a) Speaker: ON
b) Squelch: OFF
c) AGC:

Transmitter
1. On each band, confirm that the antenna is automatically tuned when the [LOG/TUNE]
key is pressed. Automatic tuning time of the antenna should take no longer than 15
seconds to tune, recheck antenna length.
2. Communicate with the handset, confirming that antenna current (IA) changes with voice
level.
3.2 Manual 2182 kHz Tuning Preset
For safety measure, it is required that 2182 kHz be tunable both automatically and manually.
The setup to enable manual tuning, in the event the antenna tuner system fails, is made
with the DIP switches in the antenna coupler. Call a coast station and tell your situation. Be
sure not to transmit during silent period (00 to 03 min. 30 to 33 min. of every hour).
1. Remove the top cover of the antenna coupler. Set the S1 switch (Coupler Board) to
AUTO.
