WARNINGS BEFORE INSTALLATION

Important warnings to take note of BEFORE installing the unit:

Damage caused by incorrect installation or usage is NOT covered by the warranty. PLEASE take the time to read the installation instructions carefully.

To validate the warranty please ensure that the unit is installed by a professional, VAT registered car audio installation company.

• To avoid shorts in your vehicle’s electrical system, be sure to disconnect the

battery cable before beginning installation.

• This unit is intended for vehicles with a 12-volt battery and negative grounding.

Before installing the unit in a recreational vehicle, truck, or bus, check that the

battery voltage is 12 volts.

• Remove the two transport screws from the top of the unit before installation.

• The black lead is ground� A good chassis ground requires a tight connection

to ground. The area should be free from rust, paint or any form of dirt. Please

ground this lead separately from the ground of high-current products such as

power amps. If you ground the products together and the ground becomes

detached, there is a risk of damage to the products or re.

• Be sure to connect the color coded leads according to the wiring diagram.

Incorrect connections may cause the unit to malfunction or damage the

vehicle’s electrical system. Wires for this product and those for other products

may be dierent colors even if they have the same function. When connecting

this product to another product, refer to the supplied installation manuals of

both products and connect wires that have the same function.

• Be sure to connect the negative (-) speaker leads to the negative (-) speaker

terminal. Never connect the negative (-) speaker leads to chassis ground.

• The unit is only designed for use with 4 speakers. Do not combine outputs

for use with 2 speakers. Do not ground negative speaker leads to the chassis

ground.

• Speakers connected to this unit must be high-power units with a minimum

rating of 45W and impedance of 4 to 8 ohms. Connecting speakers with output

and/or impedance values other than those noted here will result in damage to

the head unit and the speakers. Check the condition of your speakers carefully.

Connecting this unit to old or degraded speakers may result in a fault which will

damage the audio IC and invalidate the warranty.

5

• If this unit is installed in a vehicle that does not have an ACC (accessory) position

on the ignition switch, the red lead of the unit should be connected to a terminal coupled with ignition switch ON/O operations. If this is not done, the vehicle battery may be drained when you are away from the vehicle for several hours.

• Secure the wiring with cable clamps or adhesive tape. To protect the wiring,

wrap adhesive tape around them where they lie against metal parts. To avoid short-circuiting, cover all disconnected lead with insulating tape. There is a possibility of short-circuiting if the leads are not insulated.

• Route and secure all wiring so it cannot touch any moving parts, such as the

gear lever and handbrake. Do not route wiring in places that get hot, such as near the heater outlet. If the insulation of the wiring melts or gets torn, there is a danger of the wiring short-circuiting to the vehicle’s body.

• Don’t pass the yellow lead through a hole into the engine compartment to

connect to the battery. This will damage the lead’s insulation and cause a very dangerous short.

• Do not short any leads. If you do, the protection circuit may fail to work when it

should.

• Never feed power to other equipment by cutting the insulation of the power

supply lead of the unit and tapping into the lead. The current capacity of the lead will be exceeded, causing overheating.

• Since an unique audio I/C circuit is employed, never wire the unit so the

speaker leads are directly grounded or the left (-) and right (-) speaker leads are common.

• When this product’s source is switched ON, a control signal is outputted

through the blue lead. Connect to an external power amp’s system remote control or the car’s Auto-antenna relay control terminal (max. 300mA 12 V DC). If the car features a glass antenna, connect to the antenna booster power supply terminal.

• When an external power amp is being used with this system, do not connect

the blue lead to the amp’s power terminal. Likewise, do not connect the blue lead to the power terminal of the auto-antenna. Such connection could cause excessive current drain and a major malfunction. Refer to the relevant owner’s manual for details on connecting the power amp and other units, then make the connections correctly.

• Do not block any vents or heater panels. Blocking them will cause heat to build

up and may result in re.

• Make sure that the unit has a good chassis ground. A good ground connection

will eliminate most electrical noise. A good chassis ground requires a tight connection to the vehicles metal chassis. The area around the ground connection should be clean, bare metal without rust, paint, plastic or dirt.

6

DMR2116

• If noise is still experienced when the motor of the vehicle accelerates, a choke

should be placed in line with the power to the unit. The installation company will know what is required.

• When replacing the fuse(s) the replacement must be of the same amperage as

shown on the fuse holder. Never replace a fuse with another fuse of a dierent value. If the fuse blows again please contact your installation company.

• Double check that all wiring and connections are correct before re-connecting

the battery and turning on the unit.

• After completing the installation and before operating the unit, reconnect the

battery, then press the RESET button with a pointed object, such as a ball-point pen to set the unit to its initial status.
