10
The G90 will operate best with a 13.8V external DC power supply with a continuous current load capacity of at least 10A. The supplied power cable
must be used to connect the radio to the DC power source.
Please note the polarity of the wiring before connecting your radio to a power source. Reversing the polarity can cause damage to the transceiver
that will not be covered under warranty.
The red wire is connected to the positive terminal of the power supply, and the black wire is connected to the negative terminal.
When using an external power supply, a ferrite ring can be fitted to the power supply cable to help minimize external interference from entering the
radio, or to prevent RF from the radio being radiated via the power cable. The ferrite ring sho
uld be installed as close as possible to the radio’s power
socket.
