Uninstalling the Radio
Procedure:
1 Before uninstalling the radio:
a Switch the radio off.
b Wait for a minimum of 4 seconds after the radio switch is released.
c Disconnect the 13.2 V main power supply.
2 Alternatively, turn off the main power supply without switching OFF the radio.
3.3
Installing DC Power Cable
CAUTION: This radio must be operated only in negative ground electrical systems. Operating
the radio on a positive ground system causes the cable fuse to short-circuit. Check the vehicle
ground polarity before you begin the installation.
Procedure:
1 Determine a routing plan, keeping in mind where to mount the radio as well as the following
factors:
a Whenever possible, avoid routing the cable above the catalytic converter.
b Make sure that the power cable never rests on sharp edges.
c Use grommets whenever a cable has to pass through a hole in a metal panel.
CAUTION: Improper handling with the power cable may cause shorting to ground.
Ensure that during radio installation the power cable fuse is removed. Make sure that
your power cable is not placed with the antenna in parallel. Interference can cause radio
to hang.
2 Locate an existing hole with the grommet in the vehicle fire wall, or use a 9.5 mm (3/8-inch) bit to
drill an access hole in the fire wall. Install a grommet with a 5 mm (3/16-inch) inside diameter
into the hole to protect the power cable.
CAUTION: Be careful not to damage existing wires.
3 From inside the vehicle, feed the red and black leads (without the lugs attached) through the
access hole and into the engine compartment.
