3.6.2 [SCANNER] menu
Open the main menu then select [9 RADAR IN-
STALLATION] [2 SCANNER] to open the
[SCANNER] menu.
[1 BLIND SECTOR1], [2 BLIND SECTOR2]
Set area(s) where to prevent transmission. Head-
ing must be properly aligned (see section 3.2) be-
fore setting 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 ar-
ea, enter start bearing relative to the heading and
dead sector angle. To erase the area, enter 0 for
both the [START] and [ANGLE] sections. The set-
ting range of [START] is 0° to 359° and [ANGLE] is
0° to 180°.
Note: Turn off a stern blind sector when adjusting
the PM gain, to display the echo from the perfor-
mance monitor properly.
[3 ANT REVOLUTION]
For HSC only. Select [LO] for 36 rpm, [HI] for 42 rpm. [AUTO] sets the normal rotation
speed to 36 rpm and switches the rotation speed to 42 rpm when the short pulse is

Note: Select [OFF] at [ANT SW] to prevent antenna rotation. [ANT STOPPED] pre-
vents transmission while the antenna is stopped in STBY.
