Anritsu 681XXC - Manual (Page 123)

Erasing
Stored Setups The front panel setups are stored in non-volatile
memory. A master reset is required to erase the con-
tents of the setups and reprogram them with default
data.
To perform a master reset, proceed as follows:
Step 1 With the 681XXC in standby, press and
hold the RF OUTPUT ON/OFF key.
Step 2 Press the LINE OPERATE/STANDBY
key to turn the instrument on.
Step 3 When the first menu is displayed (after
the start-up display), release the RF
OUTPUT ON/OFF key.
The contents of non-volatile memory have now been
erased and reprogrammed with default data.

NOTE
The master reset function over-
writes all information stored in the
non-volatile memory with default
values. This includes the table of
2000 frequency/power level sets
used for the list sweep mode and
the five power-offset tables used for
the user level flatness correction
function.
