3.3 Powering Up
Note: The power up sequence must be performed in the order shown in this section (remote
transmitter FIRST, Display Clock SECOND) to avoid the Clock synchronization time out.
The Transmitter:
Version 1.4 ©Copyright 2018, Ambient LLC. All Rights Reserved. Page 5
1. Remove the battery door on the back of the transmitter and insert 2 new AA batteries,
according to the polarity information marked on the battery compartment, and replace the
battery door, as shown in Figure 2. Place the transmitter about 5 feet from the clock.
The Clock:
1. Plug the AC adaptor into the DC jack of the clock.
2. Remove the battery door on the bottom of the clock and insert 3 new AA batteries, according
to the polarity information marked on the battery compartment, and replace the battery door.
3. Once the batteries are inserted, all of the LCD segments will light up briefly before entering
the sensor search mode.
4. Once the wireless transmitter has synced up to the clock (can take up to 5 minutes), you can
place the sensor outside.
5. The clock will display 12:00am and will attempt to synchronize with the RCC at 12:05am.
The clock will automatically search for the time signal at 2:00, 8:00, 14:00 (2pm) and 20:00
(8pm).
Note: The clock will always display the color green when the clock is searching for
the radio controlled signal. The mono color green is best for avoiding wireless
interference from the display.
Note: If no display is present after powering up the clock, press the reset button on the back of the
clock with an open ended paper clip or sharp tool.
search icon will turn on. The RCC will continue to search for six minutes. It will try again
every two hours.
Figure 3
If the time is incorrect by increments of an hour, or does not change on your radio controlled clock
(RCC), please reference Section 7, Troubleshooting Guide.
Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although the
sensor is weatherproof, it is best to mount in a well-protected area, such as an eve. Do not place in
standing water or snow.
Wireless signals are impacted by distance, interference (other wireless devices, wireless phones,
wireless routers, TVs and computer monitors), and transmission barriers, such as walls. In general,
Version 1.4 ©Copyright 2018, Ambient LLC. All Rights Reserved. Page 6
wireless signals will not penetrate solid metal and earth (down a hill, for example).
The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction
decreases the transmission range by the factor shown below.

5.4 Barometric Pressure Display and Settings
5.4.1 Barometric Pressure Units of Measure
In normal time mode, press the BARO button to change barometric units of measure (hPa / inHg /
mmHg).
1. Press and hold the BARO button for 2 seconds to enter barometric mode. The icon BARO
will flash.
Make sure the REL Pressure is showing on the display. If ABS Pressure is showing, switch to
REL pressure per Section 5.4.2.
2. Press (do not hold) the BARO button again. The relative pressure will flash.
3. Press the +/CHANNEL to increase the relative pressure and -/MEM to decrease the relative
pressure.
4. Press (do not hold) the BARO button again to exit the relative pressure calibration mode, or
wait 60 seconds to time out.
Note: After calibration, the barograph will reset to 0 change (flat line across the graph).
To compare pressure conditions from one location to another, meteorologists correct pressure to
sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected
relative pressure (the pressure your location would be at if located at sea-level) is generally higher
than your measured absolute pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m), but
the relative pressure is 30.00 inHg (1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the average sea-level pressure
around the world. Relative pressure measurements greater than 29.92 inHg (1013 mb) are
considered high pressure and relative pressure measurements less than 29.92 inHg are considered low
pressure.
To determine the relative pressure for your location, locate an official reporting station near you (the
internet is the best source for real time barometer conditions, such as Weather.com or
Wunderground.com), and set your weather station to match the official reporting station.

5.5 The Forecast Icon
5.5.1 Principle of Forecasting based on Barometric Pressure
The weather forecast or pressure tendency is based on the rate of change of barometric pressure. In
general, when the pressure increases, the weather improves (sunny to partly cloudy) and when the
pressure decreases, the weather degrades (cloudy to rain).
The weather forecast is an estimation or generalization of weather changes in the next 12 to 36 hours,
and varies from location to location. The tendency is simply a tool for projecting weather conditions
and is never to be relied upon as an accurate method to predict the weather.

To automatically scroll through channels 1, 2, and 3, press and hold the UP button for 2 seconds (the
beep will sound). The wireless channels will scroll on the screen every 5 seconds.
If you lose synchronization from the remote wireless sensor for an extended period of time or you
replace the batteries in the wireless sensor, you may need to resync or reset the sensor to the console.
To resync the sensor(s), press the SENSOR button in the battery compartment and the sensor display
will show dashes (--.-). Wait several minutes for resynchronization.
To reset the console, disconnect from AC power and remove the batteries for 10 seconds, then reinsert
the batteries and reconnect AC power. Alternately, you can press the RESET button on the back of the
console. The sensor display will show dashes (--.-). Wait several minutes for resynchronization.

up. weather environments, install lithium batteries.
If the transmitter is not flashing, replace the
batteries.
Resync the console. Reference Section 5.15.
The maximum line of sight communication
range is 150’. Move the sensor closer to the
clock.
If the sensor assembly is too close (less than
5-10’), move the sensor away from the clock.
Make sure the remote sensors are not
transmitting through solid metal (acts as an RF
shield), or earth barrier (down a hill).
Move the clock away from electrical noise
generating devices, such as computers, TVs and
other wireless transmitters or receivers.
Move the remote sensor to a higher location.
Move the remote sensor to a closer location.
