To operate, hold the mic PTT switch depressed until keys are started operating.
Note:
1. When the tone encoder is started operating, the transceiver is in transmit s>
mode even with the PTT switch released.
2. More than about 0.8 seconds keying interval restores the transmit mode
to receive mode.
3. The touch-tone encoder level can be readjusted according to your re-
quirement.
When readjusting, set the deviation to 3 kHz by the mic built-in VR with
both the 3 and 6 keys of the encoder held depressed. Next, hold both the
2 and 3 keys depressed to verify the deviation which is within
1.2 kHz+0.3 kHz.
When operating, the beep sounds to indicate operation. Beep level can be ad-
justed by the potentiometer inside. (page 18)
