2-1. Front Panel
1. VOL/POWER
Power ON-OFF switch and volume control are combined. Turning the control fully counter clockwise will turn
the power OFF. Clockwise rotation will increase the volume. In the power OFF position, about 2.5mA current is drawn
to back-up the micro-computer, provided the power cable is connected to a constant power source. To completely disable
the transceiver, disconnect the power cable.
2. SQUELCH
The squelch control is used to eliminate noise during no-signal time. Normally, this control is adjusted clockwise
until the noise disappears and the BUSY indicator goes off (threshold level). For scan operation, this control must be set
to the threshold point.
3. TX Shift Indicator
+ (RED): By pressing the GD key on the keyboard (11). the indicator will light, indicating that transmit
frequency is switched up 600 kHz from the receive frequency. (Refer to the item FH key)
S (YELLOW): By pressing the S key on the keyboard #(11). the indicator will light, indicating that the
transceiver is operating in the simplex mode. (Refer to the item S key)
— (RED): by pressing the - key on the keyboard #(11). the indicator will light, indicating that transmit
frequency is switched down 600 kHz from the receive frequency. (Refer to the item - key)
