9.2 Installing the Scanner Unit
9.2.1 Selecting the installation location
The scanner unit shall be installed where there are not large obstacles in the
direction of the ship's heading line in the same plane.
If there is a large impediment in the same plane as the scanner unit, this may
cause the generation of folse echoes. In particular, if such folse echoes appear at
the ship's heading line, monitoring will be difficult and this may cause inadequate
forecasting of danger.
Do not install the scanner unit near chimney's or the exhaust of chimneys.
Soot will cause the performance of the radar to decrease and heat may cause
breakdown.
Do not install direction antenna or VHF antenna in the vicinity of the scanner unit.
Doing so may cause noise in the antenna reception.
Consideration should be given to separating the radar cable from the cables for the
direction antenna and VHF antenna.
These cables should never be bundled into one. Doing so may cause noise in the
antenna reception.
