TROUBLESHOOTING
What appears to be trouble is not always serious. First make sure....
● Power cannot be turned on.
* Is the power cord unplugged?
● No sound from the speakers.
* Are headphones connected?
CD Player Section
● The CD player does not play.
* Is the CD upside down?
* Is the CD dirty?
● A certain portion of the CD does not play correctly.
* Is the CD scratched?
Cassette Deck Section
● Playback sound is at a very low level.
* Is the head dirty?
● The ONE TOUCH REC button does not function.
* Have the safety tabs of the cassette been broken off?
Tuner Section
● Reception is noisy.
* Try adjusting the antenna.

* Is the current time set correctly?
* Is the timer mode ( ) displayed?

Note:
Before making an important recording, be sure to make a test record-
ing first to check that the deck, etc. is working correctly.
● When the above remedies do not help
Many operations of this unit are performed by the control of a
microprocessor. If none of the buttons function, unplug the power
cord, wait for a while, then plug it back in. Reset the correct val-
ues for the clock and timer.
Cleaning is important!
When the tape is running, magnetic powder and dust naturally accu-
mulate on the heads, capstan and pinch roller. When they become too
dirty...
● Sound quality deteriorates.
● The output sound level drops.
● Previously recorded tape is not completely erased.
● Recording is not performed satisfactorily.
Therefore, you should clean the heads, etc. after every 10 hours of use
for optimal recording conditions.
Cleaning the heads, capstan and pinch roller
Open the cassette holder.
Clean the heads, pinch roller and capstan.
For effective cleaning, use a cleaning kit available from an audio store.
After cleaning, be sure that the cleaning fluid has dried completely be-
fore loading a cassette.
MAINTENANCE
Cautions:
1. Keep magnets and metallic objects away from the
head.
If the head becomes magnetized, noise will increase and the sound
will deteriorate. Demagnetize the head every 20–30 hours of use
with a head eraser (available from an audio store). (When demag-
netizing the head, the
button should be set to STANDBY.)
2. Do not use anything other than alcohol for cleaning.
Thinner and benzine will damage the rubber pinch roller.
Cleaning the lens
If the lens in the CD pickup is dirty, dropout, etc., could degrade sound.
Open the CD holder and clean the lens as shown.
● Use a blower (available from a camera store) to blow dust off the lens.
● If there are fingerprints, etc. on the lens, gently wipe clean with a
cotton swab.
