Hearing Aids
Some digital wireless phones may interfere with some hearing aids. In the event of such interference, you
may want to consult your service provider, or call the customer service line to discuss alternatives.
Nonionizing Radiation
Your device has an internal antenna. This product should be operated in its normal-use position to ensure
the radiative performance and safety of the interference. As with other mobile radio transmitting equipment,
users are advised that for satisfactory operation of the equipment and for the safety of personnel, it is
recommended that no part of the human body be allowed to come too close to the antenna during
operation of the equipment.
Use only the supplied integral antenna. Use of unauthorized or modified antennas may impair call quality
and damage the phone, causing loss of performance and SAR levels exceeding the recommended limits as
well as result in non-compliance with local regulatory requirements in your country.
To assure optimal phone performance and ensure human exposure to RF energy is within the guidelines set
forth in the relevant standards, always use your device only in its normal-use position. Contact with the
antenna area may impair call quality and cause your device to operate at a higher power level than needed.
Avoiding contact with the antenna area when the phone is IN USE optimizes the antenna performance and
the battery life.
