[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-

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

of the antenna would produce a dead sector (ar-
ea 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 ar-
ea, enter 0 for both the [START] and [ANGLE]
sections. The setting range of [START] is 0° to
359° and [ANGLE] is 0° to 180°.
Note: Turn off a stern blind sector before 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
