Try these steps if you have issues with your eReader.

1. EOkuyucunuzu kapatın ve ardından tekrar açın.
2. Force your eReader to shut off: If your screen is frozen, press and hold the power button for 10 seconds. Your eReader should turn off. Turn it back on and see if the issue was fixed.
3. Charge your eReader: Turn your eReader off and charge it for at least one hour.
