Sony Airpeak S1 Help Manual page 83

The RTH (Return to Home) function may be affected by weather, the surrounding environment, or nearby magnetic
fields.
The aircraft cannot avoid obstacles if there is not enough surrounding light during RTH (Return to Home).
Set the altitude for obstacle avoidance before performing RTH (Return to Home).
RTH (Return to Home) does not work when there is an insufficient GNSS (Global Navigation Satellite System) signal
(3 or fewer signal bars in the status bar of the "Airpeak Flight" App) or no signal is received from the GNSS (Global
Navigation Satellite System).
About the remaining battery level
If you are notified of low battery, land the aircraft immediately and safely.
When the battery level drops below a certain level, a warning is displayed and the aircraft automatically starts
descending to perform a forced landing. In order to steer the aircraft to an appropriate landing point while maintaining
altitude, operate the remote controller to perform ascent while the aircraft is descending.
If a battery level warning appears on the "Airpeak Flight" App screen, land the aircraft at the Home Point or a landing
point immediately. If the battery packs run out of battery during flight, the aircraft may crash onto the ground,
including private property, causing injury or damage to people or animals.
