Operational Hints:
The wireless microphone works in a certain distance. When the transmitter user
moves in a facility, signal dropouts (momentary losses of signal reception) may
be encountered. These dropouts are caused by the building's architectural design
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.
