Notes on chip component replacement

•Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be damaged by heat.

Flexible Circuit Board Repairing

•Keep the temperature of soldering iron around 270˚C during 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.

Unleaded solder

Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40°C higher than

ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350°C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful!

• Strong viscosity

Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.

• Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

SECTION 1

SERVICE NOTE

In this set, record/play mode is detected using the switch S704 (TAPE POWER). S704 is mounted on the MAIN board. If MAIN board is removed, it becomes impossible to detect record/play mode. Where MAIN board is removed, when you measure operation and voltage of each part of the mechanism deck, please turn on S704.

Tape Speed Adjustment

Procedure:

Test tape

WS-48A

(3kHz, 0dB)

1. Enter the FWD playback mode.

2. Adjust RV601 so that the value of the frequency counter reading

becomes 3,000 Hz. Specification value:

Frequency counter 2,985 Hz – 3,015 Hz

3. Check that the frequency deviation at the beginning and ending

of a tape is within 1.5 % (45 Hz).
