•The GTR64 Terminal must not be installed or located where the surface temperature of the plastic case may exceed 85°C.

•All cables connected to the GTR64 Terminal 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 GTR64 Terminal, does not exceed 3 metres.

•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 GTR64 Terminal.

Note! GTR64 distribuitors and sales offices may refuse warranty claims where evidence of product misuse is found.

6.3. SIM 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.

6.4. Antenna precautions

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

•Never connect more than one modem to a single antenna. The modem can be damaged by radio frequency energy from the transmitter of another modem.

•Like any mobile station, the antenna of the modem emits radio frequency energy. To avoid EMI (electromagnetic interference), you must determine whether the application itself, or equipment in the application’s proximity, needs 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.

•The modem and antenna may be damaged if either come into contact with ground potentials other than the one in your application. Beware, ground potential are not always what they appear to be.

6.5. Radio Frequency (RF) exposure and SAR

Your wireless modem device is a low-power radio transmitter and receiver (transceiver). When it is turned on, it emits low levels of radio frequency energy (also known as radio waves or radio frequency fields).

Governments around the world have adopted comprehensive international safety guidelines, developed by scientific organizations, e.g. ICNIRP (International Commission on Non-Ionizing Radiation Protection) and
