Operation and Usage Explanation
Press the button and hold on for 1~2 second, a power on alarm is triggered which will sounds like ‘1-2-3’ with a flashing white led.
If there is no VCC5V0 detected for a certain period of time (about 30 seconds) after the power is turned on, a missing alarm will automatically sound(B-B-B). This situation occurs when a drone is crashed and the main battery supply is lost (so the VCC5V0 output of the FC lost at the same time).
If continuous VCC5V0 is present and detected after a drone crash, then we could triggered the alarm by transmitter Aux channel switch that pre-configured to BEEPER feature.
After use, to turn off the power, press the button and hold on for 1~2 second, then a power off alarm is triggered which sound like ‘3-2-1’
