SECTION 1GENERAL

This section is extracted frominstruction manual.

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.

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.

ELECTRICAL ADJUSTMENTS

Transmission Frequency Check1. Set the noise filter SW to OFF.2. Input a signal of 1 kHz, 40 mVrms to only the L-CH (J402).3. Connect a telescopic antenna to the frequency counter input

and extend the antenna to a length of approximately 8 cm.4. Place TX-BASE board close to the frequency counter, then

measure the frequencies of CH1, CH2 and CH3 and makesure the values are as follows:

CH1 : 913.5 MHz ± 200 kHzCH2 : 914.0 MHz ± 200 kHzCH3 : 914.5 MHz ± 200 kHz

When the frequency does not satisfy the specified value,set the channel switch (S402) to CH2, then adjust the value ofthe frequency counter to 914.0 MHz by trimmer capacitor inthe VCO unit.

Standard value :913.9MHz to 914.1MHz.

When completed with replacement, recheck the frequecies ofCH1, CH2 and CH3.

Compresser Output Check1. Set the channel to CH2.2. Input a signal of 1 kHz, 316 mVrms to L-CH and R-CH of

J402.3. Measure IC 601 pin 7 and IC 602 pin 7 on the CHG-NR

board using a digital voltmeter (AC range) and put down avalue mesured. (Fig.1).

4. Input a signal of 1 kHz, 31.6 mVrms to L-CH and R-CH ofJ402.

5. Measure IC 601 pin 7 and IC 602 pin 7 on the CHG-NRboard using a digital voltmeter (AC range) and put down avalue mesured (Fig.1).Confirm that there is a difference of step 3 and 5 by 10dB±3dB.

6. When the frequency is not satisfied the specified value,exchange TX- BASE board or CHG-NR board.

Setting : Pilot Signal and MPX Signal Modulation Check andAdjustment1. Set the channel to CH2.2. An electric wave is output for 5 or 10 minutes when OFF to ON

a power supply with no signal input (Power indicator will ON).3. Set the RV402 and RV403 to max. (clockwise)4. Connect a digital voltmeter (AC range) to the center terminal

of RV403 (Fig.2).5. Adjust the value of the digital voltmeter to minimum by RV401.6. See the RV402 to minimum. (counter clock wise)7. Adjust the value of the digital voltmeter to max by L407.8. Adjust the value of the digital voltmerter to 2.1to 2.6mVrms

by RV403.9. Connect a digital voltmeter (AC range) with LPF to movable

terminal of RV403 (Fig.2).10. Input a signal of 1 kHz, 316 mVrms to only the L-CH.11. Adjust the value of the digital voltmeter to 5.2 to 6.4 mVrms

by RV402.
