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.

Before 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 such 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.
