ECHO ADJ menu
[VIDEO LEVEL ADJ]
: Adjust the cable attenu-
ation manually. Set the radar as follows:
Interference Rejector (IR)
: 2
Echo Stretch (ES)
: OFF
Echo Averaging (EAV)
: OFF
Gain
: 80
Range
: 24 NM
Pulse Length
: Long
Select [+] or [-]. Rotate the scrollwheel so that
noise just disappears from the screen. The set-
ting range is 0 to 32. After completion of the ad-
justment the radar goes into standby. If the
noise does not disappear, switch to [-]([+]) and
try again.
[STC CURVE]
: Use the default setting. Change
the setting according to sea condition. The larg-
er the number the greater the STC effect.
[RING SUPPRESSION]
: Remove “ring” noise
which appears with the waveguide-type radar.
Adjust so the rings disappear at the range of 0.125 nm. The setting range is 0 to 255.
SCANNER menu
[BLIND SECTOR 1], [BLIND SECTOR 2]
: Set
area(s) where to prevent transmission. Heading
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 area, enter start bearing relative to
the heading and dead sector angle. To erase
the area, enter 0 for both the [START] and [AN-
GLE] sections. The setting range of [START] is
0° to 359° and [ANGLE] is 0° to 180°.
Note
: Turn off a stern blind sector when adjust-
ing the PM gain, to display the echo from the
performance monitor properly.
[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 selected.
Note
: Select [OFF] at [ANT SW] to prevent antenna rotation. [ANT STOPPED] pre-
vents transmission while the antenna is stopped in STBY.
