is received.
Lights red when transmitting.

MEMORY BANK CONTROL [BANK]
❍
When both the PBT and RIT LEDs are OFF
Rotate to select a Memory bank.
❍
When the PBT LED (
y
) lights green
(Mode: SSB/CW/RTTY/AM)
Rotate to adjust the receiver’s IF filter passband
width using the DSP circuit.
❍
When the RIT LED (
u
) lights orange
Disable this control.
t
M-CH CONTROL•CLEAR SWITCH [M-CH]•[CLR]
Push to select the action of the [M-CH/BANK] con-
trols as the Memory/Bank selection, PBT control or
RIT control.
❍
When the both RIT and PBT LEDs are OFF
Rotate to select a Memory channel.
❍
When the RIT LED lights orange
➥
Rotate to adjust the RIT frequency shift.
• The frequency shift range is ±9.99 kHz in 10 Hz
steps. The control tunes in 1 Hz steps when the op-
erating frequency readout is set to the 1 Hz step.
➥
Hold down for 1 second to clear the RIT shift
frequency.
✔
What is the RIT function?
The RIT (Receiver Incremental Tuning) shifts the re-
ceive frequency without shifting the transmit frequency.
This is useful for fine tuning stations calling you off-fre-
quency, or when you prefer to listen to slightly different-
sounding voice characteristics.
❍
When the PBT LED lights green
(Mode: SSB/CW/RTTY/AM)
➥
Rotate to adjust the receiver’s IF filter pass-
band width using the DSP circuit.
➥
Hold down for 1 second to reset the PBT set-
tings.
• The PBT is adjustable in 50 Hz steps in the SSB/
CW/RTTY modes, and 200 Hz in the AM mode. At
that time, the shift value changes in 25 Hz steps in
the SSB/CW/RTTY modes, and 100 Hz in the AM
mode.
• The PBT controls function as an IF shift control.
✔
What is the PBT control?
The PBT function electronically modifies the IF pass-
band width to reject interference. This transceiver uses
the DSP circuit for the PBT function.
y
PBT LED
Lights green when the [M-CH/BANK] controls act
as the PBT control.
• Push the [M-CH]
switch to select PBT control.
u
RIT LED
Lights orange when the RIT function is turned ON.
➥
Lights orange when the [M-CH/BANK]
➥
controls
act as the RIT control.
• Push the [M-CH]
switch to select RIT control.
•
The RIT control is the inner control. The outer control
is disabled.
i
RIT KEY
RIT
(FM sec. 5)
Push to turn the RIT function ON or OFF.
➥
• Use the [M-CH]
control to vary the RIT frequency.
➥
Hold down for 1 second to add the shift frequency
of the RIT function to, or subtract it from, the dis-
played frequency.
o
ANTENNA TUNER/CALL KEY
TUNER/CALL
❍
ANTENNA TUNER KEY Operation (FM sec. 16)
(Frequency band: HF/50 MHz)
➥
Push to turn an optional automatic antenna
tuner ON or OFF (bypass).
➥
Hold down for 1 second to manually tune the
antenna tuner.
• If the tuner cannot tune the antenna within 20 sec
-
onds, the tuning circuit is automatically bypassed.
❍
CALL KEY Operation (FM sec. 11)
(Frequency band: 144/430 MHz)
Push to select the Call channel.
In the 70 MHz band, push to sound an error beep.

MENU KEY
MENU
(p. 1-10)
Push to change the set of functions assigned to the
touch keys.
• Toggles the function display menu between M-1, M-2 and
M-3 menus or D-1 and D-2 menus.

MIC GAIN/RF POWER ADJUSTMENT KEY
MIC/RF PWR
(p. 3-24)
Push to open the MIC gain/RF power adjustment
display.
• Rotate [M-CH]
to adjust the MIC gain.
• Rotate [BANK]
to adjust the RF power.
