PRECAUTIONS
• Never splice into the power lead to supply
other equipment with power.
• After installation and wiring, always check the normal
operation of other electrical equipment.
• Make sure that no wires interfere with driving
or getting in and out of the vehicle.
• Insulate all exposed wires to prevent short-circuiting or electric shock.
• Do not operate the unit for prolonged periods
with the engine off. Prolonged operation with the
engine turned off will drain the battery.
• To prevent accidents, keep the volume of your radio at a level
that allows you to hear outside noises such as emergency
sirens and train crossing warnings. Prolonged exposure
to high volume levels may also result in hearing loss.
• This unit requires 12 volts to both the red and yellow power leads.
The unit will not work without power to both of these leads.
• Disconnect the negative (-) battery cable before beginning
installation. Verify the battery ground by checking that one
wire is connected to the vehicle’s starter mounting bolt or
engine block and the other to the vehicle’s chassis using at
least 8 gauge wire. Make sure the alternator or generator
connections are secure and free from corrosion, rust or dirt.
• This unit is designed for operation with a negative ground
12 volt DC battery system. Do not operate this unit with
other battery systems, especially an 18 or 24 volt DC or a
positive ground system. If you have a 6 volt system, you
need to either convert to 12 volt DC or purchase a separate
inverter that would increase the voltage to 12 volts.
NOTE: The inverter needs to be rated at 10 amps or higher in order
for the radio to operate properly.
