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.

CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Laser Diode Properites

• Material: GaAlAs

• Wavelength: 780 nm

• Emission Duration: continuous

ELECTRICAL ADJUSTMENTS

TEST MODE

This set have the test mode function. In the test mode, FM Auto Scan/Stop Level and MW Auto Scan/Stop Level adjustments can be performed easier than it in ordinary procedure.

1. Set the “power select” switch (S700) is “A (ON) ” position.

2. Turn ON the regulated power supply. (All LEDs on the set lights up, and the clock is displayed.)

Note:

Press the [OFF] button, if the clock is not displayed.

3. Push the preset [4] button.

4. Push the preset

5. Press the preset

[5] button.

[1] button for more than two seconds.

6. Then the display indicates all lights, the test mode is set.

1. Push the

[OFF] button.

2. Return the “power select” switch (S700) to initially set position.

See the adjustment location from on page 16 for the adjustment.

MD SECTION

MD section adjustments are done automatically in this set.

TUNER SECTION

Cautions during repair

When the tuner unit is defective, replace it by a new one because its internal block is difficult to repair.

Note:

Adjust the tuner section in the sequence shown below.

1. FM Auto Scan/Stop Level Adjustment.

2. FM Stereo Separation Adjustment.

3. MW Auto Scan/stop Level Adjustment.

4. RDS S-Meter Adjustment.
