2.5.3 ROTAR Y KNOBS
The rotary knobs provide control of the Selected Altitude. The outer knob changes Selected
Altitude by 1000 foot steps. The inner knob changes Selected Altitude by 100 foot steps.
If remote baro--correction is not selected, the rotary knobs can also be used to enter
baro--correction. For 3.0 seconds after pressing the BARO pushbutton and for an additional 3.0
seconds following any subsequent rotary knob movement, the numeric display will show the
present baro correction and the rotary knobs will adjust the baro--setting instead of Selected
Altitude. In this mode, the outer knob will change the baro--setting by 0.1 in Hg or 10 hPa. The
inner knob will change the baro--setting by .01 in Hg or 1 hPa.
