Installation and Connections
Before installing or connecting the unit, please
read the following and pages 2 and 3 of this
manual thoroughly for proper use.
Warning
MAKE THE CORRECT CONNECTIONS.
Failure to make the proper connections may result in fire
or product damage.
USE ONLY IN CARS WITH A 12 VOLT NEGATIVE
GROUND.
(Check with your dealer if you are not sure.) Failure to do
so may result in fire, etc.
BEFORE WIRING, DISCONNECT THE CABLE FROM
THE NEGATIVE BATTERY TERMINAL.
Failure to do so may result in electric shock or injury due
to electrical shorts.
DO NOT ALLOW CABLES TO BECOME ENTANGLED
IN SURROUNDING OBJECTS.
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, gear lever, brake pedals, etc. can be extremely
hazardous.
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 chassis 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.
DO NOT USE BOLTS OR NUTS IN THE BRAKE OR
STEERING SYSTEMS TO MAKE GROUND
CONNECTIONS.
Bolts or nuts used for the brake or steering systems (or
any other safety-related system), or tanks should NEVER
be used for installations or ground connections. Using
such parts could disable control of the vehicle and cause
fire etc.
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.
Caution
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 SECURELY.
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 seat rails) 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 wires
insulation from being cut by the metal edge of the hole.
DO NOT INSTALL IN LOCATIONS WITH HIGH
MOISTURE OR DUST.
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.
Precautions
•Be sure to disconnect the cable from the (–) battery post
before installing your MDM-7741R. This will reduce any
chance of damage to the unit in case of a short-circuit.
•Be sure to connect the colour coded leads according to
the diagram. Incorrect connections may cause the unit to
malfunction or damage to the vehicle's electrical system.
•When making connections to the vehicle'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
MDM-7741R to the fuse box, make sure the fuse for the
intended circuit of the MDM-7741R has the appropriate
amperage. Failure to do so may result in damage to the
unit and/or the vehicle. When in doubt, consult your
ALPINE dealer.
•The MDM-7741R 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 vehicle body.
