LX 10k
Taking care of your LX 10k
Document name: LX 10KUM
Document revision: R1
WARNING
Draining the battery completely will cause the LX 10k to lose its IGC seal. If this
happens, the pilot will be prompted by a red warnings stating ’Seal not valid!’,
when powering up the device. All flights recorded without a valid seal will not be
IGC valid, meaning they can not be used for badge flights, record flights,
competition flights and webpages like OLC will not calculate them into your
cumulative score. If this happens, contact LX support as soon as possible.
9.2 Pressure sensors
The LX 10k incorporates a variety of delicate pressure sensors. Since these are zero-flux
sensors (there is no airflow through the sensors, only pressure differences), no air filters are
required.
Static pressure sensors have an operating range of 0 to 1200 mbar, with a high resolution of
20cm of altitude. Any overpressure could damage the static pressure sensor permanently,
which is why great caution should be exercised when setting up and testing the pitot-static
system. If the total pressure were to be connected to the static port, and a pilot was to check
the IAS reading by blowing into the pitot tube, damage could easily occur.
The differential pressure sensor has an operating speed of up to 325 km/h (50hPa). Flying
over this speed, or applying the equivalent pressure, may damage the sensor permanently.
9.3 Display
Leaving the glider canopy open in the sun is known to have a magnifying glass effect, concen-
trating the sun rays to a smaller area. This can damage the internals of your cockpit, as well
as the display of the LX 10k. Applying excessive heat will make the coating of the display start
to become yellow and bubble (best case scenario), or destroy the device completely.
This is why it is prudent to always have your canopy, or your instrument panel, covered from
direct sunlight.
9.4 Device housing
By FAI IGC rules, visible external damages to the housing of the LX 10k can void your com-
petition, record or badge flight, from being processed as valid. Care should be taken not to
damage the housing and the ’Data not valid if seal is broken’ stickers not to be torn up.
9.5 RJ connectors
RJ connectors (RJ12 and RJ45) on the back of the LX 10k are used for connecting external
devices. If the cable is pulled out, without pressing the plastic security pin, the internals of the
