• When designing your application, the SIM card’s accessibility should be taken into account. We
always recommend that you have the SIM card protected by a PIN code. This will ensure that
the SIM card cannot be used by an unauthorized person.
4. Antenna Precautions
If the antenna is to be mounted outside the device, consider the risk of lightning. Follow the instructions
provided by the antenna manufacturer.
• 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
equipment in the application’s proximity, needs further protection against radio emission 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 of them come into contact with ground
potentials other than the one in your application. Beware: ground potentials are not always
what they appear to be.
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-StarEnergy-E wireless modem device has been approved for applications where the antenna is
located more than 20cm from the body of the user. In all other configurations the user is responsible for
meeting the local SAR regulations.
Users of the MTX-StarEnergy-E wireless modem device are responsible for ensuring that they meet the
SAR regulatory requirements of the countries in which they intend to operate the device and that their
documentation contains the relevant SAR declaration, certification information and user guidance as
appropriate.
