9.1 General
Proper installation of a radar unit is essential for extracting full capability of the unit
reliably and for facilitating troubleshooting and maintenance. Follow the guidelines
given below when installing the radar unit.
(a) Install the scanner unit as high as possible while taking its weight into consideration.
(b) Install the display unit in the wheel house for comfortable observation.
(c) The scanner unit and display unit are connected by 10 to 20 m compound cable with 20
