APPENDIX
Reset vs. Factory Reset
Reset:
1. Press and hold down the power button (approx. 5 seconds) on the remote commander until the message "Power off" appears on the
TV screen
2. The TV will turn off, and then restart automatically
Try a reset when Android TV doesn't behave properly (e.g., the TV is unresponsive or is stuck on a black screen). Note if you unplug and plug in
the power cable, it may have the same effect as a reset. If a reset does not resolve the problem, try a new software update and or a factory reset.
Important: This reset will not delete any personal settings, data and downloaded apps on the TV.
Factory reset:
1. From Home Screen, select [Settings]
Select [TV] [Storage & reset]  [Factory data reset]  [Erase everything]
2.
3. Select "YES"
Important: The factory reset will delete all personal settings, data and downloaded apps on the TV.
Tip: We recommend creating a backup of the channel list onto a USB stick. This will allow to easily restore the channel list after performing a
factory reset. The following steps detail how to back up the channel list:
1. Connect the USB device to the TV so as to import/export the list of tuned programmes
2. From Home Screen, select [Settings]
Select [TV] [Channel setup] → [Digital setup] → [Technical Set-up] → [Programme List Transfer], then select [Import] or [Export]
3.
4. Follow the on-screen instructions to complete transfer
Force Factory reset:
1. Unplug the power cable from the outlet
2. Press and hold down both the "Center" and "Down" keys located on the TV
3. Plug the power cable back in the outlet (while holding down both the "Center" and "Down" keys)
Important: The factory reset will delete all personal settings, data and downloaded apps on the TV.
