condensation may occur inside the lenses and 
display of the unit. Should this occur, the unit will 
not operate properly. In such a case, remove the disc 
and wait for about an hour until the moisture has 
evaporated.

• Do not subject discs to heat/high temperature. 

Avoid leaving them in a parked car or on a

attached.
The following malfunctions may result from using 
such discs:
– Inability to eject a disc (due to a label or sticker 

peeling off and jamming the eject mechanism).

– Inability to read audio data correctly (e.g., 

playback skipping, or no playback) due to heat 
shrinking of a sticker or label causing a disc to 
warp.
