SD Card
An SD card is used for programming the operating system on the User Interface. Please refer to PROFIRE's PFNIX
Software Update Guide (http://3100.profireenergy.com/pf3100-documentation/) for detailed instructions on
programming and updating PFNIX software. The SD card should not be inserted or removed unless the area is
known to be non-hazardous, as doing so may cause a spark.
