Troubleshooting Specifications
Basic troubleshooting of a cassette tape deck is similar to
troubleshooting of any other electrical or electronic equipment.
Always check the most obvious possible causes first. To give
you a few ideas of what to look for, check the following:
No power
® Is the power cord connected?
The deck starts to play suddenly
® Set the TIMER switch to OFF.
No audio output
® Check the connections to the stereo system.
Low sound quality
® If the heads are dirty or magnetized, clean/demagnetize the
heads.
® Has the correct NR System been selected?
Strange Sound
® Set the PITCH CONTROL knob to the center
(
normal
speed).
Impossible to enter the record mode
® If the record protection tabs of the cassette tape are
broken off, cover the hole with adhesive tape.
® Turn the REC LEVEL knob to the right.
Remote control unit operation is impossible.
® Press the power switch of the main unit.
® Insert or change the batteries of the remote control unit.
