SIM card precautions
Before handling the SIM card in your application, ensure that you are not charged with static
electricity. Use proper precautions to avoid electrostatic discharges.
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 considered. 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.

Antenna precautions
Consider the risk of lightning in case the antenna is to be mounted outside. Follow the instructions
provided by the antenna manufacturer.
NOTICE
Please note that this LTE device is designed for use with one single antenna only. It does not
support antenna diversity.
▪
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 is not always what it appears
to be.

Storage Conditions
The following environmental limits must be maintained in order to safely store the terminal and ensure
that it remains functional until a maximum of 12 months:
▪
Storage temperature: from 5°C to 35°C
▪
Humidity: <75% relative humidity.
