- Power On: Press the power button on the receiver. The display screens should illuminate. Then, press the power button on each microphone to turn them on.
5. Operating Instructions
5.1 Mode Selection (UHF vs. True Diversity)
The system supports two operational modes: 4-channel UHF mode and 2-channel true diversity mode. True diversity mode offers enhanced signal stability and an extended range.
- 4-Channel UHF Mode: Provides a working range of up to 260 feet (approximately 80 meters).
- 2-Channel True Diversity Mode: Provides a working range of up to 390 feet (approximately 120 meters).
To switch between modes, use the intelligent switching circuit button on the receiver. Refer to the receiver's display for the current mode indication.

5.2 IR Synchronization (Pairing)
The system uses infrared (IR) synchronization to pair microphones with the receiver channels.
- Ensure both the receiver and the desired microphone are powered on.
- On the receiver, select the channel you wish to pair.
- Press the 'SET' button on the receiver to initiate IR pairing mode for that channel.
- Align the IR sensor on the microphone with the IR sensor on the receiver.
- The microphone and receiver will synchronize automatically within seconds. The display on both units will confirm successful pairing.

5.3 Frequency Adjustment and Auto Search
The system offers 100 groups of frequencies to minimize interference. You can manually adjust frequencies or use the auto-search function.
- Manual Frequency Adjustment: Use the 'SET' and 'ADJ' buttons on the receiver to navigate to the frequency setting for a specific channel and manually select a desired frequency.
- Automatic Search Frequency: The receiver can automatically scan for available, clear frequencies. Access this function via the 'SET' and 'ADJ' buttons. This helps avoid interference.

8. Troubleshooting
If you encounter issues with your XTUGA M-6604S system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from microphone | Microphone not powered on; low batteries; microphone not paired; receiver output not connected or volume too low. | Ensure microphone is on and has fresh batteries. Perform IR pairing. Check receiver's audio output connection and volume levels on both receiver and connected audio equipment. |
| Intermittent signal or dropouts | Interference from other wireless devices; distance too far; obstacles blocking signal; antennas not positioned correctly. | Change frequency using auto-search or manual adjustment. Ensure antennas are vertical and unobstructed. Reduce distance between microphone and receiver. Switch to True Diversity mode for extended range if applicable. |
| Microphone muted and cannot unmute | Accidental mute activation on microphone. | Check the microphone's power/mute button. Some microphones may have a dedicated mute function. Refer to the microphone's specific controls. |
| Receiver settings are locked | Lock function activated. | Long-press the 'ADJ' button on the receiver to unlock the settings. |
