■ Connecting to a battery
RWARNING!
• NEVER remove the fuse holders from the cable
connecting the transceiver to a power source, especially
a car battery.
• NEVER connect the transceiver directly to a 24 V battery.
NOTE:
• The transceiver may not receive well on some
frequencies when installed in a hybrid vehicle, or any
type of electric vehicle (fuel cell vehicle). This is because
vehicle's electric components, such as the inverter
system, generate a lot of electrical noise.
• DO NOT use a cigarette lighter socket as a power source
when operating in a vehicle. The plug may cause voltage
drops and ignition noise may be superimposed onto
transmit or receive audio.
• Use a rubber grommet when passing the DC power cable
through a metal plate to prevent a short circuit.
INSTALLATION AND CONNECTIONS
RWARNING!
• Make sure DC power cable polarity is correct.
Red: Positive + terminal
Black: Negative – terminal
