expected, first check the items in the
following list. If you cannot deter-
mine the source of the problem,
contact your dealer or authorized
Harman Kardon service representa-
tive.

Power cord is not plugged into
power outlet.
Wall outlet or extension cord is
faulty. Check for poor connec-
tions.

BUT THE CD DOES NOT PLAY
The disc may have been inserted
upside down. Make sure the label
side is facing up.
Moisture may have formed on the
laser/receptor inside the unit.
This sometimes occurs in damp
climates or when the unit is
moved from a cold to a warm
area. Leave the unit turned on at
room temperature for 30 minutes
to allow the moisture to evapo-
rate, then play your disc.

THE SOUND SKIPS OR STUTTERS
DURING PLAYBACK
The disc may be dirty or damaged.
The unit may have been placed on
an unstable surface. Isolate the
unit from excessive vibration by
placing it on a firmer surface or
farther away from your speakers.
THE SOUND IS CONTINUOUSLY
DISTORTED
The cables from the HD710 have
been plugged into the wrong input
jacks on your integrated amplifier/
receiver/preamplifier. Make sure
you have not plugged the unit into
