Guidelines for safe and efficient use 87

Turn off your mobile phone before removing the
battery. Do not allow the battery to be put into the
mouth. Battery electrolytes may be toxic if
swallowed. Do not let the metal contacts on the
battery touch another metal object. This could short-
circuit and damage the battery. Use the battery for the
intended purpose only.
Personal medical devices
Mobile phones may affect the operation of cardiac
pacemakers and other implanted equipment. Please
avoid placing the mobile phone over the pacemaker,
e.g. in your breast pocket. When using the mobile
phone, place it at the ear opposite the pacemaker. If a
minimum distance of 15 cm (6 inches) is kept
between the mobile 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 mobile 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 handsfree solutions. We recommend that you
use only Sony Ericsson handsfree 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 handsfree kit with an external antenna
supports the installation.
Always give 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 under all conditions.
Therefore you should 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 mobile
phone, reduce performance, and produce SAR levels
above the established limits (see below).
Efficient use
Hold your mobile phone as you would any other
phone. Do not cover the top of the phone when 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 standby times.
Radio frequency (RF) exposure
and SAR
Your mobile 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
