What to do if the unit does not respond? 1. A Reset button is available on the side of the unit, inside the hole, located next to the Back button.
- This Reset button is a helpful tool because it can provide an immediate restart of the E-Ceros Revolution tablet. You can press this button using a thin tool such as a paperclip. After pressing the reset button, simply turn on the device and you’re ready to go.
- This reset and refresh can be opportune when:
There are many applications running at the same time and the device slows down too much and does not respond for a long time When an application causes a malfunction or freezes the tablet.
Can I easily restore default factory settings? 1. Sure. If you desire to return to the default factory settings, then you need to perform factory data reset. 2. Factory data reset option can be found under Settings > Backup & reset menu. 3. The factory data reset formats the data partitions so all user data will be deleted. Keep in mind to backup your data first as factory resetting will delete all data stored.
