My device screen went blank! What happened?
When you receive your device, two settings are “on” by default: Key Guard and Power-Saving mode. What this
means is that if your device is idle (you haven’t pressed any keys or buttons) for 5 minutes, key guard will begin
(pressing keys has no effect in key guard). If 30 minutes passes and you’re still in key guard (idle), your screen
will “blank”, which means it has gone into power-saving mode.
To wake your device and unlock the screen from key guard, press + .
You can change these default settings by following the instructions in:
•
Battery & Backlight
on page 38
•
Key Guard & Security
