4.1 Safety Advice and Precautions

4.1.1 General

• Always ensure that use of the modem is permitted. The modem may

present a hazard if used in proximity to personal medical electronic

devices. As a rule, the modem must not be used in hospitals, airports

or planes.

• Avoid exposing the modem to lighted cigarettes, naked flames or to

extreme hot or cold temperature.

• You are responsible for observing your country’s safety standards,

and where applicable the relevant wiring rules.

• Never use the modem at a gas station, refuelling point, blasting area

or in any other environment where explosives may be present.

• Operating the modem close to other electronic devices, such as

antennas, television sets, and radios may cause electromagnetic

interference.

• Never try to dismantle the modem yourself. There are no

components inside the modem that can be serviced by the user. If

you attempt to dismantle the modem, you may invalidate the

warranty.

• To protect power supply cables and meet the fire safety requirements

when the unit is powered from a battery or a high current supply,

connect a fast 1.25A fuse in line with the positive supply.

• Do not connect any incompatible component or product to the

GM29. 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.
