Operation
Radio
The radio has a permanent 12-volt supply from pin 4 of the
voltage converter to pin 5 of the radio. The permanent
supply is to retain the memory in the radio.
The 12-volt switched supply to power the radio is fed from
pin 5 of the voltage converter to pin 2 of the radio via a
rocker switch (Mute button) in the right hand console of the
cab. Operating the mute button simply turns off the power
supply to the radio.
Cigar lighter
The cigar lighter/phone charger, is fed from the switched
feed only.
