Issue　

Smart Construction Retrofit error message "GNSS FIX NOT VALID" is displayed.

Cause

• The reception of GNSS signal is weak.
   
• 3DMG construction is not possible.
   
• There may be places and times when captured satellites are not sufficient.

How to deal

• Wait for the satellite placement to improve, or move to another location to see the changes.
• Please restart the engine and the tablet. If it does not improve after waiting for a while, please do the followings.
• Please change the satellite type used. (Example: Select or cancel BeiDou or QZSS)
• Menu > GNSS Settings > GNSS Basic Settings Please tap the Soft Reset button.
• It is also possible that the amount of correction data is not appropriate. It can not fix if the amount of correction data is too much or too little. In the case of using base station, try changing the amount of correction information to be delivered. In the case of using Ntrip, switching the mount point may solve the problem.
• Interference with the wireless channel used by the dump truck etc. is also possible. In some cases, it can be resolved by changing the channel.
• If the controller firmware or tablet application version is not the latest, please update it.
• The calibration file may have been initialized, so overwrite it with the backup calibration file.
• The antenna position may be different from the one at the time of calibration. Please recalibrate.
