Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

MECHANICAL ADJUSTMENTS
Tape Tension Measurement
1. Clean the following parts with a denatured-alcohol-moistened
swab:
record/playback head pinch roller
erase head rubber belt
capstan
2. Demagnetize the record/playback head with a head demagne-
tizer. (Do not bring the head demagnetizer close to the erase
head.)
3. Do not use a magnetized screwdriver for the adjustments.
4. After the adjustments, apply suitable locking compound to the
parts adjusted.
5. The adjustments should be performed with the rated power
supply voltage (2.5 V) unless otherwise noted.

ELECTRICAL ADJUSTMENTS
Tape Speed Adjustment
Mode: playback
Procedure:
1. Set [REC˚TIME]switch (S902) to NORMAL (4.8 cm/s) posi-
tion, and playback the tape (WS-48A) .
2. Adjust RV601 so that frequency counter reading becomes 3,000
Hz.
Specification values: 2,990 to 3,010 Hz
3. Set [REC˚TIME]switch (S902) to DOUBLE (2.4 cm/s) posi-
tion.
4. Playback the tape from the beginning for two minutes, then
adjust RV602 so that frequency counter reading becomes 1,500
Hz.
Specification values: 1,495 to 1,505 Hz
Confirm that deflection of the frequency counter reading between
the beginning and the end of tape is within 2% (NORMAL: approx.
60 Hz, DOUBLE: approx. 30 Hz) .
Setting:
• Supplied voltage: 2.5 V
• Switch and control position
VOL contorl (RV101) : mechanical center
PAUSE switch (S601) : OFF
SPEED CONTROL (RV603): center click
