Power Cable
Caution: This radio is designed to operate from
a nominal 12V negative ground supply and may
draw up to 8A of current. The radio will tolerate
a supply voltage range of 10.8V to 16.0V at the radio.
In vehicles with a supply voltage greater than 16.0V,
such as many trucks, it is essential to provide a suitably
rated DC to DC converter. This will isolate the radio from
excessive battery voltage and provide the correct DC
operating conditions.
Installing the Power Cable
Caution: Disconnecting the vehicle's battery
may cause problems with some electronic
equipment, such as vehicle alarms, engine
management systems and in-car entertainment systems.
Check that the vehicle owner has the necessary informa-
tion to make all electronic equipment function correctly
after battery reconnection.
1. Disconnect the vehicle's battery, unless specifically
prohibited from doing so by the customer, vehicle
manufacturer, agent or supplier.
If the battery is not disconnected, exercise extreme
caution throughout the installation and install the
fuses only when the installation is ready to be
checked (see "Installation Checks" on page 28).
2. Determine where the power cable will be routed.
Caution: The power cable should be
protected from engine heat, sharp edges
and from being pinched or crushed.
