CONNECTING WITH A REGULATED POWER SUPPLY
To connect the transceiver with an appropriate regulated
power supply, use an optional PG-2W DC cable.
1 Confirm that the power switches of both the
transceiver and power supply are OFF.
2 Connect the optional PG-2W DC cable to the power
supply; red lead to positive (+) terminal, and black
lead to negative (–) terminal.
3 Connect the barrel plug on the DC cable to the DC IN
jack on the side of the transceiver.
Note:
◆ Only use the power supplies recommended by your authorized
KENWOOD dealer.
◆ The supply voltage must be between 5.5 V and 16 V to prevent
damaging the transceiver. If input voltage exceeds approximately
18 V, warning beeps sound and a warning message appears.
