HINTS FOR INTEGRATING THE RADIO DEVICE
54
LZT 123 8020 R1A
• The connection/disconnection method for the development
board is by means of the DC power jack. For this reason,
the mains supply should be situated close to the
development board and be easily accessible.
7.1.2 SIM Card
• Before handling the SIM card in your application, ensure that
you are not charged with static electricity. Use proper
precautions to avoid electrostatic discharges. The radio
device must be switched off before the SIM card is installed
in your application.
• 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
radio device 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.
7.1.3 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 radio device to a single
antenna. The radio device can be damaged by radio
frequency energy from the transmitter of another radio
device.
• Like any mobile station, the antenna of the radio device
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 radio device 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.
