WATER INGRESS
Although the waterproof rating capacity of this product exceeds that called for by the IPX6 standard,
water intrusion and subsequent equipment failure may occur if the transceiver enclosure is subjected
to commercial high pressure washing. Kelvin Hughes Ltd will not warrant equipment subjected to high
pressure washing.
EMC INSTALLATION GUIDELINES
The X-band 12kW transceiver system conforms to the appropriate Electromagnetic Compatibility
(EMC) regulations, to minimize electromagnetic interference between equipment and minimize the
effect such interference could have on the performance of your system.
Correct installation is required to ensure that EMC performance is not compromised.
For optimum EMC performance we recommend that wherever possible the equipment and cables
connected to it are:
At least 1m from any equipment transmitting or cables carrying radio signals e.g. VHF radios,
cables and antennas. In the case of SSB radios, the distance should be increased to 2m.
More than 2 m from the path of a radar beam. A radar beam can normally be assumed to spread
20 degrees above and below the radiating element.
The cables supplied and specified for the equipment are correctly fitted and used.
Cables are not cut or extended, unless doing so is detailed in the installation manual.
NOTICE
Where constraints on the installation prevent any of the above recommendations, always ensure
the maximum possible separation between different items of electrical equipment, to provide the
best conditions for EMC performance throughout the installation
SUPPRESSION FERRITES
Cables supplied with the equipment may be fitted with suppression ferrites. These are important for
correct EMC performance. If a ferrite has to be removed for any purpose (e.g. installation or
maintenance), it must be replaced in the original position before the product is used.
Use only ferrites of the correct type as supplied with the cables.

Declaration of conformity
The X-band 12kW transceiver and open Array radar scanners are in compliance with the essential
requirements of R & TTE directive 1999/5EC.
