The following tools are needed and provided in the bird deterrent kit:
|Fastener||2||Wing nut M6 DIN315 A2||1|
|Hex socket-head screw M6×16 DIN7991 A4||4||Allen key 4 mm||1|

The optional bird deterrent prevents birds from landing on the ceilometer which could interfere with the measurements. The bird deterrent consists of a metal structure that supports a piece of fluorocarbon line.
Open the back door of the ceilometer (the side where the measurement unit is) and
remove 2 screws and washers from both sides of the radiation shield cover.
Install the fasteners with the previously removed washers and screws.
Install the bars to the fasteners with the 4 screws.
Install the washer and wing nut, but do not tighten them yet.
Slide a fluorocarbon line through the designated loops, so that the ends of the line
meet at the thread of the bar.
Wrap the ends of the line 3 times around the thread, between the washer and the bar, and tighten the wing nut.
