If the battery cell voltage drops below the Land Voltage, the boom LEDs will flash. The pilot
will remain in full control of the ALTA X in all three flight modes and full throttle authority is
available to the pilot in a battery exhaustion event

Loss of Signal (LOS) can occur if the radio controller stops transmitting a signal, or if ALTA
X is too far away to receive it. In the event ALTA X detects a LOS, it will automatically
execute a Return-to-Land or Autoland as configured in ALTA X QGroundControl if using an
S.Bus/S.Bus2 or DSM2/DSMX radio type. While ALTA X includes these emergency control
modes, it is always recommended to attempt to regain signal link with ALTA X to keep the
pilot in control of the aircraft.
Move the antenna orientation for best signal strength. Ensure the radio antenna matches
the direction of the receiver antennas. Move the radio away from objects to get a clear line-
of-sight to ALTA X.
Set the Mode switch to Position and the Home switch to Return-to-Land so ALTA X will
continue to approach the home point if the signal is momentarily regained, resulting in
higher likelihood of regaining full signal reception.
If efforts to regain control signal are unsuccessful, ALTA X will begin either the Return-to-
Land and Autoland sequence as configured in ALTA X QGroundControl. Refer to the Flight
Controller Modes section of this manual for additional information regarding functionality
available with specific radio types.
