SEARCH FOR ERRORS
Possible Cause
The source equipment is giving signal on
only one channel.
One of the signal cables between audio source
and amplifier inputs has not yet been plugged
in or is defective.
One of the speaker cables is not correctly
connected or is defective.
The cable connections are not tight, the con-
nectors are dirty or a cable is defective.
The tone settings on the dials "TREBLE" or
"BASS" have not been selected correctly.
A record player has been connected to a line
level input without using a phono preampli-
fier.
No batteries inserted in the remote control,
batteries are not inserted correctly or are
depleted.
The line-of-sight between the remote control
and the unit is obstructed, the range was
exceeded or the hand unit was operated from
a position too far to one side.
The unit is not switched on.
See section "Net frequency noise" in the chapter "Tips".
Countermeasure
Check the audio source. You can try to use it
at a different amplifier for a test.
Check the cable connections, tighten them
if necessary.
Check and refasten the speaker cables at the
speaker terminal of the amplifier and at the
speaker's connectors. The cables coming
from both the speakers of a speaker pair must
not be connected to different terminal sets (e.g.
one A and one B) on the back of the amplifier.
Check the cables and cable connections.
Check the settings selected there.
Interconnect a phono preamplifier.
Check and replace the batteries if necessary.
Try to point the remote control at the front of
the unit only when the sight-line is clear,
within a 7-metre distance and, if possible,
facing the unit.
Switch on the unit.
