MAKE THE CORRECT CONNECTIONS.
Failure to make the proper connections may result in fire or product
DO NOT CONNECT A POWER SUPPLY OTHER THAN A DC
12V NEGATIVE GROUND TYPE.
Failure to do so may result in accident or fire.
BEFORE WIRING, DISCONNECT THE CABLE FROM THE
NEGATIVE BATTERY TERMINAL.
Failure to do so may result in electric shock or injury due to
DO NOT SPLICE INTO ELECTRICAL CABLES.
Never cut away cable insulation to supply power to other
equipment. Doing so will exceed the current carrying capacity of
the wire and result in fire or electric shock.
DO NOT DAMAGE PIPE OR WIRING WHEN DRILLING HOLES.
When drilling holes in the hull for installation, take precautions so
as not to contact, damage or obstruct pipes, fuel lines, tanks or
electrical wiring. Failure to take such precautions may result in fire.
KEEP SMALL OBJECTS SUCH AS BOLTS OR SCREWS OUT
OF THE REACH OF CHILDREN.
Swallowing them may result in serious injury. If swallowed, consult
a physician immediately.
DO NOT INSTALL IN LOCATIONS WHICH MIGHT HINDER
BOAT OPERATION, SUCH AS THE STEERING WHEEL OR
Doing so may obstruct forward vision or hamper movement etc.
and results in serious accident.
DO NOT ALLOW CABLES TO BECOME ENTANGLED IN
Arrange wiring and cables in compliance with the manual to
prevent obstructions when driving. Cables or wiring that obstruct or
hang up on places such as the steering wheel, throttle controls, etc.
can be extremely hazardous.
HAVE THE WIRING AND INSTALLATION DONE BY EXPERTS.
The wiring and installation of this unit requires special technical
skill and experience. To ensure safety, always contact the dealer
where you purchased this product to have the work done.
USE SPECIFIED ACCESSORY PARTS AND INSTALL THEM
Be sure to use only the specified accessory parts. Use of other than
designated parts may damage this unit internally or may not
securely install the unit in place. This may cause parts to become
loose resulting in hazards or product failure.
ARRANGE THE WIRING SO IT IS NOT CRIMPED OR
PINCHED BY A SHARP METAL EDGE.
Route the cables and wiring away from moving parts (like the hatch
covers or engine covers) or sharp or pointed edges. This will
prevent crimping and damage to the wiring. If wiring passes
through a hole in metal, use a rubber grommet to prevent the wire’s
insulation from being cut by the metal edge of the hole.
DO NOT INSTALL IN LOCATIONS WITH HIGH MOISTURE OR
Avoid installing the unit in locations with high incidence of
moisture or dust. Moisture or dust that penetrates into this unit may
result in product failure.
• Be sure to disconnect the cable from the (–) battery post before
installing your CDA-118M. This will reduce any chance of
damage to the unit in case of a short-circuit.
• Be sure to connect the color coded leads according to the
diagram. Incorrect connections may cause the unit to
malfunction or damage to the boat’s electrical system.
• When making connections to the boat’s electrical system, be
aware of the factory installed components (e.g. on-board
computer). Do not tap into these leads to provide power for this
unit. When connecting the CDA-118M to the fuse box, make
sure the fuse for the intended circuit of the CDA-118M has the
appropriate amperage. Failure to do so may result in damage to
the unit and/or the boat. When in doubt, consult your Alpine
• The CDA-118M uses female RCA-type jacks for connection to
other units (e.g. amplifier) having RCA connectors. You may
need an adaptor to connect other units. If so, please contact your
authorized Alpine dealer for assistance.
• Be sure to connect the speaker (–) leads to the speaker (–)
terminal. Never connect left and right channel speaker cables to
each other or to the boat body.
Please record the serial number of your unit in the space provided
below and keep it as a permanent record. The serial number or the
engraved serial number is located on the bottom of the unit.
