Reset as follows:
Turn off instrument power, then depress CLEAR MENU and WAVE-
FORM, holding in both buttons until you have turned instrument power
on again and the instrument has returned to its normal operating state.
CAUTION.
Loading new software will result in loss of instrument calibration
constants and user presets. Therefore, the program NVSAVE must be run
before executing
UPGRADE
.
CAUTION. If a disk is used to upgrade more than one instrument, finish one
upgrade, including the NVRESTOR program, before running NVSAVE on the
next instrument.
NVSAVE
will overwrite the temporary files on the disk every
time it is run; any previous files will be lost.
CAUTION.
The programs are designed to read or create their respective files in
the current DOS directory. If you choose to copy these files to a hard drive, be
sure to run them from the directory in which they are contained.
