Sound reproduc- 1. Volume of SCA1 system set too low
tion too soft
SCA1 system does 1. The battery is flat
not rITond to
remote control
DM system hums 1. Signal line from amplifier to DM system too long
2. Signal line used is not fault-protected or the protection has
been damaged (defective)

Solution
Check connection
Switch to "ON"
Increase the volume using the volume control
Change the battery
Use shorter signal line
Change signal line for a fault-protected line
A ground loop can be generated when two or more devices connected via a signal line (cinch) are
plugged into separate sockets (e. g. amplifier and computer). All devices connected to the amplifier
should be plugged into the same multiple socket outlet
Switch off possible sources of interference to test; unplug the device concerned to see if the hum-
ming noise disappears or connect the source of interference to a different circuit (L1, L2
or L3). (Where necessary take advice from your electrician.)
Insert a special "ferrite common mode filter" (available from specialist retailers) between the amplifier
and the DM system to eliminate the humming
Disconnect and rotate the mains plug to reduce the so-called ripple voltage.
(Particularly important if the amplifier is not earthed)
