Erasing the Power-Offset Tables from Memory
The power-offset tables are stored in non-volatile
memory. A master reset is required to erase the con-
tents of the tables and reprogram them with default
data.
To perform a master reset, proceed as follows:
Step 1
With the 681XXB 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 OUT-
PUT ON/OFF
key.
The contents of non-volatile memory have now been
erased and reprogrammed with default data.
