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, 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 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.
To clear the NVRAM:
1. Power off the receiver.
2. Press and hold the Function button.
3. Press and release the Power button for one second.
4. Verify that the Tracking Status LED is solid green.
5. When the Tracking Status LED blinks orange, release the Function button.
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) Online Help
for
more information about connecting the receiver to a computer.
2. In TRU, connect to the receiver.
3. Click the Tools icon in the main window.
The Tools
window appears, enabling you to reset the receiver and clear the NVRAM.
