Calibration error- see manual 
This message is displayed if an error has occurred with the optional 
altimeter calibration step. 
  Can't arm when RTH triggered! 
If you try to arm when the MicroVector is in RTH mode (normally 
because the mode/submode switches are set to “RTH Test”), this 
message will appear. 
  Can't change when knob used! 
  The controller gains cannot be changed in the menus when the gain 
knob is enabled for that gain. 
Can't do that while flying! 
You’ve attempted a menu operation that cannot be done while flying (or 
armed). 
  If the altimeter or speed sensor(s) are drifting considerably, the 
MicroVector may think that your fixed wing model is flying, when it 
is not. Resetting home or rebooting the MicroVector should remedy 
the issue. 
Channel not detected! 
This message will be displayed when you are running the Serial Rx 
Learn wizard and the requested channel was not detected. This is ok if 
the requested channel is not needed with your setup. 
Compass Needs Recalibraton! 
This indicates that the MicroVector has detected issues with the 
compass calibration. Please recalibrate the compass. This can also 
happen if the compass is rotated, not mounted firmly or level with the 
MicroVector, or is temporarily near large metal objects. 
Compass not Calibrated! 
You have enabled the compass, but have not yet run the compass 
calibration. 
Too much pitch- keep it level 
Too much roll- keep it level 
If these messages appear during the horizontal rotation phase of 
compass calibration, either you are pitching/rolling the model during 
calibration, or you may need to rezero gyros and/or record flat level 
mounting before calibration. 
Cal error 1- retry/see manual

Cal error 3- retry/see manual 
Cal error 4- retry/see manual 
Cal error 5- retry/see manual 
During compass calibration, these message may indicate one or more of 
the following issues: 
* There are sources of magnetic interference near the compass 
(magnets, large metal objects, servos, etc.). 
* There is a strong magnetic field anomaly near your location, such as 
rocks or buildings with high magnetic fields. Try calibrating away from 
such objects. 
* A poor tumble or rotation technique is being used.    
* You may need to rezero gyros and/or record flat level before 
calibration. 
* The MicroVector and GPS/MAG are not mounted with the same 
orientation (level to each other), or the GPS/MAG is mounted loosely. 
Control stick not centered! 
Your control stick must be centered to arm the multirotor. If your 
control stick is centered, please rerun the Receiver Analysis Wizard 
again. 
Elevator Issue: Rerun Wizard!  
When you ran the Receiver Analysis Wizard, the MicroVector did not 
detect correct movement of the elevator input. Check your wiring and 
settings and run the wizard again. 
Emergency reboot occurred! 
If you see this message, DON’T FLY and contact support. 
Error: External sensor issue! 
This message indicates there was an issue communicating with either 
the GPS/MAG, or the pitot speed sensor. If this happens repeatedly, a 
cable is loose or damaged, or there’s a power or sensor problem. 
  Error: Internal sensor issue! 
If you repeatedly see this message, DON’T FLY and contact support.
