4. Hints for Integrating the Module
This chapter gives you advice and helpful hints on how to integrate the
GM47 into your application from a hardware perspective.
Please read and consider the information under the following headings
before starting your integration work:
• Safety advice and precautions.
• Installation of the module.
• Antenna.
4.1 Safety Advice and Precautions
4.1.1 General
• Always ensure that use of the module is permitted. The module may
present a hazard if used in proximity to personal medical electronic
devices. As a rule, the module must not be used in hospitals, airports
or planes.
• You are responsible for observing your country’s safety standards,
and where applicable the relevant wiring rules.
• Never use the module at a gas station, refuelling point, blasting area
or in any other environment where explosives may be present.
• Operating the module close to other electronic devices, such as
antennas, television sets, and radios may cause electromagnetic
interference.
• Never try to dismantle the module yourself. There are no
components inside the module that can be serviced by the user. If
you attempt to dismantle the module, you may invalidate the
warranty.
• To protect the power supply cables and meet the fire safety
requirements, it is recommended that the electrical circuits are
supplied with a power regulator. The power regulator should be
placed as close to the terminals of the power supply as possible.
• Do not connect any incompatible component or product to the
GM47. Note, Sony Ericsson does not warrant against defects, non-
conformities or deviations caused thereby.
4.1.2 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 module must be switched off
before the SIM card is installed in your application.
