To prevent blurring of the video, the mode "TM Mode" and "North-Up" or "Course-Up" should be
switched on.

2.
To reduce the risk of loss of target, the CLEAN SWEEP function must be switched off. The risk of
loss of target is also increased by fast course-manoeuvres performed by own vessel.

Target tracking must already begin at long range. In this connection, it must be noted that the target
data are correspondingly less accurate - see

Radar Setting for the Display of RACON Codes
The code of Racons consists of a radially arranged dash-dot code which begins in the radar video a short
distance behind the beacon position. By means of different codes described in the Lists of Lights, the
approach points equipped with Racons can be clearly identified.
distance behind the beacon position. By means of different codes described in the Lists of Lights, the
approach points equipped with Racons can be clearly identified.
Most Racons transmit in the X-Band, but there are some Racons installed which transmit in the S-Band.
The majority of Racons change their transmission frequency slowly throughout the entire frequency band,
and so they are not received in every revolution of the antenna.

For the setting of the radar, the same basic principles are applicable as for SART detection.

Radar Setting for SART Detection (X-Band only)
The information needed for reliable detection of SART’s is described in IMO Circular 161. The content of

Suppression of the Synthetics and Video
Suppression of Synthetics
So that a video signal which has a synthetic image (e.g. a target
symbol) superimposed on it on the PPI can be assessed more satis-
factorily, the display of the entire synthetics can be suppressed. This
occurs for as long as the DO key is kept pressed in the SYNTH OFF
area.
