75| USER MANUAL
Motors should spin freely, and there should be no grinding or scraping sound from
the motor. The inside of the motor should be free of debris.
Always turn on the radio controller before plugging in ALTA. Follow the battery
installation guidance in the Battery Installation section of this manual for battery
installation instructions.
While the SYNAPSE flight controller initializes, keep the ALTA as stable as possible.
If ALTA moves during initialization, it many not boot properly. Wedging a foam prop
protector between the stationary gimbal or landing gear and the ALTA frame can be
used to stabilize ALTA from spinning during this process.
When it is impossible to initialize ALTA without movement (such as booting on a
boat), Motion Booting can be used. It is not recommended to use Motion Booting
regularly.
During initialization, the Status Light will quickly flash a sequence of red and
white lights. At the end of this process, it will begin slow flashing white, indicating
SYNAPSE is ready for arming. The Orientation Lights will also begin flashing
green. Verify that all six motors are flashing green, indicating all ESCs initialized
successfully.
Verify that there are no flight warnings by connecting to ALTA via the ALTA app and
checking on its status from the App. For more information, see the ALTA App section
of this manual.
