CABLE ATT ADJ
Before adjusting, set the radar as follows:
IR: 2, ES: off, EAV: off, 24nm range, long pulse
(Same as default setting of PICTURE1)
To adjust the cable attenuation manually, choose MANUAL by pressing [2] and the [ENTER]
key, and then rotate the wheel so that noise just appears on the screen when the gain is set
to 80. Default setting is 30 for the antenna cable length of 15m. The setting range is 0 to 73.
To adjust automatically, choose AUTO and press the [ENTER] key. The message “CABLE
ATT ADJ” appears in red at the bottom of the screen. It takes about five minutes to
complete the adjustment, after which the radar goes into stand-by.
DEFAULT ANT HEIGHT
Select height (m) of the radar antenna unit from the sea surface among 5, 7.5, 10, 15, 20,
25, 30, 35, 40, 45 and “more 50 m”.
NEAR STC CURVE, MID STC CURVE AND FAR STC CURVE
Use the default setting. Change the setting if desired according to sea condition.
RING SUPPRESSION
This is mainly used to removes “ring” noise which appears in the waveguide-type radar.
Adjust so the rings disappear at the range of 0.125 nm. The setting range is 0 to 255.
