Notes on discs
Before playing, wipe the disc with a cleaning cloth from
the center out to the edge.
Do not clean discs with solvents, such as benzine
thinner, or commercially available cleaners or anti-
static spray intended for vinyl LPs.
Do not expose discs to direct sunlight or heat sources
such as hot air ducts, nor leave it in a car parked in
, FUNCTION
, and
at the same
direct sunlight.
On safety
The unit is not disconnected from the AC power source
(mains) as long as it is connected to the wall outlet,
even if the unit itself has been turned off.
Completely disconnect the power cord (mains lead)
from the wall socket (mains) if it is not going to be used
for an extended period of time. When unplugging the
unit, always grip the plug. Never pull the cord itself.
Should any solid object or liquid get into the system,
unplug the system, and have it checked by qualified
personnel before operating it again.
AC power cord must be changed only at the qualified
service shop.
On placement
Do not place the system in an inclined position or in
locations that are extremely hot, cold, dusty, dirty, or
humid or lacking adequate ventilation, or subject to
vibration, direct sunlight or a bright light.
Be careful when placing the unit or speakers on
surfaces that have been specially treated (for example,
with wax, oil, polish) as staining or discoloration of the
during playback or pause.
surface may result.
during
If the system is brought directly from a cold to a warm
location or is placed in a very damp room, moisture
may condense on the lens inside the CD player, and
cause the system to malfunction. In this situation,
remove the disc, and leave the system turned on for
about an hour until the moisture evaporates.
On heat buildup
Heat buildup on the unit during operation is normal
and is not cause for alarm.
Do not touch the cabinet if it has been used
continuously at a high volume because the cabinet may
have become hot.
Do not obstruct the ventilation holes.
On the speaker system
This speaker system is not magnetically shielded, and
the picture on nearby TV sets may become magnetically
distorted. In this situation, turn off the TV, wait 15 to 30
minutes, and turn it back on.
If there is no improvement, move the speakers far away
from the TV.
Cleaning the cabinet
Clean this system with a soft cloth slightly moistened
with a mild detergent solution. Do not use any type
of abrasive pad, scouring powder, or solvent, such as
thinner, benzine, or alcohol.
