SAFETY PRECUTIONS
zThe modem generates radio frequency (RF) power. When using the modem care must be taken on
safety issues related to RF interference as well as regulations of RF equipment.
zDo not use your phone in aircraft, hospitals, petrol stations or in places where using GSM products is
prohibited.
zBe 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.
zAn external antenna must be connected to the modem for proper operation. Only uses approved
antenna with the modem. Please contact authorized dealer on finding an approved antenna.
zAlways 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
zCheck for any regulation or law authorizing the use of GSM in vehicle in your country before installing
the modem
zInstall the modem by qualified personnel. Consult your vehicle dealer for any possible interference of
electronic parts by the modem.
zThe modem should be connected to the vehicle’s supply system by using a fuse-protected terminal in
the vehicle’s fuse box
zBe careful when the modem is powered by the vehicle’s main battery. The battery may be drained after
extended period.
Protecting your modem
zTo ensure error-free usage, please install and operate your modem with care. Do remember the
following:
zDo not expose the modem to extreme conditions such as high humidity/rain, high temperatures, direct
sunlight, caustic/harsh chemicals, dust, or water.
zDo not try to disassemble or modify the modem. There is no user serviceable part inside and the
warranty would be void.
zDo not drop, hit or shake the modem. Do not use the modem under extreme vibrating condition.
zDo not pull the antenna or power supply cable. Attach/ detach by holding the connector.
zConnect the modem only according to the instruction manual. Failure to do it will void the warranty.
zIn case of problem, please contact authorized dealer.
