(1) The microphone's service distance is 3-150 m. When the microphone user moves in a facility, signal
dropouts (momentary losses of signal reception) may be encountered. These dropouts are caused by the
building's architectural designs or materials which block the travel of or reflect the radio signal. If this
occurs, the user needs to change locations for better signal reception.

(2) The proper operation of your wireless system may be interfered with by other system operating on the
same frequency. In such cases, change the operating frequency of your system. It is recommended that
the Scan function (of the WT-4800) be used to avoid the frequency interference, which always searches
and shows idle frequencies.
