Automaticstop
When the cassette comes to its end in PLAY or RECORD modes, the built-in automatic stop system
ensures that the PLAY or RECORD buttons pressed down are released. This system works whether a
RADIO or CD program is being recorded. Only the Cassette function is automatically stopped, the
RADIOorCDplayercontinuestooperate.
Typesofcassettes
Only use good quality IEC TYPE 1 cassettes for making recordings.The system can read other type of
cassettes, but it cannot make good quality recordings onto these more specialized tapes. The use of
C120cassettesisnotrecommendedwiththistapedeck.
Protectingrecordings
Normally,everythingpresentonthetapeisautomaticallyerasedwhenanewrecordingismadeoverit.
You can however protect your recordings against accidental erasure by removing the
tabslocatedontherearofthecassette.
A
SIDE A
When the cassette is held with the recorded side up and the
exposed tape facing forward, the corresponding protection tab is
the one located on the left rear of the cassette. All pre-recorded
cassettes are protected in this way against accidental erasure of
the commercial recordings that they contain. “Protected”
cassettes will not allow you to press the Record button. It you
attempt to make a recording and find it impossible to press this
button down, never force the mechanism for this may cause
damage to it. Ensure that a cassette has been loaded and that its
protection tab has not been removed. It is possible to record on a
cassette after its protection tabs have been removed by covering
theopenslotswithapieceofselfadhesivetape.
Maintainingthecassettetapemechanism
Carefully clean the heads and the pinch roller/capstan assembly after every ten hours of use so as to
remove all traces of oxide deposits. Various maintenance products specifically designed for cassette
decksareavailableonthemarket.
The erase and record/play heads as well as the pinch roller surface are delicate components that must
absolutely not come into contact with metal objects such as screwdrivers. You will find it easier to clean
thecompleteassemblybypressingthePLAYbuttonso as to raise theheads and thepressure roller into
clearsight.NeverforgettopresstheCASS.STOPbuttonaftercleaningthemechanism.Thepinchroller
may become damaged if the deck is left in play mode after powering down. Never attempt to lubricate
anyofthepartsinthissystem.

"Neverinterferewiththenormalventilationprovidedforthissystemwheninnormaluse".
Troubleshooting:
If you encounter a problem with your system, first check the possible solutions described in the table
below before seeking help from a service center. If you cannot solve the problem by following these
instructions or if the system has suffered physical damage, contact a qualified person such as your
dealer,forservicing.
SYMPTOM POSSIBLE CAUSE SOLUTION
No sound. Incorrect or loose connections.
Volume knob not turned up. Check all of the connections and correct them where
necessary. Turn the volume
knob up.
Bad radio reception. The built-in AM loop antenna is
not correctly positioned. The
FM wire antenna is not
correctly deployed and
positioned.
In AM mode only, change the
system's position and
orientation. Deploy the FM
wire antenna in the position that
offers best reception.
Cannot record to a cassette. The cassette's protection tab has
been broken off. Replace the tab with a piece of self adhesive tape.
The recorded sound is not
very clear when played. The record/play head is dirty. Clean and demagnetize the record/play head.
Excessive tape wow, flutter
or sound skips. The capstan and pinch roller are dirty. Clean the capstan and the pinch roller.
Incomplete tape erasure. The erase head is magnetically
charged. Demagnetize the erase head.
Cannot read a CD. The disc is dirty. The disc is
upside down. The CD player is
in Pause.
Clean or replace the disc. Turn
it over so that the label faces
up. Release the Pause mode.
Cannot use the remote
control. There is an obstacle blocking the signal between the remote
control and the sensor on the
system. The batteries are too
weak.
Remove any obstacle. Replace
the batteries.
None of the functions work. The microprocessor has been
affected by outside electrical
interference.
Switch off the system for a few
minutes, then switch it back on
again.
