238 Appendix
Safety precautions for Radio Frequency (RF) exposure
Use only original manufacturer-approved accessories, or accessories that do not
contain any metal
Use of non-original manufacturer-approved accessories may violate your local RF
exposure guidelines and should be avoided.
Exposure to RF Signals
Your device contains a radio transmitter and receiver. The radiated output power
is far below the international radio frequency exposure limits. These limits are part
of comprehensive guidelines and establish permitted levels of RF energy for the
general population. The guidelines are based on the safety standards previously set
by international standards bodies:
• American National Standards Institute (ANSI) IEEE. C95.1-1992
• National Council on Radiation Protection and Measurement (NCRP). Report
86. 1986
• International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1996
• Ministry of Health (Canada), Safety Code 6. The standards include a
substantial safety margin designed to assure the safety of all persons,
regardless of age and health.
The exposure standard for wireless mobile phones employs a unit of measurement
known as the Specific Absorption Rate, or SAR. The standard incorporates a
substantial margin of safety to give additional protection for the public and to
account for any variations in usage.
As with other mobile radio transmitting equipment, users are advised that for
satisfactory operation of the equipment and for the safety of personnel, it is
recommended that no part of the human body be allowed to come too close to the
antenna during operation of the equipment.
