The microSD card must be removed using the spring loaded “push-pull” mechanism on the
microSD socket. Forceful removal of a microSD card will result in permanent damage to the
socket that is not covered under warranty. To insert the card, push it into the socket until a
“click” sound is heard. Similarly, to remove the card, push the card into the socket. The push-
pull mechanism will “click” again and eject the card from the socket. The card is now
available for safe removal.
