Operation
Single SENDER with Single RECEIVER or WIRELESS AMPLIFIER
With all units connected and powered, press and hold the button labeled M on the SENDER. After holding the M button for a
few seconds, the power indicator will begin blink green/blue. Release the M button. While the power indicator is blinking,
press and hold the M button on the RECEIVER or WIRELESS AMPLIFIER, until the receiver power button begins to blink
green/blue. Release the M button. The power buttons on both devices will continue to blink, and then turn steady blue. At
this time, the two devices are in sync and ready for use.
Note:
If you are using the wireless amplifier, and you have no sound source connected to the SENDER, the power indicator on
the amplifier will turn back to steady green, while the SENDER is steady blue. These units are actually in sync, the amplifier is
simply waiting for a sound source. Once audio is delivered to the SENDER, the indicator on the WIRELESS AMPLIFIER will
change to blue, and power-on the amplifier.
