SIM Card

Before handling any SIM card, users should ensure that they are not charged with
static electricity.
Wireless CPU must be switched off before the SIM card is installed or uninstalled.
When the SIM card holder is opened, the SIM card connections lie exposed under the
SIM card holder.
CAUTION: Do not touch these connections! Failure to heed this advice may release an
electrical discharge that could damage the Wireless CPU or the SIM card.
When designing applications, the SIM card's accessibility should be taken into
account. Wavecom recommends that users protect SIM card access by a PIN code.
This will ensure that the SIM card cannot be used by an unauthorized person.
7.3

Antenna

If the antenna is to be mounted outside, consider the risk of lightning.
Always follow the instructions provided by the antenna manufacturer.
Never connect more than one Wireless CPU to a single antenna.
The Wireless CPU can be damaged by radio frequency energy from the transmitter of
another adjacent wireless transmitter.
Like any Wireless CPU, the antenna of the Wireless CPU emits radio frequency energy.
To avoid EMI (electromagnetic interference), users must determine whether the
application itself, or equipment in the application's proximity, requires 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 Wireless CPU and antenna may be damaged if either come into contact with
ground potentials other than the one in the user's application.
potential are not always what they appear to be.
In the final application, the antenna must be positioned more than 20 cm away from
human bodies.
responsible for providing the SAR measurement test report and declaration.
Even if SAR measurements are not required, it is considered good practice to insert a
warning in any manual produced, indicating it is a radio product and that care should
be taken.
