Emergency calls
Calls cannot be guaranteed under all conditions. Never rely solely upon mobile phones for
essential communications. 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 Ericsson could damage your 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 your 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 mobile 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 below this value. There is no proof of difference in safety based on difference in SAR
value.
Products with radio transmitters sold in the US must be certified by the Federal
Communications Commission (FCC). When required, tests are performed when the
phone is placed at the ear and when worn on the body. For body-worn operation, the
phone has been tested when positioned a minimum of 15 mm from the body without any
metal parts in the vicinity of the phone or when properly used with an appropriate
Sony Ericsson accessory and worn on the body.

Malware
Malware (short for malicious software) is software that can harm your mobile phone or
other computers. Malware or harmful applications can include viruses, worms, spyware,
and other unwanted programs. While your device does employ security measures to
resist such efforts, Sony Ericsson does not warrant or represent that your device will be
impervious to introduction of malware. You can however reduce the risk of malware
attacks by using care when downloading content or accepting applications, refraining
from opening or responding to messages from unknown sources, using trustworthy
services to access the Internet, and only downloading content to your mobile phone from
known, reliable sources.
Accessories
Use only Sony Ericsson branded original accessories and certified service partners.
Sony Ericsson does not test third-party accessories. Accessories may influence RF
Exposure, radio performance, sound loudness, electric safety and other areas. Third-
party accessories and parts may pose a risk to your health or safety or decrease
performance.
