Resetting the Receiver (Clearing the NVRAM)
The receiver’s Non ‐ Volatile Random Access Memory (NVRAM) holds data required for satellite tracking, such as ephemeris data
and receiver position. The NVRAM also keeps the current receiver’s settings, such as active antenna input, elevation masks and
recording interval, and information about the receiver’s internal file system. Clearing the receiver’s NVRAM resets the receiver
and restores the factory default settings.
Although resetting the receiver is not recommended as a common practice, there are times when it can eliminate
communication or tracking problems.
After performing a reset, the receiver requires time to collect new ephemerides and almanacs (around 15 minutes).
Resetting the receiver will not delete any files already recorded in the receiver’s memory, and the NVRAM keeps information
about the receiver file system.
You can also use TRU to clear the NVRAM:
1. Connect the receiver to a computer, and open TRU. See the Topcon Receiver Utility ( TRU) Reference Manual for
more information about connecting the receiver to a computer.
2. In TRU, connect to the receiver.
