Basic Procedure

1. 

Remove the key from the ignition switch, then disconnect the   

terminal of the car battery.

2. 

Make proper input and output wire connections.

3. 

Install the unit to your car.

4. 

Reconnect the   terminal of the car battery.

5. 

Reset the unit.

Warning



The unit can only be installed in a car with a 12 V DC power 

supply, negative ground.



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.



Disconnect the battery’s negative terminal and make all electrical 

connections before installing the unit.



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.



Be sure to ground this unit to the car’s chassis again after 

installation.



If the power is not turned ON, the speaker wire may have a short-

circuit or touched the chassis of the vehicle and the protection 

function may have been activated. Therefore, the speaker wire 

should be checked.

Caution



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, as with battery wires, the 

battery may die.



Install this unit in the console of your vehicle. Make sure the 

faceplate will not hit the lid of the console (if any) when closing 

and opening.



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.



If the fuse blows, first make sure the wires are not touching to 

cause a short circuit, then replace the old fuse with one that has 

the same rating.



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 the connectors either to both the front output terminals 

or to both the rear output terminals (do not mix front and rear).



Mounting and wiring this product requires skills and experience. 

For safety’s sake, leave this work to professionals.

If you experience problems during installation, consult your 

TELEFUNKEN dealer.
