2.4.2 External Power Supply
The receiver is connected to an external power supply through a lemo to RS232
cable, and make sure that the red alligator clip is connected to the positive of
external power supply, black one to negative. Over-voltage function cannot
protect your T300 PLUS receiver if reverse connection.

internal UHF in the RTK mode; therefore, we strongly suggest using external power (7-28 volt DC)
for the base station.
