@ SUB BAND SWITCH [SUB] (p. 19)
Activates the sub band access function to control
the sub band's frequency/mode while standing by
on the main band.
- "SUB" appears in the function display while the func-
tion is in use.
"SUB" appears.
@ SSB/CW MODE SWITCH [SSB/CW-Ts]
(pgs. 17, 18)
e Selects USB, LSB, CW or CW-Narrow*
mode in sequence.
* Selectable only when the main band is se-
lected. When an optional CW narrow filter is
not installed, no audio is output in CW-N.
e Indicates accessed band's tuning step in-
then ~~ crements after pushing [FUNC]; use the
tuning dial to change the tuning steps.
(p. 21)
- Tuning steps can be separately selected for
FM and SSB/CW.
FM :0.1, 5, 10, 12.5, 20, 25, 100 kHz
SSB/CW : 1, 10, 50, 100 Hz
@) FM MODE SWITCH [FM/RPT-DUP] (pgs. 17, 27)
e Selects an FM mode.
- FM mode with a duplex/subaudible tone en-
coder setting is selected when pushing twice
on the main band (U.S.A. and Australia versions).
® Selects —duplex, +duplex or cancel the
ah duplex (simplex) on the main band in se-
ma = quence after pushing [FUNC]. (p. 27)
- An auto-repeater function is available to acti-
vate duplex and the tone encoder automat-
ically when in a repeater frequency range
(U.S.A. and Australia versions).

@ MIC GAIN CONTROL [MIC] (p. 25)
Adjusts microphone input gain.
- Adjust the [MIC] contro! so the [TX] indicator brightly
iluminates (ALC activates) periodically during normal
voice transmission.

AY e Turns the RIT function ON and OFF.
-Use the [RIT] control to vary the RIT
frequency.

pushed in the satellite mode. (p. 34)
FUNCTION
The RIT (Receiver Incremental Tuning) shifts the receive
frequency without shifting the transmit frequency.
This is useful for fine tuning stations calling you on an
off-frequency or when you prefer to listen to slightly
different-sounding voice characteristics, etc.
@ QUICK TUNING SWITCH [kHz/MHzZ] (p. 21)
Selects the 1 kHz or a pre-selected normal
tuning step.
e Selects the 1 MHz tuning step when pushed for
2 sec.
"+x " indicates the selected quick tuning step.
