12 +Both have a battery capacity of around 30 days. The programming, operation, and downloading procedures for both types of SmartSolo nodes are also similar.

20 -Short term (~~30 day) battery powered nodes. The default gain should typically be set to 24 db for the Short Period 16HR-3C and 6 db for the Broadband BD3C-5. **This gain must be removed when exporting to miniseed.**
19 +ANU recommends that the SP 16HR-3C be set to a gain of 24db and no higher than 250 Hz sampling rate. The BD3C-5 should be set to a gain of 6db (maximum allowed). These are what we use for our internal experiments. **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.
