RF Certification/Restrictions
80-99208-1 Rev. D B-3
RF Restrictions
The GSP-1620 modem must be used with the QUALCOMM-
provided antenna, and no modification to th e RF transmit or
receive path is permitted in the form of amplifiers.
QUALCOMM Incorporated must be consulted before any
changes can be made in the RF path, including cable leng th
deviations from the QUALCOMM-provided or recommended
cabling. Failure to do so may result in non-complian ce with
the Globalstar communications network and Government
Radio Regulations.

Radio Astronomy Zones

Radio Astronomy exclusion zones may be blacked out of
Globalstar service. The OEM manufacturer should consult
with the Globalstar Service Provider to ensure that service is
available in the location(s) of the installed OEM product.

GPS Interference Elimination

The modem antenna must be installed a minimum distance
of 30 inches from a GPS antenna to ensure compatibility
between the two satellite systems.
Radio Frequency Exposure Restrictions
The GSP-1620 modem incorporates a relatively low-power
radio transmitter, receiver, and antenna (the DRA). Wh en it
is ON it receives and sends radio frequency (RF) sign als. In
August 1996, the Federal Communications Co mmission
(FCC) adopted RF exposure g uidelines with safety levels for
portable wireless phones and devices. Those guideline s are
consistent with the safety stan dards previously set by both
US and international standards bodies:
• ANSI/IEEE C95.1-1992 Standard [American National
Standards Institute / Institute of Electrical and
Electronic Engineers]
• NCRP Report 86 (1986) [National Council on Radia tion
Protection and Measurements]
