Other Important Safety Information

Product Performance
Getting the Most Out of Your Signal Reception
The quality of each call you make or receive depends on the signal strength in your area. Your phone informs you of
the current signal strength by displaying a number of bars next to the signal strength icon. The more bars displayed,
the stronger the signal.
If you're inside a building, being near a window may give you better reception.
