Resetting the Receiving (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, elevation masks,
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 performing a factory reset of 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 about 15 minutes to collect new ephemerides and almanacs.
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.
