c) Disassembly

• Remove the front control panel.
• Carefully remove the plastic frame in the front of the system, by bending it slightly to the outside and
pulling it off from the unit.
• Insert the two unlocking keys into the lateral slots in installation frame until the device unlocks.
• Remove the fastening screw at the back of the unit, if necessary.
• Carefully pull out the car radio from the installation frame with the unlocking keys.
• Remove the plug connections at the back of the device.

9. Electric connection

The electric connection should always be carried out by a specialist.
To avoid short-circuits and resulting damages of the car radio, the negative pole (ground) of the
vehicle battery must be disconnected during connection.
Only connect the negative pole of the battery, when you have completely connected the system
and checked the connections.
Use only a voltmeter or a diode test lamp to check the voltage of the vehicle system leads, as
normal test lamps consume excessive voltage and may thus damage the vehicle's electronics.
When laying the cables, make sure that they are not squeezed or abraded on sharp edges. Use
rubber grommets for the lead-though points.
The line towards the loudspeakers must be a bifilar cable. Insulate the bare wires at the con-
necting terminals. Ensure there are no sharp edges, which could damage the cables.
Only use loudspeakers that have a sufficiently high power rating (see „Technical Data").
Ensure that all the loudspeakers have the correct polarity, i.e. the plus and minus signs must
match.
