The loudspeaker line indicators provide information
about failing loudspeaker lines. They indicate short-
circuit (see section 18.11.3) and impedance supervision
(see section 18.11.2) faults. If a loudspeaker line
indicator lights, check the wiring of the indicated
loudspeaker line and try to solve the fault. If it not
possible to determine the fault, contact your dealer.
If supervision is disabled (see chapter 18), the fault
indicators do not function and the Disabled indicator is
lit (see figure 28.5).
The availability of the indicators can be tested with the
Indicator test button (see figure 5.1, no. 11).
