3.5.3 [SCANNER] menu
Open the main menu then select [RADAR INSTALLA-
TION] [SCANNER] to open the [SCANNER] menu.
[SECTOR BLANK1(2)]
Set area(s) where to prevent transmission. Heading
must be properly aligned (see section 3.2) before set-
ting any blind sector. For example, set the area where
an interfering object at the rear of the antenna would
produce a dead sector (area where no echoes appear)
on the display. To enter an area, enter start bearing rel-
ative to the heading and dead sector angle. To erase
the area, enter 0 for both the [START] and [ANGLE]
sections. The setting range of [START] is 0° to 359°
(default: 000°) and [ANGLE] is 0° to 180° (default:
000°).
Note: Turn off a stern blind sector when adjusting the
PM gain, to display the echo from the performance monitor properly.
