Maintenance; Optional Remote Control Transmitter - Yamaha KX-W421 Owner's Manual

CLEANING OF THE TAPE PATH
Continued high quality performance of your deck is
dependent upon periodic cleaning of the heads, capstan,
pinch roller, and all surfaces over which the tape travels.
Normal use will cause an accumulation of dirt and dust on
the heads, capstans, and pinch rollers. This can lead to
poor sound quality, drop outs (intervals with no sound),
unsteady tape speed, loss of high frequency response, etc.
Thus, clean the heads and all surfaces over which the tape
travels with a commercially available cleaning cassette and
fluid type cleaner.

OPTIONAL REMOTE CONTROL TRANSMITTER

With the optional remote control transmitter RKX1, you can
operate this unit at your listening position. For details, refer
to the instruction manual supplied with the remote control
transmitter.

DEMAGNETIZATION
After 20-30 hours of use, enough residual magnetism will
build up on the heads to cause poor high frequency
reproduction. At this time you should use a commercially
available cassette tape-type head demagnetizer.
÷ When cleaning the tape path or demagnetizing the heads,
be sure to follow carefully the instructions of the
concerning materials such as cleaning fluid or head
demagnetizer.
