SX4e TDMA 800 • SX4e Tri-Mode 20 Technical Manual
GENERAL INFORMATION AND SAFETY
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)
Your Phonecell SX4e FWT (Fixed Wireless Terminal) functions as both a radio transmitter and receiver.
When it is ON, the FWT receives and sends out radio frequency (RF) energy. The Phonecell SX4e 800
operates in the frequency ranges of between 824 MHz and 894 MHz. The Phonecell SX4e Tri-Mode
operates in the frequency ranges of between 824 MHz and 894 MHz (Digital TDMA and analog AMPS)
and between 1850 MHz and 1990 MHz (Digital PCS). It employs 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.
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 expo-
sure 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 complies with this updated Standard. Of course, if you want to
limit RF exposure even further 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 SX4e when any person is within 203 mm (8 inches) of the antenna.
Antenna Care and Replacement
Do not use the Phonecell SX4e 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 dam-
age the Phonecell SX4e.
Driving
Check the laws and regulations on the use of cellular products in the areas where you drive. Some juris-
dictions 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.
Exposure to 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 SX4e 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.
IMPORTANT!
To ensure safe and efficient operation, please read the following information and observe these guidelines whenever using your
Phonecell SX4e.
WARNING!
Only Authorized Service Personnel should remove the cover of your Phonecell. For further assis-
tance, contact your Authorized Telular Representative. Please have the model and serial number
ready (model and serial numbers are located on the label on the bottom of the unit).
