Specifications

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 require special technical skills 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 wire 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 a high incidence of moisture or dust. Moisture or dust that penetrates 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 color-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.

IMPORTAN T: Please record the serial number of your unit in the space provided below and keep it as a permanent record. The serial number plate is located on the bottom of the unit.

When your vehicle has the Bracket, mount the long hex bolt onto the rear panel of the MDM-7741R and put the Rubber Cap on the hex bolt. If your vehicle does not have the Mounting Support, reinforce the head unit with the metal mounting strap (not supplied). Connect all the leads of the MDM-7741R according to details described in the CONNECTION section.

NOTE For the screw ∗, provide a proper screw to the chassis installing location.

Slide the MDM-7741R into the dashboard. When the unit is in place, make sure the locking pins are fully seated in the down position. This can be done by pressing firmly in on the unit while pushing the locking pin down with a small screwdriver. This ensures that the unit is properly locked and will not accidentally come out from the dashboard. Install the Detachable Front Panel.

Removal

1. Remove the detachable front panel.
2. Use a small screwdriver (or similar tool) to push the locking pins to the “up” position (see above drawing). As each pin is unlocked, gently pull out on the unit to make sure it does not relock before unlocking the second pin.
3. Pull the unit out, keeping it unlocked as you do so.
