Sony Ericsson GR64 - Manual (Page 76)

LZT 123 1834 76
Do not connect any incompatible component or product to the module.
Sony Ericsson does not warrant against defects, malfunction, non-
conformities or deviation caused by the connection of incompatible
components or products to the GR64.
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.
7.2 SIM Card
Before handling any SIM card, users should ensure that they are not charged with
static electricity. Use proper precautions to avoid electrostatic discharges. The
wireless modem 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 modem or the SIM card.
When designing applications, the SIM card’s accessibility should be taken into
account. Sony Ericsson 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 modem to a single antenna.
The wireless modem can be damaged by radio frequency energy from the transmitter
of another adjacent wireless transmitter.
Like any mobile station, the antenna of the wireless modem 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.
