Press the TUNE button briefly for
automatic tuning of the headphones.
If you do not receive a clear audio
signal, press it again.
Do not pull up the self-adjusting band when not
in use, as this will consume the battery power.

Flexible Circuit Board Repairing
• Keep the temperature of the 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

6. Set the RV303 (TUNE) to the center position.
7. Connect an oscilloscope CH1 and CH2 to IC301 pin 6 and
pin 4.
8. Check the waveform of the oscilloscope to CH1 is demodulated
1kHz signal and CH2 is GND.
9. If CH1 and CH2 are not satisfied in step 8, adjust the coil
(L301) on the RX board to satisfied step 8.
10. Set the transmitter CHANNEL switch to 1.
11. Adjust the RV303 (TUNE) to receive a signal.
Confirm the signal with stereo.

Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or
less are not indicated except for electrolytics and tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise specified.
• A : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 2.4V and fed with regulated dc power supply
from external power voltage jack.
• Voltages and waveforms are dc with respect to ground under nosignal (detuned) conditions.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tolerances.
• Signal path.
