the LED occurs (red glow remains). The
battery fully charges in 10 hours.

NOTE
You can turn the radio on while it is in the
charger and have it receive normally. However,
allow at least 25% more time for the battery to
reach full capacity. DO NOT TRANSMIT WHILE
THE RADIO IS IN THE CHARGER.

4b. For Single-Unit and Multi-Unit Rapid-Charge Battery

Chargers only: When charging a rapid-charge battery,
the LED glows green indicating CHARGE COMPLETE
when the battery reaches full charge. This LED also
indicates that the battery is now charging at a trickle
rate. A LED flashes red indicating that the battery may
be out of “rapid charge range”. The rapid charge auto-
matically begins when the battery is within the correct
range. Typical charge times for Rapid-Charge Battery
Chargers are as follows:
60-90 Minutes for High Capacity Battery

NOTE
A new battery or one which has not been used
for several months may cause a premature fully
charged indication. These batteries should be
trickle charged overnight before putting them
into service.

5. If the LED does not glow red when the battery is

inserted into the charger, check the battery and charger
contacts to be sure they are clean. There are no user
serviceable parts in the charger. If the charger fails to
operate, contact your local Motorola Radius dealer.

ment. Proper operation of this radio will result in user expo-
sure substantially below the FCC recommended limits.
DO NOT hold the radio such
that the antenna is too close to,
or touching exposed parts of the
body, especially the face or eyes
while transmitting. The radio
performs best if the microphone
is two or three inches away from
the lips and the radio is vertical.
DO NOT hold the transmit (PTT) button on when not actu-
ally desiring to transmit.
DO NOT allow children to play with any radio equipment
containing a transmitter.
DO NOT operate a portable transmitter near unshielded
electrical blasting caps or in an explosive atmosphere
unless it is a type especially qualified for such use.
DO NOT operate the portable with a headset or other audio
accessories at high volume levels. Hearing experts advise
against continuous high volume operation. If you experi-
ence a ringing in your ears, reduce volume level or discon-
tinue use.
