Hello,
It is not possible to 'reset to factory defaults' as the parameters are managed in the checkmate application. In order to changing logging parameters in a GO device, a parameter key must be created in checkmate and then inserted into the GO device.
Please provide more information about the issue you are experiencing.
If you require phone support, please visit the
contacts page on www.geotab.com and submit your contact details. Please include the company which the system was purchased from so that we can include your dealer in the troubleshooting process.
