its present location. This condition could be caused by bad compass 
calibration, a loose or rotated compass, high wind, or a configuration 
problem. Note: You must disarm and rearm the multirotor before RTH 
will function again, once this message appears. The MicroVector 
rebooted due to low voltage from the MicroVector’s power source. This 
could be caused by overheating, a loose connection, or low battery. 
  RTH Engaged: Move sticks to 
cancel 
RTH has been triggered by the mode/submode switches, either 
intentionally, or due to the receiver commanding this switch 
combination during failsafe. 
RTH Engaged: Too Many Rx 
Glitches 
RTH has been triggered because the receiver is no longer sending 
signals to one or more channels. 
RTH Engaged: Bad Rx Pulsewidths 
RTH has been triggered because the receiver is sending invalid pulses 
(too short or too long) to one or more channels. 
RTH Engaged: Rx Failsafe Detected 
RTH has been triggered because the MicroVector has detected that the 
receiver is in failsafe. 
Rudder Issue: Rerun Wizard! 
When you ran the Receiver Analysis Wizard, the MicroVector did not 
detect correct movement of the rudder input. Check your wiring and 
settings and run the wizard again. 
S.BUS Error Detected! 
The MicroVector detected a communication problem with the S.BUS
TM
link. This could be caused by a loose connection, a power problem, or an 
issue with your receiver. 
Submode Input not Detected! 
You configured a submode switch, but the MicroVector did not detect a 
signal at the submode input during boot. 
Throttle Failsafe Incorrect! 
You have selected “Throttle Failsafe” method of receiver failsafe 
detection, but the MicroVector detected that your receiver’s throttle 
failsafe position is either too close to, or higher than, your normal 
throttle off position. Please read section 6.13.1 - ‘Selecting the Failsafe 
Detection Method’ for more info on throttle failsafe detection. 
Throttle Issue: Rerun Wizard! 
When you ran the Receiver Analysis Wizard, the MicroVector did not 
detect correct movement of the throttle input. Check your wiring and 
settings and run the wizard again. 
Too much movement - aborting! 
You invoked the “Record Flat Level Mounting” or “Rezero Gyros” 
command, and the MicroVector detected that the model was moved 
during the operation. 
USB Mode - Outputs Disabled 
The MicroVector’s outputs are disabled whenever the USB cable is 
connected, and they remain disabled until AFTER you disconnect the 
USB cable AND reboot the MicroVector. 
Warning: Too much vibration 
The MicroVector has detected that the vibration levels are too high, 
which can cause control issues.
