Step 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.

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.
