2.3.11.1 NVRAM Description
The 2400 Series uses non-volatile memory “NVRAM”, preserved with a battery for storing the Instru-
ment’s current state, saved Setups and Lists. The NVRAM is “checksummed” meaning at boot-up, the
firmware checks if any value has been changed.
2.3.11.2 Clearing NVRAM & System Memory
Using the front panel power switch, turn the 2400’s power off.
Power up the 2400.
Press and hold the “PRESET” button until the initializing NVRAM window appears. Release the “PRE-
SET” button.
The system will continue to boot normally. All information stored in the memory locations will be
cleared. The system will set up to factory default settings.
