[PM GAIN ADJ]
Adjust the performance monitor,
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.
Note: This menu is NOT avail-
able when the [RADAR] setting is
set to [SUB] for FAR-2x58 (see
"[RADAR]" on page 3-14).
1. Adjust the GAIN control so that a slight amount of white noise appears on the
screen. Arcs for the performance monitor appear on the screen.
2. Select [PM GAIN ADJ] then spin the scrollwheel so that the outer arc faintly ap-
pears. The setting range is 0 to 255 (default: 255). Wait at least eight scans then
right click to set.
Note: Turn off a stern blind sector before adjusting the PM gain, to display the
echo from the performance monitor properly.

Select [YES] to reset all PM graphs, after replacing the magnetron.
Note: This menu is NOT available when the [RADAR] setting is set to [SUB] for FAR-
