18 -We recommend that the SP 16HR-3C be set to a gain of 24db and no higher than 250 Hz sampling rate unless there is an explicit reason to do so. The BD3C-5 should be set to a gain of 6db (which is the maximum allowed). These are what we use for our internal experiments.
18 +The nodes must be programmed in the SoloLite software prior to use. Screenshots for the short period 16HR-3C and broadband BDC3-5 are shown with our recommended parameters.

20 -**Note that this gain must be removed when exporting to miniseed, **otherwise amplitudes will be a factor of either 15.84893192 (24db) or 2 (6db) too high. We also recommend disabling bluetooth to increase battery life, and to enable "FIFO" mode just in case old data is still present on the units and you run out of space (although it is unlikely you will go over 64 Gb for one deploy). If using the "timed turn-on" option, please be aware that **the units will not begin recording until they have acquired a GPS lock**, which may nor occur if they are buried too deeply or have very poor sky view.

23 +
24 +FIFO (first in, first out) data mode is safest as this will overwrite old data in case you forgot to clear the storage. At <= 250 hz you can fit 4++ months of data on these, shouldn't be an issue.
25 +
26 +Be sure to set the channel types to Seismic and the gain appropriately. For active source (i.e. explosions) you can leave the gain at 0, but for passive experiments some gain is purported to be helpful (although we have found this to be somewhat negligible). We can confirm that 6db for the broadband nodes and 24db for the short period works well.
27 +
28 +If you want recording to begin immediately, ensure that begin date is in the past by at least a few days. If you prefer to have a timed turn-on, then set the times as needed. **Be warned that recording will not begin until a GPS lock is achieved, so if you set it to a future turn-on but bury it too deeply, it may not record!**
29 +
30 +In newer versions of the software there is a "power consumption" setting.. we are no sure what this does exactly, but the manual says it gives life a "boost" at the expense of about 3 db of resolution. Until this can be quantified a bit better it is not recommended.
31 +
32 +Storage type can be DLD (proprietary) or Miniseed. We assume the software works best with their proprietary format so prefer not to risk any issues. You can export to miniseed later.
33 +
34 +GPS is best set to cycle mode (e.g. once per hour) instead of constant "always on". The clock drift on these are almost nil even if there is no sync at all, so it's best to conserve power.
35 +
36 +Bluetooth (BB nodes only) should be turned OFF to conserve power.
37 +
38 +We recommend that the SP 16HR-3C be set to a gain of 24db for passive experiments and no higher than 250 Hz sampling rate unless there is an explicit reason to do so. The BD3C-5 should be set to a gain of 6db (which is the maximum allowed) for passive experiments (or 0 db if active).
