Factory reset for GR-i3 with TRU

Use the Topcon Receiver Utility (TRU) to reset the GNSS receiver parameters to the default values and erase the Non-Volatile Random Access Memory (NVRAM). NVRAM holds necessary data for satellite tracking. A factory reset does not delete any files from the receiver and does not reset modem parameters.

Complete a factory reset after you save a new GNSS firmware file, or to correct communication or tracking problems.
ADDITIONAL INFORMATION:
It is necessary to give the receiver up to 15 minutes to collect new ephemerides and almanacs after a factory reset.
