CONNECTION/INSTALLATION

Before installing the unit

V WARNING

• If you connect the ignition wire (red) and the

battery wire (yellow) to the car chassis (ground),

you may cause a short circuit, that in turn may

start a fire. Always connect those wires to the

power source running through the fuse box.

• Do not cut out the fuse from the ignition wire (red)

and the battery wire (yellow). The power supply

must be connected to the wires via the fuse.

V Precautions on installation and connection

• Mounting and wiring this product requires

skills and experience. For best safety, leave the

mounting and wiring work to professionals.

• Make sure to ground the unit to a negative 12 V

DC power supply.

• Do not install the unit in a spot exposed to direct

sunlight or excessive heat or humidity. Also avoid

places with too much dust or the possibility of

water splashing.

• Do not use your own screws. Use only the screws

provided. If you use the wrong screws, you could

damage the unit.

• If the power is not turned on (“Miswiring

DC Offset

Error”, “Warning DC Offset Error” is displayed),

the speaker wire may have a short circuit or

have touched the chassis of the vehicle and the

protection function may have been activated.

Therefore, the speaker wire should be checked.

• If your car’s ignition does not have an ACC

position, connect the ignition wires to a power

source that can be turned on and off with the

ignition key. If you connect the ignition wire to a

power source with a constant voltage supply, such

as with battery wires, the battery may be drained.

• Only for DDX771:

If the console has a lid, make sure to install the

unit so that the monitor panel will not hit the lid

when closing and opening.

• If the fuse blows, first make sure the wires are not

touching to cause a short circuit, then replace the

old fuse with one with the same rating.

• Insulate unconnected wires with vinyl tape or

other similar material. To prevent a short circuit,

do not remove the caps on the ends of the

unconnected wires or the terminals.

• Connect the speaker wires correctly to the

terminals to which they correspond. The unit may

be damaged or fail to work if you share the

wires or ground them to any metal part in the car.

• When only two speakers are being connected to

the system, connect both connectors either to

the front output terminals or to the rear output

terminals (do not mix front and rear). For example,

if you connect the connector of the left speaker

to a front output terminal, do not connect the

connector to a rear output terminal.

• After the unit is installed, check whether the brake

lamps, blinkers, wipers, etc. on the car are working

properly.

• Mount the unit so that the mounting angle is 30°

or less.

• Do not press hard on the panel surface when

installing the unit to the vehicle. Otherwise scars,

damage, or failure may result.

V CAUTION

Install this unit in the console of your vehicle.

Do not touch the metal part of this unit during and

shortly after the use of the unit. Metal parts such as

the heat sink and enclosure become hot.
