4.1 Exit Menu
Pressing the rotary control on this menu item will cause the ASX-1 to exit the menu system. All
changes made during navigation of menu system will be saved in non-volatile memory on exiting the
menu system.
If you remove power before exiting the menu the instrument will not save any
changes.
4.2 Maximum Values
To avoid false recordings, the maximum values function is only activated 10 seconds after the
instrument has powered up.

menu.
Move the highlight over this menu item and press the rotary button to reset the maximum altitude
and airspeed values to the current values.
4.3 Flight Log
The ASX-1 uses the following algorithm to determine if a flight is in progress (Detect Mode):
If airspeed is greater than the preset flight take off airspeed for the duration of 60 seconds or more,
a flight is started with a logbook entry. The flight ends if airspeed falls below the preset flight take off
airspeed for 30 continuous seconds. During a flight the logbook cannot be viewed.
The above algorithm ensures that touch-and-goes will not result in the end of a flight and a logbook
entry. Should the instrument be switched off during a flight, this will end the flight and the log will reflect the time until the
instrument was switched off. Should the instrument be switched on again during a flight, a new flight will start for logging
purposes.
Move the highlight over this menu item and press the rotary button to return to the main menu.
Note:
(ADC Values and Calibrate Menus are only visible when powering up the unit and pressing the
Rotary Control). The text “CALIBRATE” will appear on the intro screen when entering this mode.
Warning:
The Calibrate Menu is for technical personnel only. Changing any values in this menu may
cause the instrument to display incorrect information, and may require the instrument to be returned to
the factory for recalibration.
