Care and Maintenance
« Enough care must be taken against battery overdischarge caused
by fong operation of the set at a high sound level when the
engine is not running ar is idling.
@ The protection circuitry will operate instantaneously should any
malfunctions occur, shutting off all sound. Under such circum-
stances, disconnect the power of the car stereo system, check the
wiring for any possible causes and correct them before operating
the stereo system again.
« When replacing the fuse, replace it with a fuse having the correct
capacity.
e Dust the heat sinks occasionally so that they will not become
clogged.
