4. Operating Instructions

4.1 Basic Operation

• Power On/Off: Use the 'ON/OFF' switch on the receiver and the power switch on each microphone to turn the units on or off.
• Volume Control: Adjust the volume for each microphone independently using the 'VOL A' and 'VOL B' knobs on the receiver.
• Signal Indicators: The 'RF' (Radio Frequency) indicator on the receiver will light up when a microphone is connected and transmitting. The 'AF' (Audio Frequency) indicator will light up when audio is being received.

4.2 Changing Frequency Channels

If you experience interference, you can change the operating frequency of the microphones:

1. On the microphone, locate the channel selection button (usually near the display).
2. Press the button to cycle through the available 96 frequency channels.
3. Observe the receiver's 'RF' indicator. When a clear channel is selected, the 'RF' indicator should be stable, and the audio quality should improve.
4. Ensure both the microphone and receiver are on the same channel for proper operation.

4.3 Optimal Performance Tips

• Maintain a clear line of sight between the microphones and the receiver whenever possible.
• Avoid placing the receiver near large metal objects or other electronic devices that may cause interference.
• Keep the operating distance within 50 meters for best performance.
• Regularly check microphone battery levels to prevent unexpected power loss during use.

5. Maintenance

5.1 Cleaning

• Wipe the receiver and microphones with a soft, dry cloth.
• Do not use liquid cleaners or abrasive materials, as they may damage the finish or internal components.
