1. Deactivateddevice
Thedisplayisemptyandwhenevertheleftorrightbuttonispressed,intentionally orby
accident, thedisplayindicates [ OFF ] .
2. Device activation
Thedevice isstarted bypressingthebuttonsoftheso-called activationsequence several
times.Firstreleasebothbuttons.Press theleftbuttonandkeep itpressed (o).Afterthree
seconds,thedisplaywill shownumberone [1].Press therightbutton (>) three timesin
arowandreleaseit.Aftereachpressingthedisplaywill showagrowingrowofnumbers
[ 12 ], [123 ] and [1234 ].Once numeral4hasappeared onthedisplay,releasetheleft
controlbutton (o). Thisactivationsequence isthencomplete.Thewholesequence must
not lastlongerthantenseconds.Ifamistake ismade thewholeproceduremustbe
repeated.
Thedisplayshows [ON ] briefly andthenitimagestheremainingcapacityofthebattery
rangingfrom [100%] to [0%].Subsequently,automaticcalibrationtakesplace and

3. Machine deactivation
Turnoff thedevice inthesamewayinwhichyouactivated it–i.e.bymeansofthe
activationsequence.Thedisplayshows [ OFF ]. Ifyouforgetto turnthedevice off, itturns
off automatically once thetimeofthestand-bymode hasbeenfulfilled.Thedevice canbe
turned off duringthestand-byandjumpmodes.
4. Calibration
Calibrationiscarried outto setazeroheightforthelandingsurface.Itisstarted when
activatingthedevice andthenautomatically aftereachjump.When [CAL] appearsonthe
display, thedevice measuresacurrentpressureandsetsitasaheightzerovalue.
Therefore,youshouldalwaysactivatethedevice only inthearea ofthelandingsurface.If
