Chapter 1 – Introduction and Product
Description
Introduction
This User Guide describes the CallFinder ® Cellular Gateway: the CF100FX2-G; a GSM model with connectors
for both the FXS and FXO telephony interfaces.
The CallFinder cellular gateway connects to a PBX trunk line, a PBX extension line, or to a single PSTN (POTS)
line. It routes incoming and outgoing calls through the wireless network. Users can take advantage of the lower
costs that cellular networks offer under certain circumstances (like free calling between cellular phones from the
same provider, and free/reduced costs for weekend and night-time call s initiated on cellular phones). The
CallFinder can also be used to bring phone service to an area where land lines are not available or for
emergency access to the cellular network from a PBX.
Interfaces, Activation, & Configuration
The CF100FX2-G will connect to either an FXS or FXO interface; FXS is the default factory setting. The
CF100FX2-G is activated by inserting a SIM from a cellular provider; no AT commands are require d for this.
Configuration is done through Multi-Tech specific AT commands.

Safety Warnings
Handling Precautions
All devices must be handled with certain precautions to avoid damage due to the accumulation of static
charge. Although input protection circuitry has been incorporated into the devices to minimize the effect of
this static build up, proper precautions should be taken to avoid exposure to electrostatic discharge during
handling and mounting.
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.
Safety Recommendations for Rack Installations
• Ensure proper installation in a closed or multi-unit enclosure by following the recommended installation as
defined by the enclosure manufacturer.
• If installing the wireless CallFinder in a closed or multi-unit enclosure, ensure adequate airflow so that the
maximum recommended ambient temperature is not exceeded.
• Do not place the device directly on top of other equipment or place other equipment directly on top of this
device.
• Ensure that the device is properly connected to earth ground via a grounded power cord. If a power strip
is used, ensure that the power strip also provides adequate grounding.
• Ensure that the main supply circuit is capable of handling the load. See the power label on the device for
requirements.
• Maximum ambient temperature is 50 degrees Celsius.
• This device should be installed by qualified personnel.
• Only connect like circuits; e.g., connect SELV (Secondary Extra Low Voltage) circuits to SELV circuits and
TN (Telecommunications Network) circuits to TN circuits.
Safety Warnings Telecom
• Never install telephone wiring during a lightning storm.
• This product must be disconnected from power source and telephone network interface when servicing.
• This product is to be used with UL and cUL listed computers.
• Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at
the network interface.
• Use caution when installing or modifying telephone lines.
• Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote
risk of electrical shock from lightning.
• Do not use the telephone to report a gas leak in the vicinity of the leak.
• To reduce the risk of fire, use only 26 AWG or larger telecommunication line cord.
• Never install a telephone jack in wet locations unless the jack is specifically designed for wet locations.
• Do not connect the FXS port to an outside line (PSTN).
• Connect this product only to an indoor antenna.
• This product is not intended for use on a cable distribution system.

RF Interference Issues
It is important to follow any special regulations regarding the use of radio equipment due in particular to the
possibility of radio frequency, RF, interference. Please follow the safety advice given below carefully.
• Switch OFF your Wireless CallFinder when in an aircraft. The use of cellular telephones in an aircraft may
endanger the operation of the aircraft, disrupt the cellular network and is illegal. Failure to observe this
instruction may lead to suspension or denial of cellular telephone services to the offender, or legal action
or both.
• Switch OFF your Wireless CallFinder when around gasoline or dies el-fuel pumps and before filling your
vehicle with fuel.
• Switch OFF your Wireless CallFinder 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 where blasting
operations are in progress.
• There may be a hazard associated with the operation of your Wireless CallFinder close to inadequately
protected personal medical devices such as hearing aids and pace makers. Consult the manufacturers of
the medical device to determine if it is adequately protected.
• Operation of your Wireless CallFinder close to other electronic equipment may also cause interfere nce if
the equipment is inadequately protected. Observe any warning signs and manufacturers’
recommendations.
