89 Important information
Battery
We recommend that you fully charge the battery
before you use your mobile phone for the first time.
A new battery or one that has not been used for a
long time could have reduced capacity the first few
times it is used. The battery should only be charged
in temperatures between +5°C (+41°F) and +45°C
(+113°F).
Use only Sony Ericsson branded original batteries
intended for use with your mobile phone. Using
other batteries and chargers could be dangerous.
The talk and standby times depend on several
different conditions such as signal strength,
operating temperature, application usage patterns,
features selected and voice or data transmissions
when using the mobile phone.
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.
