INSTALL THE NANO-SIM CARD – OPTIONAL
1. Ensure the receiver is turned off.
2. Remove the cover on the bottom of the receiver to
access the SIM card slot.
3. Insert the Nano-SIM card.
4. Reattach the cover over the SIM card slot.
5. Activate the Nano-SIM card. Press , , .
Select LTE Modem. Enter the APN and enable.
2
CHARGE THE INTERNAL BATTERY
1. Connect the USB-C PD power adapter (P/N
121928-01) and cable (P/N 121920-01) to the
USB-C port on the receiver.
2. The receiver display shows the current charge
status.
3. It takes up to 5.5 hours to fully charge the battery.
When the R750 receiver with the UHF radio is
transmitting at 2 W, the battery lasts for about 4 hours
at room temperature.
Adding a USB-PD powerpack (30,000 mAh) to a fully charged internal battery provides about 13.9
hours of power.
TIP – Alternatively, use the Trimble power supply (P/N 107000) with a DB26 adapter (e.g. P/N 57168)
or a lemo cable with DC input (e.g. P/N 59044) to charge the internal battery.

ACTIVATE WARRANTIES, INSTALL OPTIONS AND RADIO SETTINGS, AND
UPDATE THE RECEIVER FIRMWARE
1. Install Trimble Installation Manager.
Go to www.trimble.com/installationmanager.
2. Connect the receiver to your computer using a
USB-C or serial cable.
3. Start Trimble Installation Manager.
4. Select the Receiver tab and click Connect.
For information on updating the receiver firmware, go

CONNECT THE GNSS ANTENNA
Connect the GNSS antenna cable (e.g. P/N 58957‑02)
to the TNC connector on the receiver back panel. Do
not overtighten.
5
CONNECT THE RADIO ANTENNA
Connect the UHF radio antenna (P/N 123588) or
external UHF antenna cable to the RP-TNC connector
on the receiver back panel. Do not overtighten.
NOTE – If you are using a standard polarity 450 MHz external UHF antenna cable, a reverse polarity
TNC adapter (P/N 119128) is required. Do not use an adapter with a standard polarity whip antenna (e.g.
P/N 44085‑60) as this could negatively affect the performance of the radio.

6
CONNECT THE ETHERNET CABLE
1. Connect a Trimble DB26 adapter with an RJ45
socket (e.g. P/N 57168), to the DB26 connector on
the receiver rear panel.
2. Connect an RJ45 cable to the socket on the DB26
adapter.
