Audio CD

CD-R/CD-RW (audio data/MP3 files)

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

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

CD-R/CD-RW which is finalized incorrectly

Discs containing files other than MPEG 1 Audio Layer-

3 (MP3) files

Discs of non-standard shape (for example, heart, 

square, star)

Discs that have adhesive tape, paper, or sticker attached 

to them

Rental or used discs with attached seals where the glue 

extends beyond the seal

Discs that have labels printed using ink that feels tacky 

when touched

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.

Completely disconnect the power cord (mains lead) 

from the wall outlet (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.

The AC power cord can be changed only by a qualified 

service facility.

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.

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.

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.

Clean this system with a soft cloth slightly moistened 

with a mild detergent solution. Do not use any type of 

abrasive pads, scouring powder, or solvents, such as 

thinner, benzine, or alcohol.
