Notes:
Read this entire manual before you
begin installation.
• This unit is designed for use in boats.
Its water resistant design makes it a
good choice for other vehicles (such
as off-road) that may be exposed to
water or other conditions that might
harm a non-marine unit.
• Choose a mounting location where the
unit will not interfere with the driver’s
operation or with other equipment in
the vehicle.
• Before completing the final installation
of the unit make all your connections,
verify your wiring, and make sure the
unit operates properly.
• Use only the parts included with the
unit to ensure proper installation. The
use of unauthorized parts can cause
malfunctions.
• Consult with your nearest dealer if
installation requires the drilling of holes
or other modifications to the boat.
• Install the unit where it does not get in
the driver’s way and cannot injure the
passenger if there is a sudden stop,
like an emergency stop.
• Do not use a mounting angle greater
than 30 degrees (above or below)
straight horizontal. Doing so will
increase the possibility of CD skipping
30˚
• Avoid installing the unit where it would
be subject to high temperature, such
as from direct sunlight, or from hot air,
from the heater, or where it would be
subject to dust, dirt or excessive
vibration.
TRANSPORT SCREWS
Before installing the unit remove the two
transport screws on the top of the unit
chassis.
