 All installations should facilitate protection of equipment, including cabling, from
damage.
 The cables should be kept as short as possible to minimize attenuation of the signal.
 Crossing of cables should be done at right angles(90°) to minimize magnetic field
coupling.
 Install the radar cable as far as from the cables of other radio equipment in order to
prevent other radio equipment from interfering with the radar operations. Especially
inter-wiring cables between scanner unit and display unit of the radar should not be
run parallel with the cables of other radio equipment.
 Cable should not be exposed sharp bends.
 Ensure that the equipment is grounded.
 After installation
After you have completed the installation work, make a installation report with your
signature and explain it to the customer.
Then request him to keep the report on board a ship.
The installation report is now available for download on the our Marine Service
