Modem Use
The 819-GPRS modem is designed and intended for use in fixed and mobile applications.
“Fixed” assumes the device is physically secured at one location and not easily moved to
another location. Please keep the cellular antenna of the 819-GPRS at a safe distance from
your head and body while the modem is in use (see below).
Important
Maintain a distance of at least 20 cm (8 inches) between the transmitter’s antenna and any
person while in use. This modem is designed for use in applications that observe the 20 cm
separation distance.
Interference Issues
Avoid possible radio frequency (RF) interference by following these guidelines:
•
The use of cellular telephones or devices in aircraft is illegal. Use in aircraft may
endanger operation and disrupt the cellular network. Failure to observe this
restriction may result in suspension or denial of cellular services to the offender,
legal action or both.
•
Do not operate in the vicinity of gasoline or diesel-fuel pumps unless use has been
approved and authorized.
•
Do not operate in locations where medical equipment that the device could interfere
with may be in use.
•
Do not operate in fuel depots, chemical plants, or blasting areas unless use has been
approved and authorized.
•
Use care if operating in the vicinity of protected personal medical devices, i.e.,
hearing aids and pacemakers.
•
Operation in the presence of other electronic equipment may cause interference if
equipment is incorrectly protected. Follow recommendations for installation from
equipment manufacturers.
