Check the

②

hatch, whether it is deformed. As well as the track, whether it

consist dirt. Maintain them when necessary.

Check hatch

③

track, whether it is too dusty, which results mechanism

stuck. Clean and lubricate when necessary.

button, whether it is cracked or dropped from loader. Replace radio
assembly when necessary.

Loader stuck or damaged

Press hatch popup button, inspect the operating condition of hatch

link mechanism and loader. Remove radio cover, press popup button
and indicate the malfunction position. Replace radio assembly when
necessary.

No. 209 Cassette speed abnormal, turned over automatically and chewed

Malfunction Cause

Solution

Power supply malfu

①

nction

Check external power supply, whether the voltage is over load and

①
results inner appliances operating unstably. The normal value shal
between 12V and 14V approximately.

Sentus or deformation on

②
cassette housing

Sentus or deformation on cassett

②

e housing affects cassette

operating and results low speed, unstably or chewed. Check and
replace the cassette.

Button switch not in place

③

Button switch not in place, resulting all the link mechanism

③
operating unreliably, and further causes cassette speed unstably or
chewed. Check operating conditions of all buttons and link
mechanism, and implement modification.

Drive gear worn

④

Drive gear worn seriously, resulting clearance increased between

④
each gear, and further causes speed differential. As a result the
cassette speed becomes abnormal, and may turn over automatically
or chewed. Replace recorder assembly.

Drive belt skid or dropped

⑤

Drive belt skid or dropped, that is, the friction reduced between belt

⑤
and motor/flywheel, which results motor speed lowered and unstably.
Check drive belt, whether it is loose or dropped, and replace recorder
assembly when necessary.

Drive motor brush worn seriously.

⑥

Drive motor brush worn seriously and fallen graphite powder results

⑥
partly short circuit between the copper plates of commutator, and
further causes motor speed lowered. Check the clearance and
wearing condition between brushes, and replace recorder assembly
when necessary.

Guide pulley low pressure or

⑦
deformed

Guide pulley low pressure or d

⑦

eformed, wearing or poor bearing

lubrication will cause cassette speed lowered and unstably. Check
guide pulley wearing and operating condition, and lubricate or replace
recorder assembly when necessary.

Speed regulator potentiometer of

⑧
electric governor damaged

The resistance of speed regulator potentiometer, electric governor,

⑧
increased or decreased, as well as delayed diode open circuit or short
circuit will result motor voltage raised or reduced, which causes motor
speed unstable. Check the speed regulator potentiometer of electric
governor circuit, whether it is damaged, and replace recorder
assembly when necessary.
