3.6 Measures for the Electromagnetic Interference<br />
The equipment needs to be installed properly in order to ensure its successful operation even though it has<br />
been designed to satisfy the requirements stipulated by the electromagnetic compatibility (EMC) requirements.<br />
Several factors that can affect the equipment performance are shown below.<br />
3.6.1 Checks before the Connection<br />
Observe the following instructions to avoid possible electromagnetic interference when connecting a cable<br />
(Antenna, Display unit, Radar or Power supply cable) to the equipment.<br />
• Keep this equipment away from another equipment (minimum of 1 meter) that is transmitting high frequency<br />
signals or any cable transmitting such signals. Some examples of such equipment include the VHF transmitter<br />
and receiver and antenna cable. Keep a minimum distance of 2 meters in the case where the equipment<br />
needs to be installed near a SSB transmitter/receiver.<br />
• Keep the equipment away from the radar beam by a minimum of 2 meters.<br />
In general, for this purpose, the radar beam is understood to be covering from its source in the range of 30<br />
degrees above and below its center axis (a total of 60 degrees).<br />
• Do not use the same power supply to start the engine as the power supplied for this equipment.<br />
The equipment may be reset if its power supply voltage drops below DC <strong>10</strong>V, which in turn may result in the<br />
loss of some data or change in the operation mode even though the equipment itself will not be damaged.<br />
• Use only the cables specified by us. The cable may fail to satisfy the EMC performance requirements if it is<br />
cut or reconnected after cutting. Thus, the cable should never be tampered with unless otherwise specified<br />
in the instruction manual.<br />
3.6.2 Checks before the Navigation<br />
• Check the equipment before starting navigation that it is free from any problems related to radio communication,<br />
starting the engine, battery voltage, and so on.<br />
• This equipment may be affected by such external factors. In general, the equipment will not be damaged<br />
due to such external factors, however, it may be reset or malfunction momentarily or inaccurately.<br />
