Condensation
Sudden temperature changes, storage or operation in an extremely
humid environment may cause condensation inside the cabinet (CD
pickup, tape heads, etc.) or on the transmitter on the remote control.
Condensation can cause the unit to malfunction. If this happens,
leave the power on with no disc (or cassette) in the unit until normal
playback is possible (about 1 hour). Wipe off any condensation on
the transmitter with a soft cloth before operating the unit.
Symptom
Possible cause
Cannot record.
Is the erase-prevention tab re-
moved?
Cannot record tracks with
proper sound quality.
Is it a normal tape? (You cannot
record on a metal or CrO tape.)
Cannot erase completely.
Sound skipping.
Cannot hear treble.
Sound fluctuation.
Is there any slack?
Is the tape stretched?
Are the capstans, pinch rollers,
or heads dirty?
Cannot remove the tape.
If a power failure occurs during
playback, the heads remain en-
gaged with the tape. Do not open
the compartment with great
force.
Symptom
Possible cause
The remote control does
not operate.
Is the AC power lead of the unit
plugged in?
Is the battery polarity correct?
Are the batteries dead?
Is the distance or angle incor-
rect?
Does the remote control sensor
receive strong light?
Symptom
Possible cause
The radio makes unusual
noises continuously.
Is the unit placed near the TV or
computer?
Is the FM aerial or AM loop aerial
placed properly? Move the aerial
away from the AC power lead if
it's located nearby.
