^6 NOTCH SWITCH [NOTCH] (for SUB band; p. 5-19)
^7 NOTCH SWITCH [NOTCH] (for MAIN band; p. 5-19)
➥ Switches the notch function between auto, man-
ual and OFF in SSB and AM modes.
➥ Turns the manual notch function ON and OFF
when pushed in CW, RTTY and PSK31 mode.
➥ Turns the auto notch function ON and OFF when
pushed in FM mode.
• " " appears when auto notch is in use.
• " " appears when manual notch is in use.
➥ Switches the manual notch characteristics
from wide, middle and narrow when pushed for
1 sec.
✔ What is the notch function?
The notch function eliminates unwanted CW or AM carrier
tones while preserving the desired voice signal. The DSP
circuit automatically adjusts the filtering frequency to effec-
tively eliminate unwanted tones.
^8 DUALWATCH SWITCH [DUALWATCH] (p. 5-16)
➥ Turns the dualwatch function ON and OFF when
pushed.
➥ Turns the dualwatch function ON and equalizes
the main/sub readout frequency to the sub/main
readout when pushed for 1 sec.
function)
• The quick dualwatch function can be turned OFF
using set mode. (p. 12-15)
^9 SPLIT SWITCH [SPLIT] (p. 6-6)
➥ Turns the split function ON and OFF when
pushed.
➥ Turns the split function ON. When pushed for
1 sec. in non-FM modes, equalizes the sub read-
out frequency to the main readout and sets the
sub readout for frequency input.
tion)
• The offset frequency is shifted from the main readout
frequency in FM mode. (p. 12-15)
• The quick split function can be turned OFF using set
mode. (p. 12-15)
➥ Turns the split function ON and shifts the sub
readout frequency after inputting an offset.
&0 MAIN BAND ACCESS SWITCH [MAIN]
Selects the main readout.
• The main readout frequency is clearly displayed. The
sub readout functions only during split operation or du-
alwatch.
&1 MAIN/SUB EQUALIZING SWITCH [M=S]
Equalizes the sub readout frequency to the main
readout frequency when pushed for 1 sec.

PANEL DESCRIPTION
(for MAIN band)
(for SUB band)
Turns the automatic tuning function ON and OFF in
CW and AM modes.
IMPORTANT!
When receiving a weak signal, or receiving a signal
with interference, the automatic tuning function may
tune the receiver to an undesired signal.
Changes the displayed frequency (main band), se-
lects set mode setting, etc.
Switches the frequency and selected memory chan-
nel between main and sub readouts when pushed.
• Switches between transmit frequency and receive fre-
quency when the split frequency function is ON. (p. 6-6)
Push to switch the dial lock function ON and OFF.
Selects the sub readout.
• The sub readout frequency is clearly displayed. The
main readout functions only during split operation or du-
alwatch.
Changes the displayed frequency in sub band.
