Cautions and Troubleshooting
Feedback
Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement.
Please also note the pickup pattern characteristics of the microphone selected. Unidirectional mics are more resistant to feedback. However, they pick up sound sources best that are directly in front of the mic. Also mics that are farther from the sound source require more acoustic gain and thus are also more prone to feed back than

RF Interference and
Finding Open Channels
If you encounter slight receiving interference when the transmitter is far from the receiver (from other than an operating TV station
on the same frequency), often it can be overcome by adjusting the receiver‘s Squelch Control (16) (see Adjusting the Squelch). If receiving interference on a selected channel with the transmitter off, you must reprogram the receiver and transmitter to a different channel.

Please note that wireless frequencies are shared with other radio services. According to FCC regulations, wireless microphone operations are unprotected from interference from other licensed operations in the band. If any interference is received by any Government or
Note: More bars in the Received Signal (39) icon indicate good signal strength in operation with the transmitter on, but more than 1 bar showing with the transmitter off also indicates the presence of likely RF interfering signals at that location. If this happens, select a different GRP/CH. One bar or less is ideal for
