Understanding the Power Save Feature
If your phone is unable to find a signal after 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.
Understanding How Your Phone Operates
Your phone is basically a radio transmitter and receiver. When it's
turned on, it receives and transmits radio frequency (RF) signals.
When you use your phone, the system handling your call controls
the power level. This power can range from 0.006 watts to 0.2
watts in digital mode.
Maintaining Your Phone's Peak Performance
For the best care of your phone, only authorized personnel should
service your phone and accessories. Faulty service may void the
warranty.
There are several simple guidelines to operating your phone
properly and maintaining safe, satisfactory service.
• To ensure that the Hearing Aid Compatibility rating for your phone is
maintained, secondary transmitters such as Bluetooth and WLAN
components must be disabled during a call. For more information,
refer to the “Disabling Bluetooth or WLAN” section.
• If your phone is equipped with an external antenna, hold the phone
with the antenna raised, fully-extended and over your shoulder.
• Do not hold, bend or twist the phone's antenna, if applicable.
• Do not use the phone if the antenna is damaged.
• If your phone is equipped with an internal antenna, obstructing the
internal antenna could inhibit call performance.
• Speak directly into the phone's receiver.
• Avoid exposing your phone and accessories to rain or liquid spills. If
your phone does get wet, immediately turn the power off and remove
the battery. If it is inoperable, call Customer Care for service.
