Safety Instruction And Guideings
*Do not shake device,avoid brute force when operating device.
*Do not operate device if the power cord has become frayed,crimped and/or damaged. If the power coed is damaged,replace it immediately with a new one of similar power rating.
*Only use accessories that are specified by the manufacturer.
*User the original packing and materials to transport.
Installation Location Guidelines
There are many factors that can affect and interrupt the wireless signal. These factors can include walls,metal objects and surfacrs,other digital or electronic devices (CD/DVD/Media players,computers,laptops,Wi-Fi devices,cell phones,wireless phones,two-way radio communication devices,and wireless remote controls), electronices,and people.
Therefore it is highly recomended to position the wireless receiver away from the above-mentioned items and a minimum 1 m above audiences and above ground level. careful planning and testing of the selected installation location is critical to ensure optimum and reliable wireless operation.
