Where can I find a tutorial for NU Dolphin TOUCH Pro waterproof mp3 player?

Your rough on headphones. Get a pair with Strain relief ends that are protected and stay in place when twisted or roughed up. More expensive headsets take in consideration the treatment the phones will be given and usually build them accordingly.

Hi martacornet...
Go to the following webpage and download and intall the firmware (driver) you need, there is also a user manual there at the same webpage..

send it back for a warranty refund as it is defective
you do anything and the warranty is void

Well maybe it doesn't speak dolphin, please be a little considerate

download software from manufacturers web site then try connecting.

I will advice you to try resetting your device but I do't think there is a reset hole on it.
Before having your device checked at a support center try to make sure you have charged the battery for enough time then check the troubleshooting guide for this device at:

Did you get it on ebay? My player has the same issue... And it seems to me that the seller knew about it. I haven't found a solution yet, but will probably sent it straight to NU as there is a warranty.

did you ever get a solution?i do have the same problem!
