71Important information

Personal medical devices

Phones may affect the operation of pacemakers

and other implanted equipment. Please avoid

placing the phone over the pacemaker, e.g. in

your breast pocket. When using the phone, use

it at the ear on the opposite side of the body to

the pacemaker. If a minimum distance of 15 cm

(6 inches) is kept between the phone and the

pacemaker, the risk of interference is limited. If

you have any reason to suspect that interference

is taking place, immediately turn off your phone.

Contact your cardiologist for more information.

For other medical devices, please consult your

physician and the manufacturer of the device.

Driving

Please check if local laws and regulations

restrict the use of mobile phones while driving

or require drivers to use hands-free solutions.

We recommend that you use only Sony Ericsson

hands-free solutions intended for use with your

product.

Please note that because of possible interference to

electronic equipment, some vehicle manufacturers

forbid the use of mobile phones in their vehicles

unless a hands-free kit with an external antenna has

been installed.

Always pay full attention to driving and pull off

the road and park before making or answering

a call if driving conditions so require.

Emergency calls

Mobile phones operate using radio signals, which

cannot guarantee connection in all conditions. You

should therefore never rely solely upon any mobile

phone for essential communications (e.g. medical

emergencies).

Emergency calls may not be possible in all areas,

on all cellular networks, or when certain network

services and/or mobile phone features are in use.

Check with your local service provider.

Antenna

This phone contains a built-in antenna. Use of

antenna devices not marketed by Sony Ericsson

specifically for this model could damage your

phone, reduce performance, and produce SAR

levels above the established limits (see below).

Efficient use

Hold your phone as you would any other phone.

Do not cover the top of the phone when it is in use,

as this affects call quality and may cause the phone

to operate at a higher power level than needed,

thus shortening talk and stand-by times.

Radio frequency (RF) exposure and

Specific Absorption Rate (SAR)

Your phone is a low-power radio transmitter and

receiver. When it is turned on, it emits low levels

of radio frequency energy (also known as radio

waves or radio frequency fields).

Governments around the world have adopted

comprehensive international safety guidelines,

developed by scientific organizations, e.g. ICNIRP

(International Commission on Non-Ionizing Radiation

Protection) and IEEE (The Institute of Electrical and

Electronics Engineers Inc.), through periodic and

thorough evaluation of scientific studies. These

guidelines establish permitted levels of radio wave

exposure for the general population. The levels

include a safety margin designed to assure the

safety of all persons, regardless of age and health,

and to account for any variations in measurements.

Specific Absorption Rate (SAR) is the unit of

measurement for the amount of 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

the actual SAR level of the mobile phone while it is

operating can be well below this value. This is

because the mobile phone is designed to use the

minimum power required to reach the network.
