A UTO MODE-C ALT
The STX 165 is designed to turn on in the Standby (SBY) Mode. The user can select an altitude at
which the STX 165 will automatically select Mode-C (ALT) Mode. This altitude is the differential
altitude from when the STX 165 was first turned on. To select an Auto On altitude:
1.
Rotate the Data knob to select the AUTO MODE C ALT page.
2.
Press the Enter Pushbutton. The Auto Alt On altitude will be blinking.
3.
Rotate the Data knob to select the desired Auto On Altitude. The altitude will change in
25 foot or 10 meter increments.
4.
Press the Enter Pushbutton
Note: The Auto On Altitude and the EFT Altitude are the differential Altitudes
from when the STX 165 is turned on. For example if the Auto On altitude is
set for 200 feet and the STX 165 is turned on at 1200 feet, the STX 165 will
automatically select ALT Mode at 1400 feet.
EFT START ALT
Note: If 0 (zero) feet or meters is selected in AUTO MODE C ALT, the STX
165 will turn on in the ALT Mode. This is generally not recommended. If
OFF is selected, the pilot will be required to select the ON or ALT Mode.
The STX 165 starts with the EFT displayed in the lower right hand corner of the display.

altitude. It the EFT is set at 0, then the EFT will begin counting at turn on. To set the EFT
start altitude:
