SX4e GSM 1900 4 USER MANUAL
Safety Information
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 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. Do not block the air vents or the space beneath your Phonecell as
this could cause the unit to overheat and fail.
