Please consult your network operator for
more information about your subscription.

operator, you get a SIM (Subscriber Identity
Module) card. The SIM card contains a computer
chip that keeps track of your phone number, the
services included in your subscription, and your
Phonebook information, among other things.

Note: Make sure that your information is saved to
the SIM card before you remove it from another
phone. For example, Phonebook entries may have
been saved in the phone memory and not the SIM. To
copy phonebook entries from phonebook to SIM, see
page see “Copy names and numbers” on page 31.

Code memo

Instead of having to remember all the different
security codes (for credit cards, etc.) you can save
them in the code memo in your phone. Then all you
need to remember is the password to open the code
memo. You can save a maximum of ten codes in the
code memo.

Checkword and security

To confirm that you have entered the correct
password for the code memo and to prevent
unauthorized access to your codes, you must enter a
checkword. When you enter your password to open

time. If the passwo rd i s co rrec t, th e corr ect cod es are
shown. If you enter the incorrect password,
the checkword and the codes that are shown are
also incorrect.
Factors strengthening the security of the Code memo
function are:

• You get no feedback about whether the password is
correct, except for the checkword, and only you
know the checkword.

• All codes are encrypted in the mobile phone.

• When you access your codes, they are shown for a
limited time only.

To open code memo for the firs t time

Guidelines for Safe and Efficient Use

Please read this information before using

your mobile phone.

RECOMMENDATIONS

• Always treat your product with care and keep it in a
clean a nd dust-free place.

• Do not expose your p ro duct to liqu id or moistur e
or humidity.

• Do not expo se your pro duct to extreme
high or l ow temperat ures.

• Do not expo se your pro duct to open
flames or lit tobacco products.

• Do not drop, throw or try to bend
your product.

• Do not paint your product.

86 Additional information

• Do not use your product near medical equipment
without r equestin g permissio n.

• Do not use your product when in, or around aircraft,
or areas posted “turn off two-way radio”.

• Do not use your produc t in an area wher e
a potentially explo sive atmosphe r e exists.

• Do not place your product or install
wireless equipment in the area above
your car’s air bag.

• Do not attempt to disassemble your
product. Only Sony Ericsson authorized
personnel should perfor m ser v i ce.

ANTENNA

Only use an antenna that has been spe ci fically
designed by S ony Eri cs son f or you r mob il e ph one. U se
of unauthorized or modified antennas could damage
your mobile phone and may violate regulations,
causing l oss o f pe rf or mance a nd S AR lev el s abo ve the
recommended limits (see below).

EFFICIENT USE

Hold your m obile phone as you w ould any other
phone. Do not cover the top of the pho ne when in use,

T637UG.book Page 87 Friday, January 9, 2004 10:46 AM

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 emi t s low level s o f
radio fre quency energy ( also known as r adio waves or
radio frequency fields).
Govern m ents aroun d the world have adopt ed
comprehensive international safety guidelines,
developed by scientific organizations, e.g. ICNIRP
(Intern at ional Commissio n on Non-Ionizing Radiation
Protection) and IEEE (The Institute of Electrical and
Electronics Engineers Inc .), t hr ough peri odic 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 pe r sons, regar dless of a ge 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 us in g a mobile
phone. The SAR v al ue is determined at t he highest
certified power level in laboratory conditions, but the
actual SAR level of the mobile phone while 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.
Variations in SAR below the radio frequency exposure
guidelin es do not m ean that there are var iations in
safety. While th er e may be di ffer ences in SA R levels
among mobile phones, all Sony Ericsson mobile
phone models are designed to meet radio frequency
exposure guidelines.

Before a phone model is available for sale to the
public, i t m ust be tested and certified to t he FCC that it
does not exceed the limit established by the
government-adopted requirement for safe exposure.
The tests a re performed in positio ns and locat ions
(that is, at the ear and worn on the body) as required
by the FCC for each model. For body worn operation,
this phone has been tested and meets FCC RF
exposure guidelines when the handset is positioned a
minimum of 20 mm f r om the body w ithout any metal
parts in the vicinity of the phone or when used with the
original Sony Ericsson body worn accessory intended
for this phone. Use of other accessories may not
ensure compliance with FCC RF exposure guidelines.
A separate leaflet with SAR information for this mobile
phone model is included with the material that comes
with this mobile phone. This information can also be
found, together with more information on radio
frequenc y exposure and SAR, on:
www.sonyericsson.com.

DRIVING

Please ch eck if local laws and regu la t io ns restrict the
use of mobile phon es whi le dr i ving or re quir e dri ve rs to
use handsfree solutions. We recommend that you use
only Ericss on or Sony Ericss on handsfree sol ut ions
intended for use with your product. Please note that
because of possible interference to electronic
equipment, some vehic l e manufacturers for bid the us e
of mobile phones in their vehicles unless a handsfree
kit with an external antenna supports the installation.

Always giv e ful l at t ent ion t o dr i ving a nd pull of f t he r oad
and park before ma king or ans wering a call if driving
conditions so require.

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 othe r m edical de vi c es, please consult the
manufacturer of the device.

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 f or es sential communications
(e.g. medical emergencies).
Emergency calls may not be possible on all cellular
networks or when certain network services and/or
mobile phone f ea t ur es are in use. Check w i th your
local service provider.

A new batter y or one tha t has not been used for a long
time could have reduced capacity the first few times it
is used.
The talk and standby times depend on the actual
transmission conditions when using the mo bi le phone.
If the mobile phone is used near a base station, less
power is required and talk and standby times are
prolonged.

• Warnin g! May explode if disposed of in fire.

• Use only Ericsson or Sony Ericsson branded original
batteries and cha r gers intended for u se with you r
mobile phone. Other chargers may not charge
sufficiently or may produce excessive heat. Using
other batteries and chargers could be dangerous.

• Do not expose the battery to liquid.

• Do not let the metal contacts on the battery touch
another metal object. This could short-circuit and
damage the battery.

• Do not disassemble or modify the battery.

• Do not expose the battery to extreme
temperatures, never above +60°C
(+140°F). For maximum battery capacity,
use the battery in room temperature.
