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.
Do not touch or hold the antenna
area unnecessarily when placing
or receiving a phone call. 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 optimises the antenna
performance and the battery life.
