POINTS TO OBSERVE FOR SAFE USAGE

DO NOT INSTALL IN LOCATIONS WITH HIGH MOISTURE

OR DUST

Avoid installing the unit in locations with high incidence of mois­
ture or dust. Moisture or dust that penetrates into this unit may
cause smoke or fire.

MAKE THE CORRECT CONNECTIONS
Failure to make the correct connections can cause fire or acci­

dent to occur.

ARRANGE THE WIRING SO IT IS NOT CRIMPED OR

PINCHED
Route the cables and wiring so as not be crimped by moving

parts like seat rail or make contact with sharp or pointed spots

which might damage the wiring.

When playing 3-inch CDs in the 7909, do not use an adaptor

ring. Adaptor rings may become stuck inside the player and

damage the mechanism.

irregularities. The outer and inner edges should be round and

smooth. Use of irregularly shaped discs may cause damage

to the mechanism.
