Introduction
The CallFinder Cellular Gateway connects to a PBX trunk line, PBX
extension line, or to a single PSTN (POTS) line and routes incoming and
outgoing calls through the wireless network. This Quick Start Guide will
detail the physical connections needed for the CallFinder as well as a
few basic setup examples and usage precautions.
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.

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
diesel-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 pacemakers. 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 interference if the equipment is
inadequately protected. Observe any warning signs and
manufacturers’ recommendations.

General Setup
Prerequisites:
•You must have the SIM chip from your wireless service provider.
•A small, needle-nose pliers is helpful for inserting the SIM into
its receptacle.
1. Remove the CF100 CallFinder unit from its shipping box.
2. Use a small Phillips screwdriver to remove the SIM cover screw that is
closest to the edge of the chassis. Loosen the second SIM screw
slightly, rotate the cover 180 degrees, and then re-tighten the second
SIM screw slightly to keep the SIM compartment open.
3. Orient the SIM to match the marking in the SIM compartment (the
notched part of the SIM should be near the outer edge of the
CallFinder unit). Insert the SIM into its receptacle (a small needle-
nosed pliers can be helpful for this). Loosen the SIM cover screw
slightly, rotate the SIM cover 180 degrees to its closed position, and
tighten both SIM cover screws.
4. Attach the antenna to the CallFinder.
5. Be sure that the “VOICE/DATA” switch is in the VOICE position.
6. Connect power to the CallFinder.
7. Connect the RJ-11 cable to the appropriate receptacle on the rear of
the CallFinder.
