SX4e GSM 1900 4USER MANUAL
Safety Information
Your Phonecell SX4e FWT (Fixed Wireless Terminal) functions as both a
radio transmitter and receiver. When it is ON, the FWTreceives and sends out
radio frequency (RF) energy. The SX4e GSM 1900 operates between 1850
MHz and 1990 MHz. It employs the commonly used phase/frequency modu-
lation techniques. When you use your Phonecell SX4e, the cellular system
handling your call controls the power level at which your unit transmits.
Nominal power for the GSM 1900 unit is 1 watt.
Exposure to RF (Radio Frequency) Energy
In 1991, the Institute of Electrical and Electronics Engineers (IEEE), and in 1992, the
American National Standards Institute (ANSI), updated the 1982 ANSI Standard for
safety levels with respect to human exposure to RF energy. After reviewing the
available body of research, more than 120 scientists, engineers and physicians from
universities, government health agencies and industry developed this updated
Standard. In March, 1993, the U.S. Federal Communications Commission (FCC)
proposed the adoption of this updated Standard.
The design of your Telular Phonecell SX4e FWT (Fixed Wireless Terminal) complies
with the requirements of EN 55022, 47 CFR Part 15, Class B, and ICES-003 for con-
ducted and radiated emissions. Of course, if you want to limit RF exposure even fur-
ther than the updated ANSI Standard, you may choose to control the duration of your
calls and operate your phone in the most power-efficient manner.
Safe Operation Requirement
Do not operate your Phonecell when any person is within 8 inches (20 cm) of the antenna.
Protective Earth (Safety Ground) Terminal
A protective earth (safety ground) terminal (screw) marked with the
protective earth symbol is provided on the back of the SX4 Phonecell unit.
This terminal must have a permanent connection to a good earth ground
(i.e. a cold water pipe) by means of an 18 gauge or heavier insulated wire.
The wire insulation should be green with a yellow stripe to indicate that this is a
protective earth (safety ground) connection.
WARNING: The protective earth is to be installed by a qualified electrician.
Temperature Environment
Operating Temperature:: From -10°C (14°F) to +50°C (122°F);
Up to 95% relative humidity (non-condensing)
Storage Temperature: From -20°C (-4°F) to +60°C (140°F);
Up to 95% relative humidity (non-condensing)
WARNING!
Your Phonecell must be placed or mounted on a flat surface to allow proper
ventilation.Donot blocktheairvents orthespacebeneathyour Phonecellas
this could cause the unit to overheat and fail.
!
IMPORTANT!
To ensure safe and efficient operation, please read the following information
and observe these guidelines whenever using your Phonecell FWT.

SX4e GSM 1900 5USER MANUAL
Safety Information - continued
Driving Check the laws and regulations on the use of cellular products
in the areas where you drive. Some jurisdictions prohibit your
using a cellular device while driving a vehicle. Even if your
jurisdiction does not have such a law, we strongly suggest that,
for safety reasons, the driver use extreme caution when operating the cellular
device while the vehicle is in motion. Always obey the law.
Electronic Devices
Most modern electronic equipment is shielded from RF energy. However, RF
energy from cellular devices may affect inadequately shielded electronic
equipment.
RF energy may affect improperly installed or inadequately shielded electronic
operating and entertainment systems in motor vehicles. Check with the
manufacturer or its representative to determine if these systems are adequately
shielded from external RF energy. You should also check with the manufacturer of
any equipment that has been added to your vehicle.
Consult the manufacturer of any personal medical devices (such as pacemakers,
hearing aids, etc.) to determine if they are adequately shielded from external RF
energy.
Turn your Phonecell FWT OFF in health care facilities when any regulations
posted in the areas instruct you to do so. Hospitals or health care facilities may be
using equipment that could be sensitive to external RF energy.
Aircraft
Turn OFF your Phonecell before boarding any aircraft.
•• Use it on the ground only with crew permission.
•• Do not use it in the air.
To prevent possible interference with aircraft systems, U.S.
Federal Aviation Administration (FAA) regulations require you to have permission
from a crew member to use your cellular phone (or any other cellular product)
while the plane is on the ground. To prevent interference with aircraft systems,
FCC regulations prohibit using your cellular FWT while the plane is in the air.
Children
Do not allow children to play with your Phonecell to prevent damage to the unit.
Blasting Areas
Construction crews often use remote control RF devices to set off explosives.
Therefore, to avoid interfering with blasting operations, turn your Phonecell OFF
when in a "blasting area" or in areas posted: "Turn off two-way radio."
Antenna Care and Replacement
Do not use the FWT with a damaged antenna. If a damaged antenna comes into
contact with the skin, a minor burn may result. Have your antenna replaced by a
qualified technician immediately. Use only a manufacturer-approved antenna.
Unauthorized antennas, modifications, or attachments could damage the FWT
(Fixed Wireless Terminal) and will void the user's authority to operate the equipment.

SX4e GSM 1900 6USER MANUAL
Safety Information - continued
Potentially Explosive Atmospheres
Turn your Phonecell OFF when in any area with a potentially
explosive atmosphere. It is rare, but your Phonecell or its acces-
sories could generate sparks. Sparks in such areas could cause an
explosion or fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not
always, clearly marked. They include fueling areas such as gas
stations; below deck on boats; fuel or chemical transfer or storage facilities; areas
where the air contains chemicals or particles, such as grain, dust, or metal pow-
ders; and any other area where you would normally be advised to turn off your
vehicle engine.
Do not transport or store flammable gas, liquid or explosives in the area of your
Phonecell or accessories.
Vehicles using liquefied petroleum gas (such as propane or butane) must comply
with the National Fire Protection Standard (FPA-58). For a copy of this standard,
contact the National Fire Protection Association, One Batterymarch Park, Quincy,
MA 02269, Attn: Publications Sales Division.
FCC Part 15 Class B Compliance
This Phonecell SX4e model has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment OFF and ON, the user is
encouraged to try to correct the interference by one or more of the following
measures:
•• Reorient or relocate the antenna.
•• Increase the separation between the equipment and the terminal.
•• Connect the equipment into an outlet on a circuit different from that to which the
terminal is connected.
•• Consult your Authorized Telular Distributor or an experienced radio/TV
technician for help.
GSM Type Acceptance
The Phonecell SX4e GSM 1900 model utilizes a Telular-designed mobile terminal
integrated onto the main board. The Phonecell SX4e GSM 1900 model complies
with the TIA/EIA J-STD-007 PCS 1900 Air Interface Standard.

Dual-Jack Operation
The Phonecell SX4e may be operated in either
dual-jack or single-jack mode. The factory default
is the dual- jack mode. In dual-jack operation, for
outgoing calls, the first jack to seize the line (go
off-hook) will disconnect the other jack. The other
jack will remain disconnected until the first jack
goes back on-hook. For incoming calls, voice
calls will be routed to the Phone voice jack and
fax calls will be routed to the Fax jack. See How
to Set A Single Jack Option, to change program-
ming to single jack operation.
1) Locate the modular line port on your
phone and plug in one end of a standard
phone cord.
2) Connect the other end of the cord to the
telephone port (marked PHONE) on the side
of your Phonecell SX4e - see Figure 7.
NOTE: An RJ-11 connector will fit into the
Phone port.
NOTE: The Phonecell SX4e does not
support direct computer modem (data)
operation through the Phone port or Fax
port. It also does not support the phone
through the fax port.
3) Locate the modular line port on
your fax machine and plug in one end of a
standard phone cord.
4) Connect the other end of the cord
to the fax port (To the Left of the Phone
port) on the side of your Phonecell SX4e.
Single-Jack Operation
The analog fax jack can be disabled leaving
only the telephone jack operational (single-jack
operation). In single-jack operation, voice calls
can be placed and received normally if a tele-
phone is connected. If a fax is connected,
incoming analog fax calls can be received
normally, but to place outbound fax calls using
the voice jack, a bypass sequence must be
used as a prefix in the dialed telephone number.

Step 3. Optional PC Data Connection
The Phonecell SX4e features a DB-9 Digital Computer Fax/Data Port for connec-
tion to a Personal Computer (PC) – not supplied (see - Figure 10). When connected
to a PC, the Phonecell’s PC interface is capable of digital fax/data transmission at
speeds up to 9600 baud.
NOTE: A data cable (DB-9 to DB-9 or DB-25 to DB-9) is required for data transmis-
sion – not included. To determine the necessary cable, count the number of PIN
connections in the serial port of your PC (see below). If there are 9 PIN connections
in the PC serial port, a DB-9 (female) to DB-9 (male) cable is required. If there are
25 PIN connections in the PC serial port, a DB-25 (female) to DB-9 (male) cable is
required.
