Set Up Instructions

SET UP
There are many factors that can affect and/or interrupt the wireless UHF signal. These factors can include walls, glass, metal objects, other solid surfaces, 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), electronic appliances and people. Do not install this equipment in a high temperature or high humidity environment. To ensure optimal performance of the system, the working temperature should be between 23¡F (-5¡C) and 113¡F (45¡C).
Therefore, it is recommended to position the wireless receiver away from the above-mentioned items and a minimum of 3.0 ft. (1m) above audiences and/or above ground level. To allow for proper ventilation, the distances between equipment and objects around it should be no less than 8 inches (200mm). Careful planning and testing of the selected installation location is critical to ensure optimum and reliable wireless operation.

Note: In order to use two receivers (two sets of microphones) at a time, please use two different frequency models. If using multiple models with the same frequency range, please keep them at least 328 feet (100 meters) away from each other to avoid signal interference.
