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.
