PROBLEMS WITH NEW ES B-3

I HAVE JUST PURCHASED A NEW ES B-3 ENGLISH - SPANISH TALKING DICTIONARY,AND I AM HAVING A FEW PROBLEMS WITH IT.
THE FIRST PROBLEM IS WITH THE SPEECH FACILTY.THE VOICE SOUNDS LIKE A SLOWED DOWN RECORD AND IS IMPOSSIBLE TO UNDERSTAND.I CHECKED THE BATTERY WHICH SHOWED 100% POWER.I PUT NEW BATTERIES IN ANYWAY,BUT IT WAS JUST AS BAD.
THE OTHER PROBLEM IS CONNECTING TO MY PC.WHEN I PLUG IN THE USB CABLE I GET A MESSAGE SAYING THERE IS A FAULT AND IT WILL NOT CONNECT.I TRIED TO USE THE DESKTOP MANAGER BUT GOT A MESSAGE THAT THE DEVICE WAS NOT AVAILABLE.OTHER DEVICES WORK FINE ON THE SAME USB CONNECTION.IS THERE A DRIVER NEEDED TO MAKE THIS WORK.
I HOPE YOU CAN HELP WITH THESE PROBLEMS
YOURS MR J WADEMAN
