If this message persists no matter how long you charge the device then it is an indication that the battery has failed. Your best bet would be to contact Transcend for repairs.

No memory availability is appearing .it's showing 0kb memory

I using T sonic 840.
I found the reason for this.

I think you used transferred the songs/ videos from the computer, which had Windows operating system.

Windows has the high possibility to attack your T sonic by means of Viruses and worms.

So, first take a back up of your songs/videos/photos/text documents.
then format it.

Now download the songs/videos/photos/text documents. and before removing your device.
Scan for virus. If you find any virus fix that virus.

Now you cannot see the 0kb free space.

Starting problem

Have you pressed in the reset button on the side with a pen (or similar) until you heard or felt a click and held it in for a few (3-5) seconds, while unattached to a computer?

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.

USB drive not recognized

I had this problem. The T.sonic supplied USB cable was faulty and when I used a quality cable the problem was resolved. If you have a USB cable that came with a digital camera it will do the job as well.
