automatically or manually, when-
ever the magnetron is replaced.
For automatic adjustment, no fur-
ther operation is required; close
the menu at the completion of the
adjustment. For manual do as
follows to adjust the performance
monitor gain.
1. Adjust the GAIN control so
that a slight amount of white
noise appears on the screen.
