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.
