Powering the Receiver with an
External Battery
The receiver can use an external power source if the internal batteries
have become discharged or as a supplemental power source. External
batteries allow you to continue using the receiver in case the internal
batteries become discharged.
To check the status of the internal batteries, view the BATT LED
or check the status using available Topcon software.
• Check the BATT LEDs for battery status.
– A green light indicates greater than 85% charge.
– An orange light indicates an intermediate charge.
– A red light indicates less than 15% charge.
• Do one of the following using PC-CDU:
– Click ConfigurationReceiver to view battery voltages on
the Receiver Configuration screen.
– Click HelpAbout to view battery voltages on the About
PC-CDU screen.
To connect the receiver to an external battery, use the receiver
power cable and the accessory battery (Figure 2-12).
1. Connect the two cables using the SAE connectors.
2. Plug the power cable into the receiver’s power port.
3. Attach the battery clip to the battery.
