326 Section 7A: Help
Screen
The Screen Appears Blank
1. When the time period specified in Backlight Settings expires, the screen
dims; one minute later, the screen automatically turns off. (Press any key
except Power/End to wake up the screen. Pressing Power/End hangs up the
call.)
2. Look closely at the screen. If you can see a dim image, try adjusting the
screen brightness (see “Adjusting the Brightness” on page 281).
3. If that doesn’t work, perform a soft reset (see “Performing a Soft Reset” on
page 320).
4. If that doesn’t work, connect your smart device to the AC charger (see
“Charging the Battery” on page 13) and perform a soft reset again.
5. If that doesn’t work, perform a hard reset (see “Performing a Hard Reset” on
page 321).
Tip:
Make sure that third-party applications support 240x240 screen
resolution. Some older applications have screen-size limits.
