Telular SX4D Safety Information, Exposure to RF Radio Frequency Energy, Temperature Environment

Safety Information

IMPORTANT!

To ensure safe and efficient operation, please read the following information and observe these guidelines whenever using your Phonecell SX4D.

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.

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 SX4D 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 SX4D as this could cause the unit to overheat and fail.
