Common questions about manuals, registration, and support for this brand.
Turn off both the microphone and receiver. Hold the power/pair button on the microphone until the display flashes, then quickly turn on the receiver. The lights should stabilize when paired.
Typically, no. The receiver must be plugged into a dedicated MIC input (6.35mm or 3.5mm). Most Bluetooth speakers only have AUX inputs, which may result in low volume or no sound.
Check the batteries in the microphone. If the model supports adjustable channels, try switching to a different frequency to avoid interference.
