• Goodmorning, I received Slick HP921 Wireless Headphones yesterday I have perfectly utilized them yesterday but today I have no communication between the wireless transmitter and the wireless headphones without changing anything since yesterday.
  The wireless transmitter is turned on but it's not trasmitting. The headphones work perfectly with fm mode and also when i connected the single green plug with other devices ( pc, phone ).
  The problem should be in the wireless transmitter.
  What I have to do ?
  

hello there have found a way to fix your problem for i am having the same problem.

my e-reader is frozen and want turn off. I can even read my book. Help

shut down the PC and turn out your mp3, then do a antivirus for your mp3 after plug it into the PC and before open the folder.

you need to by a new battery

The manual for a 4Gb slicK player states: turn the power switch to "on" and hold down the play/pause button until the unit powers up. You can also power down the unit in the same way, (while leaving the switch in the "on" position).

Simple...use a separate card reader.

Anyone out there knows about these slick mp4 2gb players I need some help my player just lost all the files and music I had on it

All you need to do is set the power switch to 'on' and hold in the play button til the player turns on.
