My S0-20 does not turn on.

Try the following:

• Take out the battery, put it back in, and press the Power (Hang Up) key again.
• If that doesn't help, charge S0-20 for 30 minutes and then press the Power key.
• If the charger is not working, try connecting the USB cable directly into S0-20, or try charging S0-20 with a standard USB mini cable to charge it through your computer.
