1. Pull out the two connectors (CN18 and CN19) from the sine wave (Max.)
Control Amplifier P.C.Board.
2. Connect an audio signal generator, a SCA signal generator,
and an attenuator to the connector pins (CN18 and CN19)
and then, connect a VTVM and a synchroscope across
Resistor R515 on the Control Amplifier P.C.Board as
illustrated.

4. Feed the modulated signal at 1mV(—60dB) to the
connector pin (CN18) with the unit in the playback mode.

TRANSMITTED FREQUENCY ADJUSTMENT
1. Connect a frequency counter through a 47 k-ohm resistor to
the emitter of Transistor Q2 as illustrated.
Frequency Counter
570 Hz (+3 Hz)
4. Adjust the potentiometer (P3) to obtain 38 kHz (+0.2 kHz)
on the frequency counter. Then, turn the core of the
transformer (T1) until the wave form becomes the
maximum at peak-to-peak (50 — 55 V) on the synchroscope
(Volt. Range: 10V/cm.).
5. Check to see that the frequency counter reads 38 kHz
(£0.2 kHz).
* If not, repeat the adjustment in Item 3 until the specified
value is obtained.
6. Connect the synchroscope (Volt. Range: 0.2V/cm) to the
plus side of Capacitor C6 as illustrated. Then, adjust the
potentiometer (P2) until the synchroscope reading becomes
1 V at peak-to-peak.

2. Turn the potentiometer (P2) fully counter-clockwise and
adjust the potentiometer (P1) by turning it until the
