8.3 Radio Frequency Exposure Restrictions
This section describes RF exposure safety issues related to using a GSP 1620
Modem, explains how to avoid excessive levels of RF exposure, and provides
language which should be incorporated into the End User documentation (User
Guide and Installation Manual), to satisfy FCC requirements.
8.3.1 Radio Frequency Energy
The GSP 1620 Modem incorporates a relatively low-power radio transmitter,
receiver, and antenna (the ODU). When it is ON it receives and also sends out
radio frequency (RF) signals. In August 1996, the Federal Communications
Commission (FCC) adopted RF exposure guidelines with safety levels for
portable wireless phones and devices. Those guidelines are consistent with the
safety standards previously set by both US and international standards bodies:
ANSI/IEEE C95.1-1992 Standard
1
NCRP Report 86 (1986)
2
ICNIRP (1996)
3
IRPA (1991)
4
The modem is designed to comply with the established ANSI, FCC, and
international safety standards for safe levels of human exposure to RF energy.
Nonetheless, RF field intensity at the surface of the transmitting Globalstar
antenna is fairly high. Maintaining a minimum line-of-sight separation distance of
21.5 cm (8.5 inches) between the transmitting antenna and all personnel will
ensure that the General Population / Uncontrolled Exposure maximum
permissible exposure (MPE) limits are not exceeded. This satisfies the MPE
limits mandated by the FCC in 47 CFR Ch. 1 (10-1-99 Edition), Part 1, §1.1310
and defined in the ANSI/IEEE C95.1-1992 standard, and also satisfies the
slightly more-stringent European and international exposure limit
recommendations of IRPA (1991) and ICNIRP (1996).
