SOURCE: I DON'T KNOW TO START THE MP3 MP4 T.sonic 840 PLAYER

I'm using T sonic 840. For the first time even I don't know how to operate.
Now I know every nook and corner about T sonic 840

When you start charging The animation appears,
When you switch off the charging, you can see goodbye animation.

Now you press the play button for four to five seconds, and the T sonic will be switched on.
I just want to let you know the functionality of the scroll button.
You can scroll down, scroll up and even you can press the button like play button and record button.

When switched on the page will be at Music.
Now just press the scroll button, now the mp3 player will be started.


Cheers...!!!

You can either it either using a USB cable or through the wall charger. You should have both as part of the package with your player. Do you have time? Or is your problem something more than that?

If it's an iPod, Apple makes an AC power adapter. It's a little expensive at $40, but it's very small and portable. If it's not an iPod, one of those universal chargers should work.
