Discs that this system CANNOT play
CD-ROM
CD-R/CD-RW other than those recorded in music CD 
format or MP3 format conforming to ISO9660 Level 
1/Level 2, Joliet or multisession
CD-R/CD-RW recorded in multisession that have not 
ended by “closing the session”
CD-R/CD-RW of poor recording quality, CD-R/CD-
RW that have scratches or are dirty, or CD-R/CD-RW 
recorded with an incompatible recording device

when touched
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 
direct sunlight.
On safety
e unit is not disconnected from the AC power source 
(mains) as long as it is connected to the wall socket, 
even if the unit itself has been turned o.
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 qualied 
personnel before operating it again.
e AC power cord can be changed only by a qualied 
service facility.
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 
surface may result.
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
is speaker system is not magnetically shielded, and 
the picture on nearby TV sets may become magnetically 
distorted. In this situation, turn o 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 so 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.
