Remarks
With the *SAV command, you can use location 0 to store a fifth instrument
state. However, keep in mind that location 0 is automatically overwritten
with the power-down state when power is cycled.
When shipped from the factory, storage locations 1 through 4 are empty
and the instrument is configured to automatically recall the power-down
state (location 0) when power is restored. You can change the factory
configuration such that a Factory Reset (*RST command) is issued when
power is restored.
A Factory Reset (*RST command) does not affect the value of <mode>.
