XPLANATION OF THE
[ 3/5 ]( ATT ) "Attenuator"
By pressing this key, the attenuation can be
switched as shown below. The noise level on the
band will vary according to conditions, your an-
tenna, the time of day, etc.; please select the ap-
propriate value for current conditions.
0 dB 10 dB 20 dB
[ 4/7 ]( A/B )
Selects the VFO which is to be shown.
In the case of "Single" display, the Main (VFO-A)
and Sub (VFO-B) VFOs can be toggled alternately.
The selected VFO frequency is shown by line (the
other VFO frequency is shown by a dashed line).
In the "Dual" mode, both VFO's will be shown.The
selected VFO frequency is surrounded by a box.
Advice: In the case of the Contest version, the
[ RX ] switch to the left of the [ CLAR/VFO-B ] knob
will, when pushed, cause both the VFO itself and
the Spectrum Scope display to change to VFO-
B. Additionally, when the optional RXU-9000 Dual
Receive Unit is installed, you may use the
[ 4/7 ]( A/B ) key to make this change, just like on
the MP version.
[ 5/10 ]( DUAL )
This key switches between Single and Dual VFO
Spectrum Scope display. When Dual is selected,
the Main VFO will occupy the upper position, and
the Sub VFO the lower.
When this key is pressed once more, the radio will
revert to "Single" display. If you want to change
the setup of a Spectrum Scope VFO, press the
[ 4/7 ]( A/B ) key. In this case, the frame will move to
the upper side or lower side. Select the side which
you want to change, then press the [ 3/5 ]( ATT ) key
or the [ 2/3.5 ]( SPAN ) key to change those respec-
tive settings just for the selected VFO.
In the Dual display mode, when you want to con-
firm the setup situation, press the [ 6/14 ]( STATUS )
key to show the current settings for that screen.
Press the key once again to make the setup
screen disappear.
Press the [ MNU ] key momentarily to enter the
Menu mode. Select the item which you want to
change by rotating the Main Tuning knob (in this
case, the item will be one of the items in the range
from "SCOPE 112 MAIN FIX 1.8 MHz" to "SCOPE
133 SUB FIX 50MHz"). Then change the setting
by rotating the [ CLAR/VFO-B ] knob.
When the change is completed, press and hold
in the [ MNU ] key for 2 seconds to save the change.

Advice: In the Contest version, if the optional
RXU-9000 dual Receive Unit is installed, you may
also choose the "Dual" A/B VFO split Spectrum
Scope display, just like on the MP version.
[ 6/14 ]( CTR/FIX )
By pressing this key, it is possible to switch be-
tween the CTR mode and FIX mode.
In the CTR mode, the current operating frequency
is displayed at the center of the screen; in the
FIX mode, the frequency selected via the Menu
is fixed at the left edge of the display.
[ 7/18 ]( LBWS )
Press this key to activate the "Limited Band Width
Sweep" (LBWS) function, which permits high-
speed sweeping of a band segment.
LBWS-1 ( 50% )
NORMAL
LBWS-2 ( 30% )
As the bandwidth is set narrower, the sweep
speed becomes faster, allowing the scope to cap-
ture signals with quicker resolution. The band-
width can be set to 50 %, 30 % or 10 % of the full
span. The sweep speed becomes faster by the
following amounts:
50 %: about 2 times faster
30 %: about 3 times faster
10 %: about 10 times faster
Advice: When you enter the LBWS mode, the
function keys below the Display change.
It is possible to move the sweep position by press-
ing the [ 5/10 ]( ) and [ 6/14 ]( ) key.
If you want to return to normal operation, press
[ 6/14 ]( LBWS ) key as needed.
Please note that LBWS can not be used in the FIX
mode. Please use LBWS only in the CTR mode.

and they are grouped for easy recognition; the
group name is displayed at the top left corner of
the list screen. It is usually more convenient if
you initially select the group by rotating the Main
Dial, and then select the item you want.
