9.3 Radar Unit
If operated in dusty conditions the control module, transmitter and receiver fibre optic sockets may become
dusty inside. In such conditions open the unit up on a regular basis and blow out or vacuum all the dust.
9.4 Antenna Electronics Connection Pins
Ensure that they are protected by leaving the antenna mounting block installed or by covering them with a
block of Styrofoam or, better still, removing them when transporting them.
9.5 Fibre Optics Cables
The fibre optic cables are the most fragile component in the system. They can be easily damaged by
misuse.
When handling the fibre optic cables always roll and unroll them as if they were on a spool. DO NOT roll
them around your arm like a rope or extension cord. Also, these cables do not twist, therefore laying the
roll on the ground and pulling the cable off will cause the cables to tangle.
