FAULT INDICATION SYSTEM
The
SmartPower
has a powerful protection system and fault indication system
designed to prevent damage to your hi-fi system and help you diagnose a
possible problem. If a fault persists, reset the amplifier via the rear panel
mains switch.
FAULT INDICATIONS
Standby light flashing Green / Yellow
This indicates overload in at least
one channel. If the problem is
temporary (e.g. excessive volume),
normal operation will resume after
ten seconds. If the fault indication
persists, there may be a problem
with the speakers or connections.
Switch off the power at the rear panel
and unplug the speaker cables. If the
fault indication clears when power is
re-applied, check the loudspeakers,
cables and plugs for loose strands of
wire causing a possible short circuit.
Standby light flashing Green
A fault has been reported from the
PSX-R
Switch off the power to the
SmartPower
and the
PSX-R
Switch
on again. If the problem does not
clear, return both units to your
Cyrus
distributor for checking.
The
PSX-R
is disconnected or
switched off.
Check there is power to the
PSX-R
and check the PSX-R connection to
the
SmartPower.
Standby light flashing Yellow / Red
The
SmartPower
has over heated.
Check the ventilation around the
SmartPower.
Allow the unit to cool
down before re-applying power.
MONO light flashing
The STEREO/MONO switch has
been changed whilst the amplifier is
operating.
Return the switch to its original
position.
If after taking remedial measures a fault condition remains, you should return
the
SmartPower
to your
Cyrus
appointed dealer or an authorised Service
Centre.
