20.4 Fixing the ‘Home’ location
Thehomelocationislockedatrsttakeoffwhenthebatteryisinserted.A long beep upon
takeoffindicateshomelocationlock.Ifthehomelocationcannotbelockedduetono/
weakGPSreception,theNavigator250continuouslysoundsdoublebeepsduringight.
Ifyoustartedthemotorsinanotherthanyourpreferred‘Home’location,turnthemotorsoff
andunplugandreconnecttheightbattery,thenregisteranewhomelocationbyturning
the motors on again.
Intheappyoucanenableawarningsignal(disabledbydefault)incasethereisno‘Home’
locationlockedattake-off.Withthesignalenabled,ifyoutakeoffwithoutlocked‘Home’
location,theNavigator250continuouslyemitsdoublebeeps.
20.5 The importance of the GPS signal
ForR.T.H.towork,agoodGPSsignalisrequiredatalltimes.
■
Itmaytakeupto10min.forGPSsignalacquisitionthersttimeyouturniton.
■
Forsubsequentsignalacquisitionthetimemaybeshorter(1to2min.).
NotethatwheneveryoumovetheNavigator250toanotherlocation,thesignalacquisition
time may increase again (1 to 10 min.). Depending on the GPS signal strength, the
Navigator250behavesdifferently.
Thebelowtablesummarizesallpossiblebehaviours.
