SEL knob
This rotary switch is used for VFO frequency tuning, memory
channel selection, and receiver audio volume level adjustment.
SEL/DIAL key and Indicator
The SEL key switches the synthesizer steps of the SEL knob between the fine tuning
(same as DIAL knob step) and coarse tuning (same as SEL knob step) modes.
When the “fine tuning” mode is selected, the SEL LED glows orange.
Press and hold in this key for one second to enable the “VOL” feature, which allows
adjustment of the receiver audio volume level (by adjusting the SEL knob). When the
“VOL” feature is engaged, the SEL LED glows green.
To return to the synthesizer step-selection mode, just press the SEL key.
