radio-modem frequency bands. To comply with those requirements, Spectra Precision
may have modified your equipment to be granted Type approval. Unauthorized
modification of the units voids the Type approval, the warranty, and the operational
license of the equipment.

Exposure to radio frequency radiation
24.1
For UHF radio
For example, a 450 MHz radio.
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.
Proper use of this radio modem results in exposure below government limits. The
following precautions are recommended:
•
DO NOT
operate the transmitter when someone is within 20 cm (7.8 inches) of
the antenna.
•
DO NOT
collocate (place within 20 cm) the radio antenna with any other
transmitting device.
•
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 Spectra Precision
installation instructions for safe operation.
•
All equipment should be serviced only by a qualified technician.
24.2
For Bluetooth radio
The radiated output power of the internal Bluetooth wireless radio is far below the
FCC radio frequency exposure limits. Nevertheless, the wireless radio shall be used in
such a manner that the Spectra Precision receiver is 20 cm or further from the human
body. The internal wireless radio operates within guidelines found in radio frequency
safety standards and recommendations, which reflect the consensus of the scientific
community. Spectra Precision therefore believes the internal wireless radio is safe for
use by consumers. The level of energy emitted is far less than the electromagnetic
energy emitted by wireless devices such as mobile phones. However, the use of wireless
radios may be restricted in some situations or environments, such as on aircraft. If you
are unsure of restrictions, you are encouraged to ask for authorization before turning
on the wireless radio.
