Assembly Cable #3
How do I put Cable #3 back into the socket?
What you need to do is take the cable labled #3 with some tweezers and very carefully insert it into its outlet but make sure that the little latch is flipped up. when you get the cable in there flip down the latch and it will be locked in there. after that you can plug in #2 and then #1 and then close the device up and check to see if it works
Make sure the plastic clip is pulled back and with your nail or a spudger push the cable back into the socket and flip down the black plastic securing clip.
