Operation
To begin, insert batteries into the transmitter. Slide the front half of the beltpack upwards just enough to reveal the battery compartment and position the supplied 9V battery inside (ensure + and – are the correct way around) and then slide the beltpack case together as before.
Position the receiver within the best available line of sight to the transmitter(s) and connect the DC jack of the supplied power adapter to the receiver and the plug-top to the mains outlet. Extend both antennas fully upwards and outwards slightly and switch the power on. Turn the output level down on the receiver.
Connect the jack or XLR (optional) lead to the receiver’s audio output connector, turn down the volume of the guitar amplifier (or effect unit) that the signal will be fed into and then connect the jack or XLR to the guitar amplifier. Move the slide switch on the beltpack transmitter to the first notch (MUTE) the LED should light momentarily (continuous dim LED indicates low battery). Move on another notch (ON) and gradually increase the output level on the receiver, then increase the volume on the guitar amplifier until the sound from the guitar can be heard through the amp (ensuring guitar volume controls are turned up)
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 guitar 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.
