IMPORTANT SERVICE NOTES (FOR U.S.A. ONLY)
BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.
1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the chassis
and other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials,
cabinet, terminal board, adjustment and compartment covers
or shields, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage
current in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5k ohm, 10 watt resistor
paralleled by a 0.15µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher,
sensitivity to measure the AC voltage drop across the
resistor (See diagram).
* Connect the resistor connection to all exposed metal parts
having a return path to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.
All check must be repeated with the AC line cord plug connection
reversed.
Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp.
AC.) or more is excessive and indicates a potential shock
hazard which must be corrected before returning the audio
product to the owner.

Troubleshooting Chart
Many potential “problems” can be resolved by the owner without calling a service technician. If something is wrong with this product, check the following before calling your
authorized SHARP dealer or service center.
Tuner
Symptom
Radio makes unusual noise consecutively.
Possible cause
Is the unit placed near the TV or computer?
Is the FM/AM loop antenna placed properly?
Move the AC power cord away from the
antenna if located near.
General
Symptom
The clock is not on time.
When a button is pressed, the unit
does not respond.
No sound is heard.
The balance between the left and
right channels is bad.
Hum or excessive noise.
No sound is heard, or the sound
is too low, from the center or surround speakers.
The TIMER indicator is flashing.
CD player
Symptom
Playback does not start.
Playback stops in the middle or is
not performed properly.
Playback sounds are skipped, or
stopped in the middle of a track.
Possible cause
Is the disc loaded upside down?
Does the disc satisfy the standards?
Is the disc distorted or scratched?
Is the unit located near excessive vibrations?
Is the disc very dirty?
Has condensation formed inside the
unit?
Possible cause
Did a power failure occur?
Reset the clock.
Set this unit to the power stand-by mode
and then turn it back on.
If the unit still malfunctions, reset it.
Is the volume level set to “0”?
Are the headphones connected?
Are the speaker wires disconnected?
Are the front and surround speakers
connected to the correct left and right
channels?
If an external unit is connected, are the
left and right channels connected properly?
Is the speaker cord plugged in correctly?
Does the speaker cord run past other
electronic equipment?
Are the plugs or terminals dirty?
Is the “SP SIZE” item set to “NO” in the
“SET UP” operation?
Is the volume too low?
Is the speaker wire shorted?
Was the unit used at high volume for
many hours?
Cassette deck
Symptom
Cannot record.
Cannot record tracks with proper
sound quality.
Cannot erase completely.
Sound skipping.
Cannot hear treble.
Sound fluctuation.
Cannot remove the tape.
Possible cause
Is the erase-protection tab removed?
Is it a normal tape?
(You cannot record on a metal or CrO
2
tape.)
Is there any slack?
Is the tape stretched?
Are the capstans, pinch rollers, or heads
dirty?
If a power failure occurs during playback,
the heads remain engaged with the tape.
Do not open the compartment forcibly.
Wait until electricity resumes.
Remote control
Symptom
The remote control does not operate.
Possible cause
Is the AC power cord of the unit plugged
in?
Is the battery polarity respected?
Are the batteries dead?
Is the distance or angle incorrect?
Does the remote control sensor receive
strong light?
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.
Connecting DVD player
Symptom

Possible cause
Is the power to the DVD player connected properly?
Is a digital signal being output from the
DVD player?
Is “DVD NO” being displayed?
Does the type of DVD digital signal appear in the display?
Since “DVD---” is not output from the
Dolby digital source, it cannot be
decorded.
Is a Dolby digital 2/0 (monaural) signal
being played with the surround mode set
to NORMAL and without a center
speaker connected?
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.
Note:
If neither operation above restores the unit, clear all the memory by resetting it.

• Adjustment
Since this CD system incorporates the following automatic
adjustment functions, readjustment is not needed when
replacing the pickup. Therefore, different PWBs and pickups
can be combined freely.
Each time a disc is changed, these adjustments are
performed automatically. Therefore, playback of each disc
can be performed under optimum conditions.
