Health and safety information
If your phone is unable to find a signal after 15
minutes of searching, a Power Save feature is
automatically activated. If your phone 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 phone returns to standby mode.

• Hold the phone with the antenna raised, fully-
extended and over your shoulder.
• Try not to hold, bend or twist the phone's antenna.
