9.4. Clearing the NVRAM

The receiver's Non-Volatile Random Access Memory (NVRAM) holds data required for satellite
tracking, such as almanac and 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.
Even though clearing the NVRAM is not a common (nor normally a recommended) operation, there are
times when clearing the NVRAM can eliminate communication or tracking problems. Clearing the
NVRAM in your DELTA can be interpreted as a "soft boot" in your computer. After clearing the
NVRAM, your receiver will require some time to collect new ephemerides and almanacs (around 15
minutes). Clearing the NVRAM of your receiver will not delete any files already recorded in your
DELTA's memory. However, it will reset your receiver settings to factory default values.
In addition, the NVRAM keeps information about the receiver file system. Note that after clearing the
NVRAM, the receiver's SAT LED will flash yellow for a few seconds indicating that the receiver is
scanning and checking the file system.
