A: Click "Search Bluetooth Devices" again; ensure that the location information on the device is on; check if the device is powered on; confirm if the Bluetooth name of the device has been changed; ensure that the device is not too far away from the device.

A: Re-search for Bluetooth and then connect with it again; Pairing is necessary for initial connection.

A: Check if the surroundings meet the satellite reception conditions; check if the registration code has expired; verify if there is any regional restriction; ensure that the Bluetooth is connected; confirm if the satellite system is turned off.

A: Go to "Configuration" -> "Instrument Registration" -> Input the registration code -> Click "Register."

A: Select "Projects" -> "About Software" -> "Software Activation" -> Enter the registration code -> Click "Activate."

A: Check if the controller has internet access; verify if the CORS IP address, port, username, and password is correct.

A: Check whether the device is inserted with SIM card; check if the mobile network is online; verify the correctness of the CORS IP address, port, name, and password.

A: Verify if the controller connected to the Internet; ensure the CORS account is valid; ensure the satellite reception environment is good; check if there is any thunderstorm.

A: Check if the SIM card is inserted into the device; ensure if the device has internet access; ensure the CORS account is valid; ensure the satellite reception environment is normal; check if there is any thunderstorm.

A: Check if the built-in antenna is connected; configure the radio protocol and frequency to match the base station; ensure the satellite reception environment is good; check if there is any thunderstorm or bad weather.

A: Check the PDOP limit and height cutoff angle; check if the satellite reception environment is good; check if there is any thunderstorm or bad weather.

A:Check if the fixed coordinates are used to start the base station, and if the deviation between fixed coordinates and actual coordinates is too large; it is suggested to re-obtain fixed coordinates or switch to single-point coordinates to start the base station.

A:The tilt is on, but the inertial navigation correlation is ignored or done improperly.

A:Ensure that the input pole height is consistent with the actual pole height; rock the centering pole back and forth for 5-10 seconds. If convergence is not completed, just rotate the centering pole 90 degrees, then rock the centering pole back and forth for 5-10 seconds.

A:There is a positioning icon behind the central meridian of the coordinate system. When the device is connected and the stars are collected, clicking on it can automatically obtain the correct central meridian.

A: Go to "Configuration" -> "Instrument Settings" -> "VPN Settings" -> Click "Default" -> Click "Confirm."

A: Check if the device is inserted with a SIM card; check if the device has internet access.

A: Go to "Project" - > "Data export" - > Select data format and length unit for export - > Click "Export".

A: Go to "Project"->"Data Import"->Select data format and parameters for import->Click "Next"-> select the file to be imported - >Click "OK".
