Exposure to Radio Frequency Signal
Your wireless handheld portable telephone is a lowpower radio transmitter and
receiver. When it is ON, it receives and also sends out radio frequency (RF) signals.
In August, 1996, the Federal Communications Commissions (FCC) adopted
RF exposure guidelines with safety levels for handheld wireless phones. Those
guidelines are consistent with the safety standards previously set by both U.S. and
international standards bodies:
ANSI C95.1 (1992) *
NCRP Report 86 (1986)
ICNIRP (1996)
Those standards were based on comprehensive and periodic evaluations of the
relevant scientific literature. For example, over 120 scientists, engineers, and
physicians from universities, government health agencies, and industry reviewed
the available body of research to develop the ANSI Standard (C95.1).
* American National Standards Institute; National Council on Radiation Protection
and Measurements; International Commission on Non-Ionizing Radiation
Protection.
The design of your phone complies with the FCC guidelines (and those standards).

NORMAL POSITION: Hold the phone as you would any other telephone with the
antenna pointed up and over your shoulder.

12Safety instructions
Suggestions for a more efficient operation
For your phone to operate most efficiently:
• Do not touch the antenna unnecessarily, when the phone is in use. The contact
with the antenna affects call quality, and may cause the phone to operate at a
higher power level than otherwise would be need.
Driving
Check the laws and regulations related to the use of wireless phones in the areas
where you drive. Always obey these regulations. Also, if using your phone while
driving, make sure to:
• Pay full attention to driving; driving safely is your first responsibility;
• Use hands-free operation, if available;
• Pull off the road and park, before making or answering a call, if driving
conditions demand so.
Electronic Devices
Most modern electronic equipment is shielded from RF signals.
However, certain electronic equipment may not be shielded against the RF signals
from your wireless phone.
Pacemaker
The Medical Industry Manufacturers Association recommends a minimum distance
of fifteen (15) centimeters, or six (6) inches, between a handheld wireless phone
and a pacemaker, in order to avoid potential interference between them.
These advices are consistent with independent researches, and with
recommendations based on wireless technology research.
People with pacemakers should:
• ALWAYS keep the phone at least fifteen centimeters (six inches) from their
pacemaker, whenever the phone is turned on;
• Not carry the phone in a shirt pocket;
• Use the ear opposite to the pacemaker, to minimize the potential interference;
• If you have any reason to suspect that interference is taking place, switch off
your phone immediately.

13Safety instructions
Hearing Aids
Some digital wireless phones may interfere with some hearing aids. In the event of
such interference, we recommend that you contact your service provider.
Other Medical Devices
If you use any other personal medical devices, consult your device manufacturer to
determine if they are adequately shielded from external RF energy. Your doctor can
help you obtain this information.
