Solution
Run Self Test
Run Self Test up to three (3) times and then
contact Teledyne GMI Customer Service
Replace or recharge battery pack
Move closer to the target
Change angle to target to get a better reflecting
background
Check battery level and recharge if necessary
- Slow down the scanning rate
- Pause at the long range and sweep towards you
Increase the Alarm detection threshold
Move in closer
Avoid making abrupt motions while scanning
Increase the Alarm Detection Threshold
Perform Self Test procedure
Check the Alarm Detection Threshold
Check battery level and recharge if necessary
Allow for the instrument temperature to stabilize
Note error message and contact Teledyne GMI
Charge battery pack until solid green light on
charger is on
Replace battery pack, and properly dispose of
exhausted battery pack
Change angle to the target for a better background
Move in closer
Change angle to the target for a better background
Verify credentials
Place unit closer to WiFi point
Enable WiFi in menu
Enable Bluetooth in menu
Pair device with instrument
Use another USB cable
Try another USB port or allow computer to load drivers
Charge or replace battery pack
