MODE/SSB/CW
Switch the operating mode.
Press and hold the [MODE] key, then touch the de-
sired operating mode.
Press it briefly to set the previously selected oper-
ating mode.
Pressing the [SSB]/[CW] key repeatedly will toggle
to the alternate mode.
In the LSB or USB mode, pressing the [SSB] key
toggles between "LSB" and "USB" mode.
In the CW-L or CW-U mode, pressing the [CW] key
toggles between "CW-L" and "CW-U" mode.
[SSB] key
USB → LSB → USB →
[CW] key
CW-U → CW-L → CW-U →
When changing modes from SSB to CW, the
display frequency will shift on the dis- play,
even though the actual tone that is heard
does not change.
This shift represents the BFO offset between
the "zero beat" frequency and the audible
CW pitch (tone). The pitch is programmed
via Menu item "CW FREQ DISPLAY" page
94).
BK-IN
This key turns the CW break-in capability ON or
OFF. While CW break-in is activated, the LED in-
side this key glows orange.

MONI
Use the Monitor feature to listen to the quality of
your transmitted signal. While activated, the LED
inside this key glows orange.
1. Press the [MONI] key.
Monitor feature is activated.
When transmitting, the audio (side tone when in
CW operation) is heard from the speaker.
2. Press and hold the [MONI] key and adjust the
Monitor level with the [MULTI] knob.
Transmit audio monitor is not activate in the
FM, DATA-FM and D-FM-N modes.
● If you are using the speaker for monitoring,
instead of headphones, excessive advancement
of the Monitor level can cause feedback to occur.
Additionally, this feedback can cause the VOX
system to hang up in a loop, making it impossible
to return to receive. Therefore, we recommend
the use of headphones, if at all possible, or the
minimum usable setting of the Monitor level, if the
speaker must be used.
3. To switch the Monitor OFF again, press the
[MONI] key once more.
● Because the Monitor feature samples the trans-
mitter IF signal, it can be very useful for checking
the adjustment of the Speech Processor or Para-
metric Equalizer on SSB, and for checking the
general signal quality on AM.
SYNC
Change the frequency of the MAIN band with the
MAIN dial, the frequency of the SUB band also
changes in the same step. If you press and hold for
a while, the SUB band frequency will be the same
as the MAIN band.
When this key is pressed and held, the frequency
of the SUB band becomes the same frequency as
the MAIN band.
