Flight Control System

1. Before take-off, please observe the surrounding environment and place the aircraft in an open and unobstructed environment to search for satellites. If the number of searched satellites is more than 28, this is good and within the recommended range. If the number of searched satellites is 0 or insufficient, the app will prompt “GNSS signal is weak, and geo-awareness may be disabled.”, please wait until the GNSS signal is normal and try again.
2. If the app prompts “Compass abnormal”, please stay away from interference areas and recalibrate.
3. If the app prompts “IMU is abnormal” please perform an IMNU calibration. If the problem cannot be solved, please contact Autel After-Sales service.
4. If the app prompts “Barometer abnormal”, please restart the aircraft and try again. If the abnormality continues, please contact Autel After-Sales service.

Battery Life

To prolong battery life, please avoid the following situations:

1. Avoid placing the battery in an environment with a temperature above 28℃ for a long time. The ideal storage temperature is 22-28℃.
   2. Avoid storing fully-charged batteries for a long time. In order to protect the battery, BMS has a self-discharge function, lasting for 2-3 days. It is recommended to charge the battery to 60~75% before storage instead of activating the self-discharge function.
   3. Avoid low battery storage. If the power is too low, BMS will enter ultra- low power protection. The battery itself has self-discharge, and if the battery is too low, it will damage the battery. If the aircraft and batteries are stored for long time, please perform a standard charge operation every 3 months.
   4. Avoid placing the battery in a high-humidity and high-salt environment for a long time, which may damage the interface and shell.
   5. Do not use unauthorized chargers. The voltage and current output by unauthorized chargers cannot fully match the battery cells, which may cause damage to the batteries.
   6. Avoid leaving the charger plugged in for a long time as this may damage the charger.
   7. If the battery is left idle for a long time, please charge it every three months to avoid a shortened battery lifespan resulting from long-term low battery levels.
