The current setup is saved, the operating system shuts down and sets the instru-
ment to standby state.
The [On/Standby] LED must be orange.

AREG100A (posi-
tion "0" (off)).
The instrument is no longer supplied with AC power.

You can leave the AC power on permanently. Switching off is required only if the instru-
ment must be disconnected from all power supplies.
