Troubleshooting
I need to insert my SIM card
1. Remove the battery door and battery.
2. With the metal contacts facing the battery
compartment, slide the SIM card into the cutout in the
lower-right corner of the compartment until you feel it
snap into place. Align the notches to make sure you
have the card oriented correctly.
3. Reinsert the battery and battery door.
My touchscreen appears blank
1. If you’re on a call, when the time period specified in
Backlight Settings expires, the screen dims. Press any key
(except Power/End) to restore the normal brightness.
2. If you are not on a call, when the time period specified in
Backlight Settings expires, the screen dims. Press any key to restore the normal brightness. One
minute after the screen dims, it turns off. Press and release Power/End to wake up the screen.
3. If you can see a dim image on the screen, press Option + P and then press Left and
Right to adjust the brightness. When finished, press OK .
