Potentially capable of housing much larger batteries than the TSAWR due to the larger cavity space. 240 240 241 +We have found that the older LPR SD card slots can sometimes fail such that the data cards prematurely "pop out" during recording, which can be catastrophic. This seems to mostly occur in periods of hot weather, but not always. We have developed a small add-on that screws into the nearby serial port that effectively holds the cards in place and will ship included with these loggers. Screw the device in firmly, then **gently** slide over a pre-inserted card until it is flush with the top of the card. It probably won't slide over all the way and that's by design. Take care not to force the depress the card inadvertently (although testing has shown it will still record). 242 + 243 + [[image:LPR_card_adaptors.jpg||alt="image of the LPR SD-card adapter"]] 244 + 241 241 = ANU "ANUSR" (Gen 1, 2003? - 2012) = 242 242 243 243 This logger has been retired for a long time and has a different instrument response.
