Your Phonecell SX4D GSM 900 and SX4D GSM 1800 Desktop Phones
function as both a radio transmitter and receiver. When it is ON, the Desktop
Phone receives and sends out radio frequency (RF) energy. The GSM 900
unit operates in the frequency range between 890 and 960 MHz, and the
GSM 1800 between 1710 MHz and 1880 MHz. Both employ commonly used
phase/frequency modulation techniques. When you use your Phonecell
SX4D Desktop Phone, the cellular system handling your call controls the
power level at which your unit transmits. Nominal power output for the GSM
900 unit is 2 watts and for the GSM 1800 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 SX4D 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 SX4D when any person is within 1 inch (2,5 cm) of the
antenna.
