171.802UK User Manual
If the wireless system is not to be used for more than a few seconds, it is preferable to slide the transmitter switch to the
“OFF” position, which mutes and deactivates the radio signal and powers down the transmitter. Be sure to turn down the
volume of the mixer or amplifier and then switch off the receiver. Unplug signal leads from the receiver and mixer or
amplifier when moving or packing away.
If the system is not to be used for long periods of time, remove the batteries from the transmitter and unplug the power
adapter from the receiver and the mains outlet. Retracting the antennae can also help avoid damage when the system is
not in use.
