After switch-over to a smaller display-range, check whether a
better display is obtained by switching to a different pulse length.
Switching is done by clicking on the pulse length area (SP  =
Short Pulse, LP = Long Pulse).

Selection of the Antenna Revolution Rate
In order to increase the update rate of the radar video, the antenna
revolution rate can be doubled
 1)
Switch-over is achieved by clicking on the HSC  area (HSC = High
Speed Craft; "HSC on" = doubling of the antenna revolution rate).
A disadvantage of the high revolution rate of the antenna is the
unavoidably higher rate of wear and tear on the antenna
gearbox.
On vehicles classified as High Speed Craft, the high revolution
rate is a legal requirement. Therefore, on such vessels, the possibility of switching over to the lower
revolution rate is not provided.
1)  
If the appropriate antenna gearbox is installed. Switching over is possible if the HSC area is present.
