Troubleshooting Chart
Many potential "problems" can be resolved by the owner without calling a service techni-
cian.
If something is wrong with this product, check the following before calling your authorised
SHARP dealer or service centre.
General
CD player
Tuner
Cassette deck
Remote control
Condensation
Sudden temperature changes, storage or operation in an extremely humid environ-
ment may cause condensation inside the cabinet (CD pickup, tape heads, etc.) or on
the transmitter LED 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 LED with a soft cloth before operating
the unit.
Symptom Possible cause
The clock is not on time. Didapower failure occur?Resetthe clock.
Whenabutton ispressed,the
unit does not respond. Set this unit to the power stand-by mode and then turn it back on.
If the unit still malfunctions, reset it.
No sound is heard. Is the volume level set to "0"?
Are the headphones connected?
Are the speaker wires disconnected?
Symptom Possible cause
Playback does not start. Is the disc loaded upside-down?
Playback stops in the middle
or is not performed properly. Does the disc satisfy the standards?
Is the disc distorted or scratched?
Playback sounds are
skipped, or stopped in the
middle of a track.
Is the unit located near excessive vibrations?
Is the disc very dirty?
Has condensation formed inside the unit?
Symptom Possible cause
Radio makes unusual noise
consecutively. Is the unit placed near the TV or computer?
Is the FM/AM loop aerial placed properly? Move the
AC power lead away from the aerial if located near.
Symptom Possible cause
Cannot record. Is the erase-protection tab removed?
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. Is there any slack? Is the tape stretched?
Cannot hear treble. Are the capstan, pinch roller, or heads dirty?
Sound fluctuation.
Cannot remove the tape. If a power failure occurs during playback, the heads
remain engaged with the tape. Do not open the
compartment forcibly. Wait until electricity resumes.
Symptom Possible cause
The remote control does not
operate. Is the AC power lead of the stereo system plugged in?
Is the battery polarity correct?
Are the batteries dead?
Is the distance or angle incorrect?
Does the remote control sensor receive strong
light?
If trouble occurs
When this product is subjected to strong external interference (mechanical shock,
excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is
operated incorrectly, it may malfunction.
If such a problem occurs, do the following:
1 Set the unit to the stand-by mode and turn the power on again.
2 If the unit is not restored in the previous operation, unplug and plug in the unit,
and then turn the power on.
Clearing all the memory (reset)
If neither operation above restores the unit, clear all the memory by following
the instructions below.
1 Press the ON/STAND-BY button to enter the power stand-by mode.
2 Whilst pressing down the VOLUME button, press the ON/STAND-BY button
until "ALL CLEAR" appears.

Remote Control
Notes concerning use:
Replace the batteries if the operating distance is reduced or if the operation

Using the Radio Data System (RDS) (CD-CH1500H Only)
RDS is a broadcasting service which a growing number of FM stations provide.
These FM stations send additional signals along with their regular programme
signals. They send their station names, and information about the type of pro-
gramme such as sports or music, etc.
When tuned to an RDS station, "RDS" and the station name will be displayed.
"TP" (Traffic Programme) will appear on the display when the received broadcast car-
ries traffic information, and "TA" (Traffic Announcement) will appear whilst a traffic
information is on air.
"EON" will appear whilst the EON (Enhanced Other Networks information) data is
broadcast.
"PTYI" (Dynamic PTY Indicator) will appear whilst the Dynamic PTY station is
received.
"RT" (Radio Text) will appear whilst the unit receives the Radio text data.
"CT" (Clock Time) will appear whilst the unit receives the RDS CT data.
You can control the RDS by using the remote control only.
Information provided by RDS
Each time the DISP MODE button is pressed, the display will switch as follows:
When you are tuning in to a station other than an RDS station or to an RDS station
which sends weak signal, the display will change in the following order:
Station name (PS) Frequency

ging the unit into an AC socket. If necessary, adjust the selector to correspond to the
AC power voltage used in your area.
Turn the selector with a screwdriver until the appropriate voltage number
appears in the window (110 V, 127 V, 220 V or 230 V - 240 V AC).
Connecting the AC power lead
