23 23  ** It is recommended to take a picture of the sensor's orientation next to the compass.

40 +* You'll have to know a priori where north is as that is where you want to point the solar panel towards //(in the Southern Hemisphere, anyway)//
41 +* Pound in the star picket fence post well away from the sensor hole, and slightly north of it. You will want to then put the fence through the star picket so that it is on the NORTH side. This lets techs "flip up" the fence from behind for easy access.
42 +* Use wire to secure the fence to the post and also the solar panel to the fence.
43 +* Place the solar panel as high on the fence as possible to reduce any interference from grass and weeds. When securing the solar panel to the fence with wire, make the wire as tight as possible to reduce "rattle" in the wind. Test yourself. It's usually a great idea to use a pair of pliars to make the final twist in the wire so that it is **really tight**.

47 +* In bushfire-prone areas (e.g. everywhere in Australia), where possible a wide perimeter around the installation to reduce fire risk. Assume the area WILL catch on fire~-~- will your site be OK?
48 +* Use fireproof blankets to cover equipment. This also keeps the loggers clean and keeps dirt our of the card slots etc. Fire blankets are also permeable, unlike tarps, which avoids trapping rainwater around the logger attracting ants, centipedes, snakes, and other insects/animals.
49 +* We also recommend burying the data loggers with some dirt as this keeps them cool, further reduces the chance of fire damage, and keeps people from snooping around in them.

53 +* Documenting site installs and service information is not just a good idea, but **REQUIRED** as part of your ANSIR agreement. You are expected to take proper site logs.. trust us, it's for your own good. Failure to do so may result in ban for future loans.
54 +* Document the installation process, including sensor types, **serial numbers**, orientations, high quality lat/lon coordinates, and system configurations, along with fire safety measures implemented.
55 +* Draw a map or at least take a google maps screenshot with some drawn annotations so others can find the site.

57 57  Sensors can be covered with a PVC pipe to help prevent degradation of the components (i.e. sensor casing and cable connections), however, some sensors are made for direct burial (no protection). When installing a sensor, only use these two options. Do not try to protect the sensor via any other means such as a plastic bag or moisture absorbers & desiccants.
