If the following conditions occur, the DOS initialization is recommended:
(1) The device has not been used for a long time.
(2) There is a change in environmental temperature of over 30 degrees since last flight.
(3) The purple LED flashes continuously even when the DOS remains stationary and you never activate the
motor.

not necessary and not recommended.
● The stabilizer unit does not need to be in a horizontal position during initialization. However, you must
ensure there is no vibration during this process. If suspect shaking occurred during the procedure, just restart
