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 entering/exiting
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.
• 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 result
in hearing loss.
• This unit requires 12-volts to both the red and yellow power leads.
The unit will not work without 12-volts to both of these leads.
• Always 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.
