The TT4031 (SE-GM29) must not be installed or located where the surface temperature of the plastic case may exceed 85ºC.

All cables connected to the TT4031 (SE-GM29) must be secured or clamped, immediately adjacent to the modem's connectors, to provide strain relief and to avoid transmitting excessive vibration to the modem in the installation.

Ensure the d.c. cable, supplying power to the, TT4031 (SE- GM29) does not exceed 3 metres. For longer distances please contact Sony Ericsson (see “Service and Support”).

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 TT4031 (SE-GM29).

Note! Sony Ericsson may refuse warranty claims where evidence of product misuse is found.

4.3SIM Card Precautions

Before handling the SIM card in your application, ensure that you are not charged with static electricity. Use proper precautions to avoid electrostatic discharges.

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 modem 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.

4.4Antenna Precautions

If the antenna is to be mounted outside, consider the risk of lightning. Follow the instructions provided by the antenna manufacturer.
