Usage guidelines: All about performance and safety 137
In 1991-92, the Institute of Electrical and Electronics
Engineers (IEEE) and the American National Standards
Institute (ANSI) joined in updating ANSI’s 1982 standard for
safety levels with respect to human exposure to RF signals.
More than 120 scientists, engineers and physicians from
universities, government health agencies and industries
developed this updated standard after reviewing the available
body of research. In 1993, the Federal Communications
Commission (FCC) adopted this updated standard in a
regulation. In August 1996, the FCC adopted hybrid standard
consisting of the existing ANSI/IEEE standard and the
guidelines published by the National Council of Radiation
Protection and Measurements (NCRP).
Maintaining Your Phone’s Peak Performance
For the best care of your phone, only authorized personnel
should service your phone and accessories. Faulty service
may void the warranty.
There are several simple guidelines to operating your phone
properly and maintaining safe, satisfactory service.
• Hold the phone with the antenna raised, fully-extended
and over your shoulder.
• Try not to hold, bend or twist the phone’s antenna.
• Don’t use the phone if the antenna is damaged.
• Speak directly into the phone’s receiver.
• Avoid exposing your phone and accessories to rain or
liquid spills. If your phone does get wet, immediately turn
the power off and remove the battery. If it is inoperable,
return it to MetroPCS or call Customer Care for service.
