Furuno USA Inc 9ZWRTR064A Manual De Usuario

• The antenna unit is installed either on top of the wheelhouse or a platform on the radar mast. 

Install the antenna unit where there is a good complete view. Any obstruction causes blind sec-
tors. For example, a mast with a diameter smaller than the horizontal beamwidth of the radiator 
causes only a small blind sector. A horizontal spreader or crosstrees in the same horizontal 
plane creates a large obstruction. Install the antenna unit above, or below a horizontal spreader 
or crosstrees.

• You cannot put the antenna unit where there is a completely clear view in all directions. Make 

sure you check for blind sectors on the radar screen after you have installed the radar.

• To reduce the electrical interference, do not run the signal cable near other electrical equip-

ment. Also do not run the cable in parallel to power cables.

• A magnetic compass gives error if the antenna unit is installed near the magnetic compass. 

Follow the compass safe distances shown in the SAFETY INSTRUCTIONS to prevent the 
interference to a magnetic compass.

• Do not apply paint to the radiator aperture. The radar wave cannot be transmitted if there is 

paint on the radiator.

• If this radar is installed on a large vessel, follow the points shown below:

• The length of the signal cable between the antenna unit and the display unit is max. 30 m.

• The output from a funnel or exhaust vent decreases aerial performance and hot gases can 

damage the radiator. The antenna unit must not be installed where the temperature is more 
than 55

° C.

• The antenna unit can be installed on the bridge, a common mast, or the radar mast.
