^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 signal's audio response.
The filtering frequency is adjusted to effectively eliminate un-
wanted tones via the DSP circuit.
^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. 12-13)
^9 SPLIT SWITCH [SPLIT] (p. 6-6)
➥ Turns the split function ON and OFF when
pushed.
➥ Turns the split function ON, equalizes the sub
readout frequency to the main readout and sets
the sub readout for frequency input when pushed
for 1 sec. in non-FM modes.
• The offset frequency is shifted from the main readout
frequency in FM mode. (p. 12-14)
• The quick split function can be turned OFF using set
mode. (p. 12-14)
➥ Turns the split function ON and shifts the sub
readout frequency after inputting an offset.
&0 MAIN BAND ACCESS SWITCH [MAIN]
Selects access to 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 sig-
nal with interference, the automatic tuning func-
tion may not be tuned, or tuned into an undesired
signal.
Changes the displayed frequency (main band), se-
lects set mode setting, etc.
Switches the frequency and selected memory
channel 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 access to 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.
