RM (Relative Motion): The ship will stay in the center of the screen
or at an offset position and targets will appear relative to own ship’s
position.
 If receiving the alarm: “Heading missing” or “Position missing” the
system will change to Head-Up in Relative Motion after 60 seconds
and at the same time inform of “Changing to HeadUp” in a pop-up
window.
0.50nm indicates the displayed range in the radar picture.
Power off indicates that the radar function is not active.
TI is the Tuning Indicator, which provides an indication of the
receiver tuning.
Tune – make manual adjustments to Tune by means of the +/- keys,
and return to AUTO mode by pressing [CLR].
Tune control – is a variable control used to tune the receiver in the
radar antenna for maximum target returns on the display. If no land
or ship targets are available, the operator may tune for maximum sea
clutter. The tuning indicator will show the strength of tuning peak
conditions and is tuned for maximum deflection. Tuning of the radar
should be performed on a 3nm range scale or higher.
Gain – Auto mode can be used in most situations, but in some situa-
tions manual adjustment leads to better performance of the system.
Make manual adjustments to Gain by means of the +/- keys, and
return to AUTO mode by pressing [CLR].
Gain control adjusts the gain level of the radar’s receiver. The Gain
control level is usually set for the best target presentation with a slight
noise speckle in the background on the 12 or 24nm range. A semi-
automatic Gain reduction is used on shorter ranges to improve target
definition. Use some caution when adjusting the Gain control. If gain
is set too low, small or weak targets may be missed. If the gain is set
too high on short ranges, the display may become excessively covered
with noise speckle making target observation difficult.
Sea – Auto mode is optimized for open sea and is recommended when
the distance to shore is over 300 meters. Closer to shore and when
approaching a harbor, choose Harbor mode.
Make manual adjustments to Sea by means of the +/- keys, and
