Introduction
This guide shows you how to set up your Multi-Tech wireless
MultiModem. For detailed information, product specifications,
troubleshooting tips, and more, see the User Guide, available on the
MultiModem CD accompanying your wireless modem.
General Safety
The modem is designed for and intended to be used in fixed and
mobile applications. “Fixed” means that the device is physically
secured at one location and is not able to be easily moved to
another location. In a “Mobile” application, the device may be moved
regularly from one location to another.
Caution: Maintain a separation distance of at least 20 cm (8 inches)
between the transmitter’s antenna and the body of the user or
nearby persons. The modem is not designed for, nor intended to be,
used in applications within 20 cm (8 inches) of the body of the user.
RF Interference Issues
Avoid possible radio frequency (RF) interference by carefully
following the safety guidelines below.
•Switch OFF the MultiModem when in an aircraft. The use of
cellular telephones in aircraft is illegal. It may endanger the
operation of the aircraft and/or disrupt the cellular network.
Failure to observe this instruction may lead to suspension or
denial of cellular services to the offender, legal action, or both.
•Switch OFF the MultiModem in the vicinity of gasoline or diesel-
fuel pumps or before filling a vehicle with fuel.
•Switch OFF the MultiModem in hospitals and any other place
where medical equipment may be in use.
•Respect restrictions on the use of radio equipment in fuel
depots, chemical plants, or in areas of blasting operations.
•There may be a hazard associated with the operation of your
MultiModem in the vicinity of inadequately protected personal
medical devices such as hearing aids and pacemakers.
Consult the manufacturers of the medical device to determine if
it is adequately protected.
