ECHO ADJ menu

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 and push the thumbwheel. With

the gain set to 80, spin the thumbwheel until noise just appears on the screen. Default setting is

30 for the antenna cable length of 15 m. The setting range is 0 to 73.

To adjust the cable attenuation automatically, choose AUTO and push the thumbwheel. The

message "CABLE ATT ADJ" appears (in red) at the bottom of the screen. It takes about five min-

utes 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 from 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

The default setting is suitable for most conditions. If necessary, change the setting according to

sea conditions.

RING SUPPRESSION

This is mainly used to removes "ring" noise that 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.
