• Only use an antenna that has been specifically designed for your phone.

Unauthorised antennas, modifications, or attachments could damage the

phone and may violate the appropriate regulations causing loss of per-

formance and radio frequency (RF) energy above the recommended limits.

Efficient Phone Operation

A

To enjoy optimum performance with minimum power consumption please:

• Hold the phone as you would any other telephone. While speaking directly

s

into the mouthpiece, angle the antenna in a direction up and over your

shoulder. If the antenna is extendable/retractable,e

n

be extended

it should

during a call.

• Do not hold the antenna when the phone is in use. Holding the antenna

t

affects call quality, may cause the phone to operate at a higher power level

U

than needed and shorten talk and standby times. Ifa your mobile phone is

l

equipped with an infrared eye, never direct the infrared ray at anyone’s eye

and make sure that it does not disturb any

other infrared units.

Radio Frequency Energyc

Your mobile phone is a radior

transmitter andu

receiver. When the phone is

turned on, it receives and

transmits radio frequency (RF) energy. Depending

e

on the type of mobile phone you possess, it operates on different frequency

m

ranges and employs commonly used modulation techniques. The system that

m

handles your call when you are using your phone controls the power level at

which your phone transmits.

The International Commission on Non-Ionising Radiation Protection

(ICNIRP),C supported by the World Health Organisation (WHO), published

e

during1996 a statement and in 1998 guidelines which set recommended limits

r

l

for exposure to RFifields from handheld mobile telephones. According to

ICNIRPo

statement, which is based on the available body of research, there is

f

b

no evidence that mobile terminals meeting the recommended limits can cause

t

any adverse healtho

effects. All Ericsson telephones conform to the ICNIRP

guidelines and other international exposure standards, such as:

• CENELECM

European Pre-standard ENV50166-2:1995 (Europe)

• ANSI/IEEE C95.1-1992 (USA, Asia-Pacific)
