Sony XVM-R90D Operating Instructions Manual page 5

On heat build-up
Heat may build up in the player if it is used for
an extended period of time. This, however, is
not a malfunction.
Moisture condensation
On a rainy day or in a very damp area,
moisture condensation may occur inside the
lenses. Should this occur, the player will not
operate properly. In such a case, remove the
disc and wait for about an hour until the
moisture has evaporated.
To maintain high sound quality
Be careful not to splash juice or other soft
drinks onto the player or discs.

properly, referring to the installation and
wiring diagrams in this operating manual.
Improper installation may result in fire or

• Before installation, be sure to turn the
ignition switch to the OFF position or take
the key out. Installing this unit with the
