CHECKING FOR VIBRATION LEVELS
Even with the shock absorbing mount, your aircraft set up may not meet the
vibration damping requirement.
To check for vibration level, please follow this procedure ：

Installing the entire system as recommended (ensure correct
orientation).

With the system fully operational,
carefully run the plane engine or
motor at different throttle levels. DO NOT TAKE OFF.

Increase the motor throttle incrementally & maintain for 20 seconds
at each position. Observe the state of the Red LED light. If it stays
OFF, that means your vibration level is acceptable.

If instead the red LED lights up bright & stays ON solid, then vibration
is too high. You will need reduce the level of vibration on your aircraft.
Add additional damping, change the FY41AP location or balance your
engine / propellers to reduce vibration.
IN-FLIGHT SYMPTOMS OF TOO MUCH VIBRATION

In the stabilized mode, the plane cannot keep a steady attitude. It may
suddenly roll or pitch or show other abnormal attitudes.

Under the stabilized mode, after flying for a while, course direction and
flight attitude changes erratically.

All autonomous navigation modes (assisted by GPS) cannot function
normally.
