ˋ

ˎ A DualDisc is a two sided disc product which 

mates DVD recorded material on one side with 
digital audio material on the other side. 
However, since the audio material side does 
not conform to the Compact Disc (CD) 
standard, playback on this product is not 
guaranteed.

ˋ

ˎ This product is designed to playback discs that 

conform to the Compact Disc (CD) standard. 
Recently, various music discs encoded with 
copyright protection technologies are 
marketed by some record companies. Please 
be aware that among those discs, there are 
some that do not conform to the CD standard 
and may not be playable by this product.

ˋ

ˎ As the laser beam used in the CD player 

section is harmful to eyes, do not attempt to 
disassemble the casing. Refer servicing to 
qualified personnel only.

ˋ

ˎ Should any solid object or liquid fall into the 

unit, unplug the unit, and have it checked by 
qualified personnel before operating it any 
further.

keep personal credit cards using magnetic 
coding or spring-wound watches away from 
the unit to prevent possible damage from the 
magnet.

ˋ

ˎ Condensation may form on outer surfaces or 

internally, and cause the unit to malfunction if 
the unit is suddenly moved from a cold to a 
warm environment. If condensation forms, turn 
off the unit, and leave the unit off until the 
moisture evaporates. Do not use the unit until 
the condensation has fully evaporated.
