signal strength, usage patterns, features selected
and voice or data transmissions. Only
Sony Ericsson service partners should remove or
replace built-in batteries. Use of batteries that are
not Sony Ericsson branded may pose increased
safety risks. Replace the battery only with another
Sony Ericsson battery that has been qualified with
the product per the standard IEEE-1725. Use of an
unqualified battery may present a risk of fire,
explosion, leakage or other hazard.
Personal medical devices
Phones may affect implanted medical equipment.
Reduce risk of interference by keeping a minimum
distance of 6 inches (15 cm) between the phone and
the device. Use the phone at your right ear. Do not
carry the phone in your breast pocket. Turn off the
phone if you suspect interference. For all medical
devices, consult a physician and the manufacturer.
Some vehicle manufacturers forbid the use of
phones in their vehicles unless a handsfree kit with
an external antenna supports the installation. Check
with the vehicle manufacturer's representative to be
sure that the phone or Bluetooth handsfree will not
affect the electronic systems in the vehicle. Full
attention should be given to driving at all times and
local laws and regulations restricting the use of
wireless devices while driving must be observed.
GPS/Location based functions
Some products provide GPS/Location based
functions. Location determining functionality is
provided “As is” and “With all faults”.
Sony Ericsson does not make any representation or
warranty as to the accuracy of such location
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 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.
Use of antenna devices not marketed by
Sony Ericsson 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.
Specific Absorption Rate (SAR) is used to measure
radio frequency energy absorbed by the body when
using a phone. The SAR value is determined at the
highest certified power level in laboratory
conditions, but because the phone is designed to
use the minimum power necessary to access the
chosen network, the actual SAR level can be well
