10kW and 25kW Installation Manual
Introduction
This manual explains how to install the radar scanner (a pedestal) and the Navico
radar processor. There are also details how to connect the radar to the various brands of
displays produced by Navico.
This manual should be used in conjunction with the installation manual provided with the
display.
This manual is written for professional marine technicians, installation technicians, and service
technicians. Dealers may use information contained in this document.
The radar systems consist of a scanner, radar processor and connection cables. Scanner
models are available with power outputs of 10 kW and 25 kW to suit diff erent customer
requirements. Each scanner model has a corresponding radar processor module.
The radar system is intended for use in a marine environment. It consists of an open antenna
scanner connected to a radar processor module by a prefabricated interconnection cable. The
interconnection cable must be installed by a qualifi ed radar technician. An ethernet network
cable is used to connect the radar processor to the system display.
!
Warning:
The scanner cable should only be installed by a qualifi ed radar technician
!
Warning:
Use the radar at your own risk. Your radar is designed 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 confl ict arises between the
navigation data from your radar and data from other navigation aids, make sure you resolve
the confl ict before proceeding with navigation.
A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN NAVIGATION
INFORMATION.
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 ruled that the radar must be used, and the radar operator
must know all operational aspects of radar performance. Otherwise they will face a greater
risk of liability if an accident occurs.
!
Warning:
High Voltage Hazard
There are dangerously high voltages present within the radar pedestal 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.
