!
Keep magnets and metallic objects away from the
head. If the head gets magnetized, it will lead to more
noise and loss of high frequencies. The head and all
metallic parts should be got demagnetized after about
50 hours of use.
!
Consult your dealer about demagnetizing the head.
TROUBLE CHECKS
The following trouble checks will help to correct the most
common problems encountered with a cassette player.
Pilot LED does not glow when the set is switched ON.
+
AC mains plug not properly connected to AC socket.
+
Car battery connections reversed.
+
Fuse blown. Check and replace with another of the same
rating.
Hum and noise coming from speakers.
+
Poor quality of microphone or microphone cables.
+
AC mains cable running close to the input cables.
Sound quality poor on Microphone operation.
+
Improper impedance matching between microphone and
unit. Use LOW IMPEDANCE microphones.
+
In case of microphones with selectable impedances,
keep the impedance switch at LOW position.
Set gets very hot during operation
+
Proper ventilation not provided. Keep the set away from
walls in a well ventilated area.
+
Speaker mismatch causing overloading. Check the total
speaker impedance and connect to the proper tap on the
output terminal strip.
The auto stop mechanism activates and the tape stops
just after it is inserted.
+
The tape is completely wound on the right reel (refer
instructions in “Cassette Insertion”).
+
Cassette spools jammed due to deformed cassette shell.
Tape moving but no output.
+
The tape volume control is at minimum.
+
The MIC/TAPE selector switch is at MIC position.
MAINTENANCE
To get long trouble free service, maintenance is essential.
After some use the Head, Capstan, Pinch Roller etc. that
come in contact with the tape, become dirty due to dust or
magnetic material on the tape. Dirty heads cause loss of
high frequencies and the output falls. Dirty capstan and
pinch roller will cause unstable tape speed, leading to
increased Wow and Flutter.
• Precautions, Maintenance & Trouble Checks
To clean these, follow the under-mentioned procedure:
!
Remove the plastic cover on the top by unscrewing the
screws provided. The head and pinch roller become
accessible through the cutout provided.
!
Clean the head and pinch roller with a cotton bud
dipped in methylated spiri t / alcohol.
PRECAUTIONS
1. Do not use this unit in high ambient temperature.
2. Before the cassette tape is inserted into the cassette
slot, loose tape must be tightened up to avoid its
entangling with the pinch roller.
3. Speaker impedance mismatch may cause insufficient
output or overheating of the components, which may
lead to failure of the components. Check and make sure
that the impedance of the speakers is equal to or greater
than the selected impedance on the output terminal
strip.
4. Use of C-120 cassette is not recommended as it is
extremely thin and may cause problems.
