q TUNING STEP KEY
➥ Push to turn the Quick tuning function ON or
OFF.
• "√" appears above the 1 kHz icon when the Quick
tuning function is turned ON and the frequency is
changed in 'kHz' steps.
➥ "√" appears when the Quick tuning function is
turned ON. Hold down for 1 second to enter tun-
ing step Set mode.
After selecting a step, push again to return to nor-
mal operation.
• 0.1, 1, 5, 9 and 10 kHz tuning steps are selectable.
➥ While the Quick tuning function is turned OFF,
hold down for 1 second to turn the 1 Hz step ON
or OFF.
• 1 Hz indication appears, and the frequency is changed
in 1 Hz steps.
w NOISE BLANKER KEY
➥ Push to turn the noise blanker function ON or
OFF.
• "
" appears when the noise blanker function is
ON.
➥ Hold down for 1 second to enter the noise blank-
er Set mode. Rotate [M-CH] to select, then rotate
[DIAL] to set the noise blanker level and blank width;
push again to return to normal operation.
• When entering the noise blanker Set mode, the noise
blanker function is automatically turned ON.
4 What is the noise blanker?
The noise blanker reduces pulse-type noise such
as that generated by automobile ignition systems.
This function is not effective against non pulse-type
noise.

➥ Hold down for 1 second to enter the noise reduc-
tion level Set mode. Rotate [DIAL] to set the NR
level; push again to return to normal operation.

noise reduction function is automatically turned ON.
4 What is the Noise Reduction function?
The Noise Reduction (NR) function removes random
noise from the receiver passband. The level is adjust-
able to allow maximum clarity without harming the
intelligibility of the desired signal. Noise Reduction
should generally not be used in the digital modes.
r ANF/METER KEY
➥  P ush to turn the Automatic Notch Filter function
ON or OFF in the SSB and AM modes.
• "
" appears when the automatic notch filter func-
tion is ON.
➥ Hold down for 1 second to toggle the meter func-
tion.
PO ➟ SWR ➟ ALC
• PO
: Displays the relative RF output power.
• SWR : Displays the SWR of the antenna. (p. 19)
• ALC
: Displays ALC level. (p. 19)
4 What is the Automatic Notch Filter?
The Automatic Notch Filter is a narrow DSP filter that
automatically identifies and attenuates beat tones, tun-
ing signals, CW, and so on, even if they are moving. It
removes them from the receiver passband while pre-
serving the desired signal's audio frequency response.
