20.2 Manual trigger
■
Deactivated: R.T.H switch (switch ‘SWD’) in position 1
■
Activated: R.T.H switch (switch ‘SWD’) in position 2
20.3 Procedure
When triggered, returning to home follows a simple two-step procedure: the Navigator 250
is automatically brought into a stable hover position, then returns home. Study »Fig. 13.

20.4 Fixing the ‘Home’ location
The home location is locked at first 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 flight.
If you started the motors in another than your preferred ‘Home’ location, turn the motors off
and unplug and reconnect the flight 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 first 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.
GPS signal Switch position
Good signal at take-off and when
R.T.H. is triggered
Navigator 250 returns home.
Weak signal at take-off, but
improved signal during flight
Navigator 250 holds its position for 5 seconds,
then descends and lands.
Signal weakens during flight Navigator 250 descends immediately.
