Important Safety Information
This chapter provides important information about safety procedures. For your safety and that of your equipment, follow these rules for handling your device.
Warning
Incorrect storage or use of your device may void the manufacturer’s warranty. Failure to follow these safety instructions could result in fire, electric shock, or other injury or damage.
Always take the following precautions.
Disconnect the power plug from AC power source or if any of the following conditions exist:
the power cord or plug becomes frayed or otherwise damaged
you spill something into the case
the device is exposed to rain or any other excess moisture
the device has been dropped or the case has been otherwise damaged
Be sure about that the use of this product is allowed in your country and in the environment required. As with any other telecommunication equipment, the use of this product may be dangerous and has to be avoided in the following areas: ď‚· where it can interfere with other electronic devices located in close proximity in environments such as hospitals, airports, aircrafts, etc.; where there is risk of explosion such as gasoline stations, oil refineries, etc.
It is responsibility of the user to enforce the country regulation and the specific environment regulation.
Do not disassemble the product; any mark of tampering will compromise the warranty validity.
Every device has to be equipped with a proper antenna with specific characteristics. The antenna has to be installed with care in order to avoid any interference with other electronic devices and has to be installed with the guarantee of a minimum 31cm (12.2 inches) distance from the body. In case of this requirement cannot be satisfied, the system integrator has to assess the final product against the SAR regulation.
DISCLAIMER: The manufacturer is not responsible for any damages caused by inappropriate installation, not maintaining the proper technical condition or using a product against its destination.
