7. PRECAUTIONS ON ANTENNA INSTALLATION
• Keep the wireless microphone at least 3 m away from the antenna. Using the microphone close to the
antenna may cause malfunction or noise.
• Avoid installing the antenna to or near steel beam, lockers, and other metal objects. Besides, keep it at least
30 cm away from wall surfaces.
• Keep the unit as far away as possible from the following equipment that may generate high-frequency noise:
inverter-driven equipment (such as fluorescent lamps or air-conditioners), digital equipment, and computers.
• Never short antenna cables or the unit's antenna connectors. If they are shorted, the power supply to the
antenna shorts, possibly causing unit's failure.
• Install the antenna and the unit as close as possible to each other to minimize the coaxial cable length.
• Use the optional YW-4500 Antenna when mounting the unit in an equipment rack.
• Install the antenna cable referring to the following type of cable vs. permissible maximum length.
RG-6/U (diameter 8.4 mm): 35 m
RG-11/U (diameter 10.3 mm): 50 m
