AUTO mode for TUNE.
The TUNE control is used to tune the Receiver
Frequency to match that of the Transmitter.
The tune adjustment should be made on the
medium or long range scales that show radar returns.
The GAIN control adjusts the sensitivity of the radar dis-
play.
AUTO mode for SEA, RAIN and FTC.
The SEA control i s used to suppress radar returns which
are the result of radar signals reflected from waves.
The RAIN control is used to suppress radar returns
which are the result of radar signals reflected from rain
drops.
FTC performs differentiating, or filtering of rain clutter
Select SART ON in order to improve the detection of
search and rescue transponders.
Vary the pulse length from short to long in order to opti-
mize the target discrimination for the selected range
Select the interference function (ON or OFF).

Look for ALARM--Messages. (chapter 2.3.6.4).
Compare the position indicator on t he radar information panel
with the position s ensor.
Compare the radar video with the local area by making a bear-
ing to a known target such as a buoy, beacon or church.
Check the magnetron with the performance monitor. (Chapter
2.5.5).
PPI adjustments
Select the desired Range Scale (from 96.0 Nm, to value
0.125 Nm).
Fade the Range Rings. Rings are used to make quick
assessments of a target’s app roximate range from the
ship. The ship symbol appears in the range scale
between 0.125 Nm and 96.0 Nm or intheringscale
0.02 Nm and 16 Nm.
