Safety and usage information
103
Understand 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.
Allow only qualied personnel to service your
device
Allowing unqualied personnel to service your device
may result in damage to your device and will void your
manufacturer’s warranty.
Ensure maximum battery and charger life
• Avoid charging batteries for more than a week, as
overcharging may shorten battery life.
• Over time, unused batteries will discharge and must be
recharged before use.
• Disconnect chargers from power sources when not in use.
• Use batteries only for their intended purpose.
Avoid interference with other electronic
devices
Your device emits radio frequency (RF) signals that may
interfere with unshielded or improperly shielded electronic
equipment, such as pacemakers, hearing aids, medical devices,
and other electronic devices in homes or vehicles. Consult
the manufacturers of your electronic devices to solve any
interference problems you experience.
Important usage
information
Signal strength
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.
