CAUTIONS AND TROUBLESHOOTING

23. Feedback

Observe care in selecting P.A. volume, transmitter location and speaker placement so that the 
acoustic feedback (howling and screeching) will be avoided. Please also note the pickup pattern 
characteristics of the microphone selected. Omni directional mics pick up sound equally from all 
direction, and are prone to feedback if not used carefully. 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, such as lavalier mics, required more acoustic gain and thus 
are also more prone to feed back than close-source mics such as handheld or headworn models 
that are used close to the mouth.

24. Microphone Damage

Headset and lavalier mic users: please note that the microphone element can easily be destroyed 
by the buildup of salts and minerals from perspiration and saliva. It is good practice to put a wind-
screen on the mic at all time to protect it and to keep it clean and dry at all times.

25. No Audio

If you are not getting audio through the system, carefully re-check all setups. Especially note that 
the receiver and transmitter must be set to operate on the same RF channel. Also confirm that the 
Audio Mute on the transmitter is in the Off position.

26. 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), often it can be overcome by adjusting the receiver ‘s squelch 
control (SQL).

If receiving interference on a selected channel with the transmitter off, you must reprogram the 
receiver and transmitter to a different channel (see sections 4, 6, 15, & 19). To reprogram, you must 
first find an open channel. To do this follow the operating procedure outlined in Section 4 above, 
and with the associated transmitter off, scroll through the groups/channels to find one that shows no 
received signal on the receiver LCD display’s received signal icon (no bars). Also there must be no 
bars either on each of the three immediately adjacent channels both below and above the selected 
channel for optimum interference-free operation (so field of 7 adjacent channel total—with channel 
used in the middle).  If operating multiple UWS-1K systems simultaneously, repeat this procedure 
with every new channel being selected, with previously tuned systems all ON, both transmitters and 
receivers.

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 non-government 
operation, the wireless microphone must be cease operation or change frequencies. The above 
statement is valid only for use in the U.S.A.
