Notices

Safety. Exposure to RF energy is an important safety consideration. The FCC has adopted a
safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC
regulated equipment as a result of its actions in General Docket 79-144 on March 13, 1986.
Proper use of th is radio modem res ults in exposure bel ow government limits. The following
precautions are recommended:

DO NOT operate the transmitter when someone is within two feet (0.6 meter) of the antenna.
DO NOT operate the transmitter unless all RF connectors are secure and any open connectors

are properly terminated.
DO NOT operate the equipment near electrical blasting caps or in an explosive atmosphere.
All equipment must be properly grounded according to Trimble installation instructions for

safe operation.
All equipment should be serviced only by a qualified technician.
Class A Computing Device—Information to User. This equipment has been tested and

found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment gen erates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user
will be required to correct the interference at his own expense.
