SYSTEM OPERATION
(Note: The UH transmitter CAP (7) must be removed before installing the USB
cable.) (Note: Only one transmitter can be used with one UHF-1000 receiver. It
is not possible to use two transmitters on the same frequency and mix the
output of these transmitters into one wireless receiver. If you have any
questions, please contact the Nady Systems Customer Service Department.
See SERVICE section, pg. 21.)
CAUTIONS AND TROUBLESHOOTING
Feedback
Observe care in selecting P.A. volume, transmitter location and speaker
placement so that 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 directions, and are prone
to feedback if not used carefully. Unidirectional mics are more resistant to
feedback, but pick up sound sources best that are directly in front of the mic.
Also, mics that are farther from the sound source, such as lavaliers, require
more acoustic gain and thus are also more prone to feedback than close-source
mics such as handheld or headworn models that are used close to the mouth.
Microphone Damage
Headset and lavalier mic users, 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 windscreen on the mic at all times to protect it.
No Audio
If you’re not getting audio through the system, carefully check all setup. The
receiver and transmitter must be set to operate on the same RF channel.
RF Interference
If you encounter receiving interference (from other than an operating TV
station), often it can be overcome by adjusting the receiver’s squelch control.
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 cease operation or change frequencies. The above statement
is valid only for use in the U.S.A.
