4.3 Mounting instructions
The radar emits pulses of electromatic waves which are polarized. By adjusting rotation of the
instrument the polarization can be changed to reduce false echoes.
The narrow portion of the radar signal is in the middle of the printed label on the instrument. This
should be pointed towards the center of the vessel or any obstacle that may cause any unwanted
reflection to minimize false echoes, for example the sidewall or vessel structure.
