GPS/Location based functions
Some products provide GPS/Location
based functions. Location determining
functionality is provided "As is" and "With all
faults". Sony Mobile Communications Inc.
does not make any representation or
warranty as to the accuracy of such location
information.
Use of location-based information by the
device may not be uninterrupted or error
free and may additionally be dependent on
network service availability. Please note that
functionality may be reduced or prevented
in certain environments such as building
interiors or areas adjacent to buildings.
Caution: Do not use GPS functionality in a
manner which causes distraction from
driving.
Emergency calls
Calls cannot be guaranteed under all
conditions. Never rely solely upon mobile
phones for essential communication. Calls
may not be possible in all areas, on all
networks, or when certain network services
and/or phone features are used.
Antenna
Use of antenna devices not marketed by
Sony Mobile Communications Inc. could
damage the phone, reduce performance,
and produce SAR levels above the
established limits. Do not cover the antenna
with your hand as this affects call quality,
power levels and can shorten talk and
standby times.
Radio Frequency (RF) exposure and
Specific Absorption Rate (SAR)
When the phone or Bluetooth handsfree is
turned on, it emits low levels of radio
frequency energy. International safety
guidelines have been developed through
periodic and thorough evaluation of
scientific studies. These guidelines establish
permitted levels of radio wave exposure.
The guidelines include a safety margin
designed to assure the safety of all persons
and to account for any variations in
measurements.
