TUNING
VOL control
Try the above steps 3 and 5 until the
receiving performance becomes better.
Auto power on/off function
When you remove the headphones from your
head, the power turns off automatically. Do not
allow the self adjusting band to be pulled up,
otherwise the headphones will be switched on.

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
Notes:
1. Use a transmitter to which check and adjustment are already
completed.
2.
On adjusting the headphones section, use the transmitter as a jig.
Headphones:MDR-RF875R

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.

Transmission Frequency Check
1. 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 frequenc y counter, then measure the frequencies of CH1, CH2 and CH3 and make sure the
values are as follows:
CH1 : 863.5 MHz ± 40 kHz
CH2 : 864.0 MHz ± 40 kHz
CH3 : 864.5 MHz ± 40 kHz
Pilot Signal and MPX Signal Modulation Check and
Adjustment
1. Set the channel to CH2.
2. No signal input (The operating time in this case is limited to 4
or 5 minutes.)
3. See the RV402 and RV403 to max. (clockwise)
4. Connect a digital voltmeter (A C range) to the movable terminal
of RV403 (Fig.2).
5. Adjust the value of the digital voltmeter to minimum b y R V401.
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 1.7 mVrms ± 0.1
mV 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 2.5 mVrms ± 0.2
mV by RV402.

When the frequency does not satisfy the specified value, exchange the vco unit. When completed with replacement, recheck
the frequecies of CH1, CH2 and CH3.
Compresser Output Check
1. 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 confirm the value is

4. Input a signal of 1 kHz, 31.6 mVtms to L-CH and R-CH of J402.
5. Measure IC 601 pin 7 and IC 602 pin 7 on the CHG-NR board
using a digital voltmeter (AC range) and confirm the value is
31.6 mVrms ± 5 mV (Fig.1).
6. When the frequency is not satisfied the specified v alue, exchange
TX- BASE board or CHG-NR board.
