We recommend charging the player for 8 hours for the initial two charges.
Subsequent charges should only take 3-5 hours.
Inserting and removing the Micro SD card
Inserting: Ensure that the player is powered off, and disconnected from the
computer. Hold the Micro SD card face up (side with words aligned in the
opposite direction of the display screen), and slide the card into the socket on the
player, slightly past flush. When you hear the card click into place, you can
access the card.
Removing: Ensure that the player is powered off, and push the SD card just past
flush. When you hear the click, release pressure, and the card will slide out.
Caution: Please ensure that the power is off when you connect or disconnect
your SD card, or damage may occur to the player or your card.
