a) The BW +/- key changes the demodulation bandwidth and the dark blue
region displays the bandwidth in relation to the IF span.
b) The AFC
key toggles automatic frequency control. When a peak is within the
demodulation bandwidth (3), AFC helps to track and keep the demodulation
frequency tuned to the frequency of the peak. AFC does not function in SSB
(USB or LSB) demodulation mode (4d).
c) The DET key changes the level detection mode (Average, Peak, Fast, RMS)
of the RF amplitude envelope.
d) The DEMOD +/- key changes the demodulation mode (CW, LSB, USB, ISB,
AM, FM, Pulse, PM, IQ). CW, USB and LSB demodulation modes are only
available with demodulation bandwidths (4a) of 9 kHz or narrower.

The SELECT Rollkey & Control (chapter 2.1, "Front-Panel Tour", on page 13)
allows changes to various receiver functions.
