•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.
