REDUCING SEA CLUTTER
The sea clutter control is normally used on the shorter ranges to suppress the
effect of sea clutter close to own’s ship.
Press the J-DIAL until the SEA appears highlighted on the upper right corner
of the display. Rotate the J-DIAL clockwise or counterclockwise to vary the sea
clutter control and thus control the strength of echo returns from sea surface
clutter. There is an on-screen bar indication of the sea clutter control level in
use.

ADJUSTNG RAIN CLUTTER
Press the J-DIAL until the RAIN appears highlight on the upper right corner of
the display. Rotate the J-DIAL clockwise or counterclockwise, to vary the rain
clutter control and thus control the strength of echo returns from rain or snow.
As you rotate clockwise, the return echoes will become narrow and the returns
from rain or snow will be reduced. An on-screen bar indicates the selected rain
clutter level.

SETTING CRT BRILLIANCE
Press the BRIL/DIM key, and then rotate the J-DIAL clockwise or counter-
clockwise to change the display brilliance.

SETTING DIMMER
By pressing the BRIL/DIM key, the back light for the panel illumination can be
varied in intensity. Dimmer level is reached at maximum brightness, and the
next level returns the dimmer level to the lowest level (OFF).
OPERATION
On short range scales, the setting of the sea clutter control should
never be advanced so high as to completely obliterate all clutter,
since this setting could prevent the detection of close-in target
echoes.
CAUTION
