Restoring Settings After Power Interruption
Instantaneous power interruption resets the 4286A to default settings. The 4286A must,
therefore, be set to your own settings again after power interruption. To do this, you can use
the backup SRAM disk memory or built-in
exible disk drive to automatically restore your
settings.
When you wish to use the
exible disk drive, rst save your settings in the le named AUTOREC
on a
exible disk. Then, insert this disk in the disk drive and keep it inserted while the 4286A
is running. When you wish to use the SRAM disk memory, save the AUTOREC le on the disk
memory. In either case, the 4286A will read the contents of this le to recall its settings and
calibration data if the power is interrupted. AutoRecall provides a fast way to recover your
4286A settings after power interruption.
Note
When you have the AUTOREC le stored in both the
exible disk and RAM disk
memory, the contents of the le in the
exible disk will be read into the 4286A.
All data in the disk memory will be lost in 3 days after power interruption.
Backup batteries can be automatically recharged when the 4286A is ON.
