Connect the Walkman to a computer or AC adaptor and charge it for about 10 minutes. If the problem persists, restart the Walkman.
[A]: Charge lamp
[B]: USB cable
NOTE: The charge lamp lights up in red soon after the Walkman is connected to a computer or AC adaptor, but the Walkman screen may not turn on if the battery level is insufficient.
If you wait for about 10 minutes with the Walkman connected to the power source, the Walkman will turn on and enter the standby mode automatically.
If the Walkman does not turn on even 10 to 20 minutes after the charge lamp lights up in red, restart the Walkman.
