ammonia or abrasives.
FAULTS AND THEIR LIKELY CAUSES
If a fault occurs, run through the points listed below before
taking your player for repair. Check whether:
- condensation has formed on the lens of the laser due to a
dramatic change in temperature; this will disappear
automatically after some time;
- the CD has been inserted correctly with the printed side up
and that there is a CD in the compartment;
- the CD is dirty, badly scratched or warped;
- the player has been connected to the PHONO socket of the
amplifier;
- the sound level of the CD player has been set at normal
level. See 'ADJUSTING THE SOUND LEVEL' to change the
setting.
If the fault remains, try to clear it by switching the player off
and on again.
If this also fails to help, consult your dealer.
