Guidelines for Safe and Efficient Use
Important: Read this information before using your portable phone.
General
Since its introduction in the mid 1980s the port-
able phone is one of the most exciting and inno-
vative products ever developed. With it, you
can stay in contact with your office, your home,
emergency services, and others.
Your telephone is a radio transmitter and re-
ceiver. When it is ON it receives and also sends
out radio frequency (RF) energy. Depending
upon the type of mobile phone you have pur-
chased, it operates in different frequency ranges
and employs commonly used modulation tech-
niques. When you use your phone, the system
handling your call controls the power level at
which your phone transmits.
For the safe and efficient
operation of your phone,
observe these guidelines
Exposure to radio frequency
energy
The International Commission on Non-Ionizing
Radiation Protection (ICNIRP), sponsored by
the World Health Organization (WHO), publish-
ed a statement in 1996 which sets limits for ex-
posure to RF fields from handheld mobile
phone. According to this statement, which is
based on the available body of research, there is
no evidence that mobile terminals meeting the
recommended limits can cause any adverse
health effects. All Ericsson telephones conform
to the ICNIRP recommendations, and interna-
tional exposure standards, such as:
CENELEC European Pre-standard
ENV50166-2
ANSI/IEEE C95.1-1992 (USA, Asia- Pacific)
If you want to limit RF exposure even further,
you may choose to control the duration of your
calls and operateyour phone in the most power
efficient manner.
Efficient phone operation
How to use your phone for optimum perform-
ance with minimum power consumption:
Hold the phone as you would any other tele-
phone. While speaking directly into the mouth-
piece, angle the antenna in a direction up and
over your shoulder. If the antenna is extendable,
it should be extended during a call.
Do not hold the antenna when the phone is IN
USE. Holding the antenna affects call quality,
may cause the phone to operate at a higher
power level than needed and shorten talk and
standby times.
Antenna care and replacement
Do not use the phone with a damaged antenna.
Replace a damaged antenna immediately. Con-
sult your manual to see if you may change the
antenna yourself. If so, use only an Ericsson ap-
proved antenna. Otherwise, take your phone to
a qualified service centre for repair.
Use only the designated Ericsson antenna. Un-
authorized antennas, modifications, or attach-
ments could damage the phone and may violate
the appropriate regulations.
Do not use an antenna designed for any other
type of portable telephone than the telephone
you have purchased.
Driving
Check the laws and regulations on the use of
telephones in the areas where you drive. Always
obey them. Also, when using your phone while
driving, please:
Give full attention to driving.
Use hands-free operation, if available.
Pull off the road and park before making or an-
swering a call if driving conditions so require.
ii EN/LZT 126 1353 R1A
RF energy may affect some electronic systems
in motor vehicles. In addition, some vehicle
manufacturers forbid the use of mobile phones
in their vehicles. Check with your vehicle manu-
facturer’s representative to be sure your phone
will not affect the electronic systems of your ve-
hicle.
Electronic devices
Most modern electronic equipment, for exam-
ple, equipment in hospitals and cars, is shielded
from RF energy. However, RF energy from tele-
phones may affect some electronic equipment.
Turn your phone OFF in health care facilities
when regulations posted in the areas instruct
you to do so. Always request permission before
using your phone near medical equipment.
Mobile telephones may affect the operation of
some implanted cardiac pacemakers, equipment
for people with hearing impairments and other
medically implanted equipment. Pacemaker pa-
tients should be aware that the use of a mobile
phone very close to a pacemaker may cause the
device to malfunction. Avoid placing the phone
over the pacemaker, i.e. in your breast pocket.
When using the phone, place it at your ear oppo-
site the pacemaker. If a distance of 15cm. is
kept between the phone and the pacemaker, the
risk of interference is limited. Contact your car-
diologist for more information.
Aircraft
Turn your phone OFF before boarding any air-
craft.
Use it on the ground only with crew permission
Turn off your phone before the aircraft leaves
the ground. Do not use it in the air.
To prevent possible interference with aircraft
systems, safety regulations require you to have
permission from a crew member to use your
phone while the plane is on the ground. To pre-
vent interference with communication systems,
you must not use your phone while the plane is
in the air.
Power Supply
Connect AC (Power supply) only to designated
power sources as marked on the product.
To reduce risk of damage to electric cord, re-
move from outlet by holding onto AC adapter
rather than cord.
Make sure the cord is located so that it will not
be stepped on, tripped over or otherwise sub-
jected to damage or stress.
To reduce risk of electric shock, unplug unit
from power source before attempting any clean-
ing, then use soft cloth dampened on with water.
Children
Do not allow children to play with your phone.
It is not a toy. Children could hurt themselves
or others (by poking themselves or others in the
eye with the antenna for example). Children
could also damage the phone or make calls that
increase your telephone bills.
Blasting areas
To avoid interfering with blasting operations,
turn your unit OFF when in a “blasting area” or
in areas posted “turn off two-way radio”. Con-
struction crews often use remote control RF de-
vices to set off explosives.
Potentially explosive atmospheres
Turn your phone OFF when in any area with a
potentially explosive atmosphere. It is rare, but
your phone or its accessories could generate
sparks. Sparks in such areas could cause an ex-
plosion or fire resulting in bodily injury or even
death.
Areas with a potentially explosive atmosphere
are often, but not always, clearly marked. They
include fuelling areas, such as petrol stations,
below deck on boats, fuel or chemical transfer
or storage facilities, and areas where the air con-
tains chemicals or particles, such as grain, dust,
or metal powders.
Do not transport or store flammable gas, liquid,
or explosives in the compartment of your vehi-
cle which contains your phone and accessories.
Product care
Do Not expose product to water or moisture.
EN/LZT 126 1353 R1A iii
Example: bathtub, laundry sink, wet/damp base-
ment, swimming pools, etc.
Do Not expose product to extreme tempera-
tures such as found near a hot radiator or stove,
or in a car parked in the sun.
Do not expose product to extreme cold tem-
peratures such as a car parked outdoors in win-
ter.
Do Not expose product to lit candles, ciga-
rettes, cigars, open flames, etc.
Use only Ericsson Original accessories. Fail-
ure to do so may result in loss of performance,
fire, electric shock, or injury, and will void the
warranty.
Do Not attempt to disassemble the product. Do-
ing so will void warranty. This product does
not contain consumer serviceable components.
Service should only be performed by Author-
ized Service Centres.

2. Making the Phone Ready for Use
This chapter describes how you assemble the phone, what the SIM Card is, and how
you handle the battery.
To insert the SIM card
When you become a subscriber of a network op-
erator, you obtain a SIM card with a personal se-
curity code, the PIN code. The SIM card
contains a computer chip that keeps track of
your phone number, the services that you have
ordered from your network operator, and your
phone book information.
Before you can use the phone, you must insert
the SIM card into the phone.
1. Release the card holder by sliding it from you.
2. Unfold the holder.
3. Slide the mini SIM card into the holder.
Make certain that the angled corner is top
right.
4. Fold down the card holder.
5. Lock the card holder by sliding it towards you.

About the battery
Your phone is supplied with a Nickel Metal Hy-
dride battery. The battery is not charged before
shipment, even though there might be enough
power to turn the phone on.
Low Battery Alarm
As a reminder that the battery soon needs re-
charging or replacing, an alarm signal (a long
beep) sounds and the message ‘Battery low’ ap-
pears for ten seconds in the display.
In addition, the indicator light on the top of the
phone starts blinking red. If the phone is left
on, the low battery alarm will be repeated sev-
eral times and, finally, the phone will turn itself
off when the battery is no longer able to power
it satisfactorily. It is not possible to turn the
phone on again. Instead the battery must be re-
charged, or replaced with a charged one.
3. Turning the Phone On
This chapter describes how to turn the phone on and off, how to choose another
language than English in the display, if this is desired, and how to set the phone’s
clock.
To turn the phone on
1. Press and hold down the NO (ON/OFF) key until
you hear a click. The display will prompt you
to enter your PIN (the security code that fol-
lows your SIM Card).
