Digital radar dimensions
CAUTION:
If two digital radars are installed at different locations in a dual
radar system, care should be taken to allow for the difference in
position of the radars when switching between the two on your
display, this is especially noticeable at short ranges on larger
vessels.
Selecting the best location for the digital radar unit requires careful
consideration of the following points, to ensure reliable and trouble
free operation:
Note: In order to minimize potential interference to other systems on
board ship (EMC), it is advisable to mount the digital radar on a part
of the boat that is insulated from the ship’s battery negative. If you
cannot do this, and encounter problems, you can fit insulating
bushes between the digital radar and its mounting bracket.
