F2 E0 is a shorted keypad. Replace the keypad which is your entire touch pad. In rare cases your ERC or electronic range control can also be bad, unlikely though. Hopefully this is still under warrantee as the part alone is over 150.00. I recommend you have a technician replace this as most parts houses will not warrantee a electical part if a customer installs it. Good Luck, Appliance Specialists.

can not measure distance.
each time the button is pressed dist, 279 error appears.

Try your SIM card in another phone. If it still doesn't work then you need a new SIM card. If the SIM card works then try cleaning your contacts by rubbing them lightly with a clean pencil eraser. Ensure all your contact pins are straight and in a uniform position.

your player has the firmware of share type which uses it for your pc so load only 150 songs
