8 -* If possible, choose a location with minimal noise interference and as far away from traffic and people as possible. Try to keep your station out of sight to avoid theft or tampering. The site should not be installed in a place where people would ever stumble upon it (e.g. a walking trail or public area).
9 -* Nearby Trees, bushes, power poles etc can induce low period noise in your data when they sway in the wind. A rule of thumb is to have your sensor at least as far away from these as their height.
10 -* Cattle and stock can and will destroy your site. NEVER EVER install a station where cows can get to it.

10 +* Cattle and stock can and will destroy your site and our instrumentation. NEVER **EVER** install a station where cows can get to it because they //will// get to it and they **WILL** destroy it.
11 11  * If the area looks like a place that has flooded, or may flood again, absolutely assume that it will. This very much includes dry riverbeds or ponds. Always prefer locally elevated terranes.
12 12  * The harder the soil, the better the signal. Sand and mud are your enemy.
13 -* Grass can often grow high enough to block your solar panel from sun. If possible, clear an area in front of the panel to minimize this possibility.

19 19  * Ensure the sensor is leveled correctly, typically the sensor can be placed on a well leveled paver to make this easier.
20 -* Orient the sensor correctly using a compass, paying special attention to the north direction and accounting for declination.
20 +* Orient the sensor correctly using a compass, paying special attention to the north direction and **accounting for declination**.
21 21  ** When using a compass to orient the sensors, ensure it is kept away from metal objects or structures that could interfere with its magnetic field.
22 -** It is recommended to take a picture of the sensor's orientation next to the compass.
22 +** It is recommended to take a picture of the sensor's orientation next to the compass in case there are questions or issues later.
23 23  * Hold the sensor or sensor covering securely while infilling and compacting the hole to ensure the setup is kept in the correct position (level and oriented).
24 24  * Burial styles can vary depending on sensor type, soil, wetness/humidity and the duration of the experiment. See the **Sensor Protection** section below for more detail.

46 46  * Use wire to secure the fence to the post and also the solar panel to the fence.
47 47  * 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 pliers to make the final twist in the wire so that it is **really tight**.

51 -* 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?
52 -* 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.
53 -* 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.
51 +* In fire-prone areas, clear a perimeter around the installation to reduce fuel sources. Assume the area will catch on fire~-~- will your site survive?
52 +* Consider using fireproof covers for the logger. This will have the added benefit of reducing soil contact, especially dirt getting into SD card slots. A permeable cover will avoid trapping rainwater ~-~- a problem associated with plastic tarps, which damages the logger and attracts insects/animals (ants, centipedes, snakes, etc.). We are still testing materials for suitability in the field (e.g., safe and tolerable degradation in the environment).
53 +* We recommend adding a soil layer for insulation. This seems to keep loggers cooler, reduce fire damage, and discourage interference by people passing by.

57 -* 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.

58 58  * Document the installation process, including sensor types, **serial numbers**, orientations, high quality latitude/longitude coordinates, elevation, and system configurations, along with fire safety measures implemented.
59 -* Draw a map or at least take a google maps screenshot with some drawn annotations so others can find the site.
