Display (LCD)

Bar graph, receive mode: Normally acts

as an S-meter. If C W T is turned on, the
right half of the S-meter becomes a tuning
aid.

Bar graph, transmit mode: Normally
shows SW R and R F output. In voice and
data modes, the bar graph shows CM P
(compression) and AL C whenever mic
gain or compression are adjusted.

VFO Icons: Shows that a VFO is locked.
The TX icon points to the transmit VFO:

A

VFO A is the transmit VFO

Filter Passband Graphic: Shows

location of receive passband

Filter Icons:

NT C H Notch filtering on (N T C H)

I / II PBT filter function (I/ I I)

XFI L Extended filtering (FL1 -F L 5 )

Mode Icons

Basic modes (LSB or U S B, C W , D AT A , A M , or

FM ) are selected by tapping M O D E . Alternate modes

(CW R EV, D A T A R E V, A M- S, F M +/- ) are
selected by holding AL T . LS B and U SB are alternates
of each other. In SSB mode the + icon indicates
ESSB. T indicates FM/tone, CW/DATA text decode,
or AM-Sync auto-tracking.
