[( VFO-A ) RX ] Indicator/Switch
Press this button to activate receive on the VFO-A
frequency. The LED inside the button will glow
green when the transceiver is receiving on the VFO-
A frequency.
When the transceiver receives the VFO-A frequency,
pressing this button momentarily will mute the re-
ceiver, and the indicator will blink. Pressing the but-
ton once more will restore receiver operation, and
the indicator will glow green steadily.
[( VFO-A ) TX ] Indicator/Switch
When this button is pushed, the LED inside the
button will glow red; and, when the PTT switch is
pressed, the transceiver will transmit on the VFO-A
frequency (subject to any Clarifier offset, of course).

If this indicator is not illuminated, it means the
[( VFO-B ) TX ] Indicator/Switch has been selected (it
will be glowing red). In this case, transmission will be
on the frequency and mode programmed for VFO-B.
[ STO ] (Store) Button
Pressing the [ STO ] button copies the contents (fre-
quency, mode, bandwidth, FM repeater offset, and
CTCSS settings) of VFO-A, into consecutive QMB
Memories.

You may adjust the bandwidth using the [ WIDTH ]
knob.
In the AM mode, this button is used to toggle the re-
ceiver bandwidth between wide (9 kHz) and narrow
(6 kHz).
In the FM mode on the 28 MHz and 50 MHz bands,
this button is used to toggle the FM deviation/band-
width between wide (±5.0 kHz Dev./25.0 kHz BW)
and narrow (±2.5 kHz Dev./12.5 kHz BW).
[ SPLIT ] Switch
Press this button to operate split frequency between
VFO-A (used for reception) and VFO-B (used for
transmission). If you press and hold in the [ SPLIT ]
button for one second, the "Quick Split" feature will
be engaged. VFO-B transmit will automatically be
set to a frequency 5 kHz higher than the VFO-A re-
ceive frequency, with the same operating mode. The
transceiver will operate in the Split mode.
[ TXW ] ( TX Watch ) Switch
Pressing and holding this button lets you monitor the
transmit frequency when split frequency operation is
engaged. Release the button to return to normal split
frequency operation.
