How do I setup my wireless mic with my Voice Rover?

To use the included wireless mic, follow these setup steps:

  1. Ensure 2 new AA alkaline batteries are installed in the wireless mic. The microphone handle unscrews to reveal the battery compartment. Screw the handle back on with the threads facing inward.
  2. On the UHF Receiver panel on Voice Rover, turn on Power-Vol knob clockwise.
  3. Turn on the wireless microphone using the switch found on the bottom of the microphone. Watch the AF indicator to make sure a signal is being received.
  4. Use the Up or Down buttons to select a wireless channel that gives a strong signal.
  5. Hold the microphone close to your mouth when speaking and the AF LED will illuminate on the Wireless Mic Settings panel. Adjust the Power-Volume knob to increase the level.

    Note: If needed, the High/Low (H/L) switch on the wireless mic can be adjusted to increase the signal range. The High power setting consumes more battery power to provide extended range and reception. The Low setting extends battery life for use in scenarios where a lower operating range is acceptable. If needed, the gain adjustment on the microphone can be adjusted clockwise for more output gain. For less output gain, the screw can be adjusted counter-clockwise.
