External bus error!  
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. 
  Flight Battery Not Detected 
  The low battery autoland feature has detected that no battery is 
connected. 
  Flip crash detected! Disarmed 
If the Vector detects that the multirotor has flipped over after a crash, it 
will disarm the motors to try to avoid burning them out. 
  Flyaway detected-Disarming! 
The Vector has detected an uncontrollable flyaway condition due to 
miswiring or bad configuration, and is disarming the motors to avoid 
loss of the multirotor.  
  Freefall detected!!! 
This is an informational message that will display if the Vector detects a 
freefall. This would normally only occur if total loss of motor power or 
thrust has occurred, or if the multirotor has been disarmed during flight. 
Gain Knob used but undetected 
This message will appear if you configured the gain knob, but the 
Vector’s gain receiver input is not detecting a signal during boot. 
GPS Status: Awaiting first fix 
Indicates that the Vector is waiting for the GPS to acquire a fix. 
GPS Status: Awaiting 3D fix 
Indicates that the Vector is waiting for the GPS to acquire a 3D fix. See 
GPS Configuration menu. 
GPS Status: Awaiting Enough Sats 
Indicates that the Vector is waiting for the GPS to acquire enough 
satellites. See GPS Configuration menu. 
GPS Status: Awaiting HDOP 
Accuracy 
Indicates that the Vector is waiting for the GPS to have a low enough 
HDOP (Horizontal Dilution of Precision). See GPS Configuration menu. 
GPS Status: Post-Fix Countdown 
Indicates that the Vector is waiting for the amount of time specified after 
the GPS fix is finalized, in the GPS Configuration menu. 
GPS Not Connected! 
The Vector has detected that the GPS is not connected. Check cabling. 
GPS Fix Lost! 
This indicates that the GPS has lost its position fix. All GPS modes, 
including RTH, will be disabled until it regains a fix. 
GPS/Compass has old Firmware! 
This message indicates that the firmware on the GPS/MAG needs to be 
updated. GPS/Mag firmware updates automatically occur when you 
update the Vector firmware, as long as you have the GPS/MAG 
connected to the Vector at the same time. 
Gyro not detected!  
If you repeatedly see this message, DON’T FLY and contact support. 
Home Waypoint too far away! 
You set up a Home Waypoint in the software, but that waypoint is more 
than about 500 feet (152 meters) from the GPS’s first fix location. 
  Idle throttle being reduced! 
The Vector has detected that you are commanding the multirotor to 
descend by throttling down, but the multirotor is not descending, 
possibly due to too high of an idle throttle setting. Please land and 
reduce your idle throttle. 
  Impact Detected! 
This message tells you what you probably already knew. :( 
  Kill Switch Activated!! 
This message appears when you activate the motor kill switch. 
Landing - Poor GPS or Mag 
This message indicates that the model is landing (normally during RTH) 
if the GPS signal or compass calibration is too poor to continue returning 
home. 
  Lipo cell count incorrect? 
This message is displayed at boot when low battery autoland is enabled, 
and you have connected either an almost dead battery, or a battery that 
is overcharged. If you have manually defined the number of cells in your 
battery for the autoland function, this message will also be displayed if 
the detected cell count does not match the stated number. 
Logging Buffer is Full 
This message will appear when the data logging buffer is full, if you have 
disabled automatic clearing of the logging buffer.
