Operating Instructions
Channel Synchronization:
The MR-823 system typically features automatic frequency synchronization. Once the receiver and microphones are powered on, they should automatically link to an available clear channel. Refer to the receiver's display for channel information.
Adjusting Volume:
Use the individual volume control knobs on the front panel of the receiver to adjust the output level of each microphone. Start with a low volume and gradually increase it to avoid feedback or distortion.
Microphone Usage:
- Hold the microphone approximately 2-6 inches from your mouth for optimal sound pickup.
- Avoid covering the microphone grille with your hand, as this can affect sound quality and signal strength.
- Ensure a clear line of sight between the microphones and the receiver for best wireless performance.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the receiver and microphones. Do not use liquid cleaners or abrasive chemicals.
- Battery Replacement: Replace microphone batteries when the low battery indicator appears or when audio quality degrades. Always use fresh, high-quality batteries.
- Storage: When not in use for extended periods, remove batteries from the microphones and store the system in a cool, dry place, away from direct sunlight and extreme temperatures.
- Antenna Care: Handle antennas carefully to avoid bending or breaking.
