The included 16GB microSD card is located on the left side of the TRACK E. Just pull out the lid and push the card in order to remove it. This card records up to 30 hours in 24-bit recording format and 23 hours in 32-bit Float recording format. Formatting the microSD card is easily done in the Setup App via Bluetooth. You’ll find it in the Settings section of the Setup App's menu.
Note: When using different microSD cards, make sure you use one that is qualified. Recommended are SanDisk/Western Digital 8/16/32GB or similar Class 10 SDHC up to 32GB. We recommend to leave the microSD card inside the TRACK E and use the device as a hard drive.
