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 device 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.
Understanding the Power Save Feature
If your device is unable to find a signal after 15 minutes of searching, a Power Save
feature is automatically activated. If your device is active, it periodically rechecks service
availability or you can check it yourself by pressing any key.
Anytime the Power Save feature is activated, a message displays on the screen. When a
signal is found, your device returns to standby mode.
Maintaining Your Device's Peak Performance
For the best care of your device, only authorized personnel should service your device
and accessories. Faulty service may void the warranty.
There are several simple guidelines to operating your device properly and maintaining
safe, satisfactory service.
• Hold the device with the antenna raised, fully-extended and over your shoulder.
• Don't use the device if the antenna is damaged.
• Avoid exposing your device and accessories to rain or liquid spills. If your device does
get wet, immediately turn the power off and remove the battery. If it is inoperable, call
Customer Care for service.
