Preliminary. Subject to change without prior notice 
• When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card holder. 
 
Caution! 
Do not touch these connectors! If you do, you may release an electrical discharge that could 
damage the modem or the SIM card. 
 
• 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. 
 
6.4. Antenna precautions 
 
If the antenna is to be mounted outside, 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 signals 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 potential are not always what they appear to be. 
 
6.5. 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, e.g. 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-H15 wireless modem device has been approved for applications where the antenna is located >20cm 
from the body. In all other configurations the integrator is responsible for meeting the local SAR regulations. 
 
Integrators of the MTX-H15 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. 
 
6.6. Personal Medical Devices 
 
Wireless modem devices may affect the operation of cardiac pacemakers, hearing aids and certain other 
implanted equipment. If a minimum distance of 15 cm (6 inches) is maintained between the MTX-H15 terminal 
radiating antenna and a pacemaker, the risk of interference is limited. If the integrator’s application is likely to 
be situated in the vicinity of personnel, a suitable warning should be contained in the equipment manual to this 
effect.
