Radio Frequency (Rf) Exposure And Sar - MTX -GTW Hardware User's Manual

•
Never connect more than one modem to a single antenna. The modem can be damaged by
radio frequency energy from the transmitter of another modem.
•
Like any mobile station, the antenna of the modem emits radio frequency energy. To avoid
EMI (electromagnetic interference), you must determine whether the application itself, or
e uip e t i the appli atio 's p o i it , eeds fu the p ote tio agai st adio e issio
and the disturbances it might cause. Protection is secured either by shielding the surrounding
electronics or by moving the antenna away from the electronics and the external signal
cable.
•
The modem and antenna may be damaged if either come into contact with ground potentials
other than the one in your application. Beware: ground potentials are not always what they
appear to be.

8.5 Radio Frequency (RF) exposure and SAR

Your wireless modem device is a low-power radio transmitter and receiver (transceiver). When it is
turned on, it emits low levels of radio frequency energy (also known as radio waves or radio
frequency fields).
Governments around the world have adopted comprehensive international safety guidelines,
developed by scientific organizations such as ICNIRP (International Commission on Non-Ionizing
Radiation Protection) and IEEE (The Institute of Electrical and Electronics Engineers Inc.), through
periodic and thorough evaluation of scientific studies. These guidelines establish permitted levels of
radio wave exposure for the general population. The levels include a safety margin designed to
assure the safety of all persons, regardless of age and health, and to account for any variations in
measurements.
Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency energy
absorbed by the body when using a transceiver. The SAR value is determined at the highest certified
power level in laboratory conditions, but the actual SAR level of the transceiver while operating can
be well below this value. This is because the transceiver is designed to use the minimum power
required to reach the network.
The MTX-GTW wireless modem device has been approved for applications where the antenna is
located more than 20cm from the body. In all other configurations the user is responsible for
meeting the local SAR regulations.
