Data Storage; Station Info - Gecko Compact Product User Manual

Data Storage

The Gecko is supplied with a 32GB SD card, formatted with the FAT file system. Larger
capacity SD cards can be used in the Gecko if they are pre-formatted as FAT (not exFAT).
To remove the card from a Gecko Compact 3ch (above, left) slide open the SD card cover
and press in the SD card to eject it. The SD card faces up, and it cannot be inserted upside-
down. For the Gecko Compact 4ch (above, centre), the SD card cover requires a quarter
turn anti-clockwise before removal. The SD card faces the rear of the recorder.
If you have a Rugged model with optional internal sensor, unscrew the card cover to access
the SD card slot (above, right). The SD card faces the rear of the recorder.
Insert the SD card into your computer (directly if you have an SD card slot, or via a USB
card reader) and you'll be able to browse your continuous data files.
To re-insert the card, check you have the correct orientation and do not force the
card if it does not insert easily. Push the SD card down into the socket, ensuring you
feel the card spring back from push-lock. The SD card will automatically mount and
recording should resume. Check that the q arrows are animating over the word "Storing"
on the Home screen, which indicates data packets are being written "down" to the SD card.

data format standard there are three tiers of identifier – Network, Station, and Location.
