CHIAYO UDR-1000 - Manual (Page 2)

System Overview：
4、If the Volume Control of the receiver is set too high, it may over-drive the input of
the mixer, causing distortion. Conversely, if the receiver output is set too low, the
overall signal to noise ratio of the system may be reduced. Adjust the output level of
the receiver such that highest sound pressure level going into the microphone causes
no input overload in the mixer, and yet permits the mixer level controls to operate in
their normal range (not too high or too low ). This provides the optimum signal to
noise for the entire system.
5、When inserting the batteries, please make sure that they are inserted according
to the correct polarity.
6、For PLL frequencies agile version, before operation please make sure that the
corresponding receiver MUST have the same frequency group and channel number
as the transmitter.
7、Before making any channel change, please switch off the power supply. The
synthesized program works in such a way that a change of channel will only take
place after a power off and on action. Otherwise, the previously selected frequency
will stay unchanged.
8、After making a channel change, please make sure that the corresponding change
is made on the matching receiver also. To be exact, changes MUST be made at both
the transmitter and receiver.
9、Use only brand new Alkaline batteries. Do not use " general purpose " batteries.
When batteries are weak, replace the batteries altogether at the same time. Do not
mix and use new and old batteries together.
10、Position the receiver so that it has the least possible obstructions between it
and the transmitter. Line of sight is best!
11、The transmitter and the receiver should be as close as possible but not less than
1m.
12、A receiver cannot receive signals from two or more transmitters
simultaneously.
13、Turn the transmitter off when it is not in use. Remove the batteries if it is not to
be used for a period of time. INTRODUCTION
