Guidelines for Safe and Efficient Use
Important: Read this information before using your portable phone
General
Since its introduction in the mid 1980s the portable phone is one of the most exciting and innovative products ever developed. With it, you
can stay in contact with your office, your home,
emergency services, and others.
Your telephone is a radio tran smitter and receiver. When it is ON it receives and also sends
out radio frequency (RF) energy. Depending
upon the type of m ob i l e pho ne you have purchased, it operates in different frequency ranges
and employs commonly used modulation techniques. When yo u us e yo ur ph one, the system
handling yo ur c all control s the power level at
which your phone transmit s .
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), published a statement in 1996 which sets limits for exposure to RF fields from handheld mobile
Not for Commercial Use
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 international 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 operate your phone in the most power
efficient manner.
Efficient phone operation
How to use your phone for optimum perfor m ance with minimum power consumption:
Hold the phone as you would any ot her telephone. While speaking directly into the mouthpiece, 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 time s .
Antenna care and replacement
Do not use the phone with a damaged antenna.
Replace a damaged antenna immediately. Consult your manua l to see if you may chan ge the
antenna yourself. If so, use only an Ericsson approved antenna. Other w ise, take your phone to a
qualified service centre for repair.
Use only the designated Ericsson ant e nna. Unauthorized antennas, modifications, or attachments could damage the phone and may violate
the appropriate regulations.
Do not use an antenna designed for any other
type of portable te l e ph on e t han 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 , w hen 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 answering a call if driving condit io ns so requ ire .
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 manufacturer’s representative to be sure your phone
will not affect the electronic systems of your vehicle.
Electronic devices
Most modern electronic equipment, for example, equipment in hospitals and cars, is shielded
from RF energy. However, RF energy from telephones may affect some electronic equipment.
Turn your phone OFF in health care facilities
when regulations posted in the areas instruct
you to do so. Alwa ys re quest permiss io n be f o r e
using your phone near medical equipment.
Mobile telephones may affect the operation of
some implanted cardiac pacemakers, equipment
for people with hearing impai rments and other
medically implanted equipment. Pacemaker patients 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 opposite the pacemaker. If a distance of 15cm. is
kept between the phone and the pacemaker, the
Not for Commercial Use
risk of interference is limited. Contact your cardiologist for more information.
Aircraft
Turn your phone OF F be f o r e boa rding any aircraft.
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 prevent interference with communication systems,
you must not use your phone while the plane is
in the air.
Power Sup ply
Connect AC (Power supply) only to designated
power sources as marked on the product.
To reduce risk of damage to electric cord, remove from outlet by holding onto AC adapter
rather than cord.
Make sure the cord is located so that it will not
be stepped on, t ripped over or other wise subjected to damage or stress.
To reduce risk of electric shock, unplug unit
from power source before attempting any cleaning, then use soft cloth dampened on with water.
Children
Do not allow children to play with yo ur 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”. Construction crews often use remote control RF devices 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 explosion 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 gas stations, below deck on boats, fuel or chemical transfer or
storage facilities, and areas where the air contains chemicals or particles, such as grain, dust,
or metal powders.
ii

and the SIM Card
The Battery
Your phone is supplied with a Nickel Metal Hydride battery. The battery is not charged before
shipment, even though there might be enough
power to turn the phone on.
The SIM Card
Before you can start usin g your phone, you
need to order a SIM Card from a GSM service
provider. The SIM Card keeps track of your
phone number, the services that you order from
the service provider and your phone book information.
Your SIM Card is supplied with a security code
or PIN (Personal Identity Number). You must
enter this into the phone to gain access to the
phone and network.
Note!
Some services de sc r i be d i n th is m a nu a l m a y no t
be avialable in all networks. Please, see you
service provider for more information.
