3.5 Turning the LX 10k off
The LX 10k can be turned off in different ways, depending on the configuration you have.
All units will start the shutdown process once the power supply is cut from the main power
lines, unless in flight mode.
There is a possibility of a manual shutdown by going to Setup > Shutdown and confirming by
choosing ’Yes’.
In case a device requires a force shutdown, there is a possibility of performing a hard
shutdown by pressing and holding the ZOOM push-rotary knob for 10 seconds.
3.6 Turning the indicator ON and OFF
In all cases of normal operation, the LX 10k vario indicator (be it analog or digital) requires no
special handling in order to turn on or off.
The indicator will turn on automatically once the main unit has been turned on, and will shut
down once the main unit has been shut down.
If one wishes to perform a hard shut down of the vario indicator, it can be done by pressing
and holding for 10 seconds the push rotary knob on the vario indicator.
3.7 A word on internal battery and flight mode
All LX 10k devices (including the vario indicator) have a built-in reserve battery, intended for
supplying the unit with power in case your aircraft losses its main power supply. The reserve
battery is not intended for use on the ground, which is why the device can not be turned on, on
reserve battery alone.
Flight mode is a term describing a state in which the LX 10k is, when the device detects it is
flying. For getting into flight mode, one of the following parameters must be met:
• GPS lock is present, and
• GPS speed is above 10 m/s, or
• airspeed larger than 10 m/s is present, or
• significant movement in vertical speed
Once in flight mode, the LX 10k will not turn off if the main power supply is cut, but continue
operating as long as there is internal power, or until the main power supply is reestablished.
The internal battery powers all of the internal features of the LX 10k, which covers everything
described in this manual. The LX 10k will continue logging, with IGC seal intact, it will continue
providing you vario information, sound warnings, complete navigation, etc.
