4.HINTS FOR INTEGRATING THE MODEM
•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.
4.1.3 Antenna
•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.
•In the final application, the antenna must be positioned more than 20cm away from human bodies. When this rule cannot be applied, the application designer is responsible for providing the SAR measurement test report and declaration.
4.2Installation of the Modem
4.2.1 Where to Install the Modem
There are several conditions which need to be taken into consideration when designing your application as they might affect the modem and its function. They are:
Environmental Conditions
The modem must be installed so that the environmental conditions stated in the Technical Data chapter, such as temperature, humidity and vibration are satisfied. Additionally, the electrical specifications in the Technical Data section must not be exceeded.
