I have a candy cdcf 6 that shows an errorcode shortly after starting. It bips and "3in1" blinks. What do I do?

Question

The &quot;3in1&quot; light blinks and it makes bip-sounds. Thank you to anyone who can help me <img alt=":)" class="bb-smiley" src="/media/com_easydiscuss/images/markitup/emoticon-smile.png" />
