# Inserting and Removing Micro-SD Cards from the TT System Unit

To insert the micro-sd card, insert the micro-sd card with the metal strips down as shown below.  Then push the card into the slot.  Note that the card should be pushed straight in.

To remove the micro-sd card, place your fingers over the edge and pull it the card straight out.   Note that there is no "spring action" on this device; simply pull to remove, don't push and pull.
