Warnings and Cautions

Caution:

Use the radar at your own risk. Your radar was designed for use as a navigation aid. It should not be used for purposes that require precise measurements of direction, distance, topography or location. Always compare the navigation information received from your radar with data from other navigation aids and sources. When a conflict arises between the navigation data from your radar and data from other navigation aids, make sure you resolve the conflict before proceeding with navigation. A CARE-

FUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN NAVIGATION INFORMATION.

Caution:

International Regulations for Preventing Collisions at Sea mandate that when radar is on a vessel, the radar must be used at all times, regardless of weather conditions or visibility. Numerous court decisions have not only ruled the radar must be used, but that the radar operator must be knowledgeable in all operational aspects of radar performance or otherwise face a greater risk of liability if an accident occurs.

WARNING: High Voltage Hazard

Dangerously high voltages are present within the radar scanner unit. Technicians must exercise extreme care when working inside the unit. ALWAYS remove power before removing the cover. Some capacitors may take several minutes to discharge, even after switching off the radar. Before touching the magnetron or any high voltage components, ground them with a clip lead.

WARNING: Microwave Radiation Hazard

The microwave energy radiated by a radar antenna is harmful to humans, especially to the eyes. NEVER look directly into an open waveguide or into the path of radiation from an enclosed antenna. Radar and other radio frequency radiation can upset cardiac pacemakers. If someone with a cardiac pacemaker suspects abnormal operation, immediately turn off the radar equipment and move the person away from the antenna. Turn off the radar whenever it is necessary to work on the antenna unit or other equipment in the beam of the radar.

RIM 300 Installation

The RIM 300 will replace the power cable that came with your display unit. Your RIM 300 has three cables branching out from the cable plug, which include: radar data cable, display unit power cable and NMEA 2000 power cable.

NOTE:

You will need to purchase a SIMRAD heading sensor for the Radar Overlay feature to work properly.

You MUST remove the power cable that came with your unit and replace it with the RIM 300 to complete this installation.

WARNING:

Even though the RIM 300 is replacing your original power/data cable, you must follow the same rules, cautions and warnings for powering the display unit and a NMEA 2000 network or LGC-3000 antenna module. These details are described in the display unit manual and the LGC-3000 instruction sheet. Failure to follow all power connection instructions and fusing requirements could result in damage to your equipment and injury to you.
