When using the modem care must be taken on safety issues related to RF interference as well as regulations of RF equipment. Do not use your phone in aircraft, hospitals, petrol stations or in places where using GSM products is prohibited. Be sure that the modem will not be interfering with nearby equipment. For example:
pacemakers or medical equipment. The antenna of the modem should be away from computers, office equipment, home appliance, etc. An external antenna must be connected to the modem for proper operation. Only used approved antennas with the modem. Please contact authorized dealer on finding an approved antenna. Always keep the antenna with minimum safety distance of 26.6 cm or more from human body. Do not put the antenna inside metallic box, containers, etc. Using the modem in vehicle Check for any regulation or law authorizing the use of GSM in vehicle in your country before installing the modem Install the modem by qualified personnel. Consult your vehicle dealer for any possible interference of electronic parts by the modem. The modem should be connected to the vehicles supply system by using a fuse-protected terminal in the vehicles fuse box Be careful when the modem is powered by the vehicles main battery. The battery may be drained after extended period. Protecting your modem To ensure error-free usage, please install and operate your modem with care. Do remember the following:
Do not expose the modem to extreme conditions such as high humidity/rain, high temperatures, direct sunlight, caustic/harsh chemicals, dust, or water. Do not try to disassemble or modify the modem. There is no user serviceable part inside and the warranty would be void. Do not drop, hit or shake the modem. Do not use the modem under extreme vibrating condition. Do not pull the antenna or power supply cable. Attach/ detach by holding the connector. Connect the modem only according to the instruction manual. Failure to do it will void the warranty.
