RIT/XIT and CLR
Tap [RIT] to turn on Receive Incremental Tuning, then rotate the OFS
(offset) knob below the switch to tune in a signal. RIT offsets only your
receive frequency, not transmit. It is especially helpful when CW
stations call you off-frequency.
Similarly, [XIT] can be turned on to adjust only your transmit
frequency. One use for XIT is to quickly move the VFO off-frequency
for doing ATU tuning. This avoids causing QRM (interference) to other
stations.
Tap [CLR] to set the RIT/XIT offset frequency to zero.
You can also left-click a mouse on the RIT or XIT icons to turn them
on/off; a right click turns XIT on/off.

PF1-PF4
[PF1]-[PF4] are user-programmable function switches, primarily used
to quickly access often-used menu entries. For example, by default
holding [PF1] takes you directly to MENU:LCD Brightness. PF1-PF4
menu assignments can be changed by locating a menu entry of
interest, then hold the desired PFn switch.
If the menu parameter assigned to a switch is binary (i.e., has only two
settings), then holding the PFn switch will not bring up the menu.
Instead, it will select the alternate value, then flash a brief message to
display it.
Each of these switches can, alternatively, perform nearly any
combination of radio functions. See MACRO PROGRAMMING.
