24 24  The GPS antenna is at the top and center of the unit, and will (usually) only receive signal with a clear sky view directly above. The signal is able to penetrate plastic and terracotta planters and a thin layer of soil, but may struggle if the soil layer is too thick. The BD3C will not start recording without first attaining a GPS lock.

28 28  Use a (**landfill**, not //compost//) degradable bag when installing to keep the instrument clean. This will save you many hours of time cleaning them in preparation for their return. [[Here is a video>>http://auspass.edu.au/field/bd3c_removal.mp4]] demonstrating its effectiveness.

130 130  Then open the “SoloLite” software, and just go to “File” to make a new project. In this case, you do not need to find the exact 16 nodes that were grouped for script writing. Do not worry about the settings for the seismic recordings for the next window to pop up, as the only way to reset the instruments (e.g., sampling rate, gain etc) is to write script to re-program them.

135 135  Once you create the new project, your Data Transfer View panel on the bottom right of the window will show these nodes that have properly connected to the data harvest, including series number, data size etc. It is okay if the “Prospect not matched”, which simply means the project you just created does not match the one you made to program them. Simply select all these nodes, and right click to “force download”, which will initiate the downloading process. Once they are done, you will see new folders created for each slot at your Downloaded Data panel on the top left of the window.

One thing to note is that the “Sample Interval” must be set exactly to this used to reset the nodes. Once you are done with the setting, click “prepare” before “run”. If everything works correctly, you should see the reformatting process from the small panel on the bottom left of this popped up window.
