Safety precautions for 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 Radio Frequency (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.
Your device has an internal antenna. Use only the supplied integral antenna.
Use of unauthorized or modified antennas may impair call quality and
damage the phone, causing loss of performance and SAR levels exceeding
the recommended limits as well as result in non-compliance with local
regulatory requirements in your country.
To assure optimal phone performance and ensure human exposure to RF
energy is within the guidelines set forth in the relevant standards; always
