4.1 Service Connector (for ComPair)
For service diagnostics with ComPair, it is not necessary to
disassemble the set. You only have to connect the ComPair
interface box, via the appropriate cable, to the service
connector (on the rear of the set, see figure below), and start
the program (see also chapter 5).
4.2 Set Disassembly
Follow the disassemble instructions in described order.

4.2.3 Sub-woofer Removal
Caution: Do not disconnect the loudspeaker cable from the
subwoofer box when the set is operative, because the class-D
amplifier cannot handle a change in load during operation.
It is no problem when the subwoofer is disconnected before
operation, but a change from connected to disconnected
during operation can damage the amplifier.
1. Disconnect the loudspeaker cable at the top of the sub-
woofer box.
2. The subwoofer is fixed in the bottom plate with two 'rubber
feet'.
3. Pull the sub-woofer box upwards, and remove it.
4.3 Service Positions
This chassis has several predefined service positions, for
better accessibility. They are explained below in more detail.
