Trouble shooting

Cause:
The speaker leads are not connected 'in phase'.
Remedy:
Check the connections between the speaker leads, the speakers
and the amplifier speaker terminals, referring to the wiring
diagram, and correct where necessary.
Cause:
The speaker is located too close to the wall or in a room corner.
Remedy:
Keep the speakers at least 50 cm away from the side walls, or
alter the setting of the 'Bass' switch on the rear of the speaker.
Cause 1:
The amplifier's Protection circuit has tripped due to overheating
or overloading.
Remedy:
Reduce volume; if the amplifier does not switch itself on again
after about 20 seconds, then it has become too hot. Leave it
switched off for a few minutes to cool down.
Cause 2:
Short-circuit in the speaker leads; e. g. by stray cable 'whiskers'
at the terminal clamps, or due to mechanical damage to the
cable.
Remedy:
Check the speaker leads and terminal clamps. Twist wire ends
together tightly, or fit cable end sleeves. Replace defective
cables.
