Do not spill liquid on the appliance and do not drop it on a hard concrete floor.
"
Do not place the appliance near heat sources such as radiators, amplifier, or etc.
Do not expose it to direct sunlight, extremely dust, excessive mOisture, or vibration.
Take out the battery from transmitter, if the appliance has been not used for a longer
period. This will avoid the damage resulting from a defective leaking battery.

Before setting up, make sure that the transmitter and receiver are tuned to the same
frequency.
Do not use two transmitters in the same frequency.
Use good quality batteries to avoid the damage resulting from a defective leaking battery.
Turn the MIC/LiNE switch on the rear of receiver to adjust receiver output level to match
input level requirements of an audio mixer or amplifier.
While checking sound, move the transmitter around the area where you use the system to
look for dead spots. If you find any dead spot, change the receiver position. If it does
not work, avoid such places.
To avoid interference, do not put the receiver too near metal object and avoid obstructions
between transmitter and receiver.
Avoid the interference from TV, radio, other wireless appliances and etc.
