2. Operating Instructions
2.1 Auto Scan and IR Synchronization
- Initiate Auto Scan: On the receiver, long press the SET button (2s) for the desired channel to initiate auto-scan. The system will automatically search for the least interference frequency.
- IR Sync: Once a new frequency appears on the receiver's display, tap the SET button again. Vertically aim the IR window of the handheld microphone towards the IR sensor on the receiver to pair them up. The microphone's display will update to match the receiver's frequency.

3. Maintenance
- Battery Replacement: The handheld microphones use 2x AA batteries each, providing up to 16 hours of use. Replace batteries when the indicator shows low power.
- Microphone Handling: For optimal sound capture and to prevent feedback, keep the microphone about 1-2 inches (3-5 cm) away from your mouth.
- Cleaning: Regularly clean the microphone grilles and receiver surfaces with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
4. Troubleshooting
4.1 Common Issues & Solutions
- Cutoffs and Static Noises: If you experience cutoffs or static noises, it might be due to a complex signal environment. Use the auto-scan function to find a clear frequency. For persistent issues, consider upgrading to a True Diversity wireless microphone system (e.g., PTU-1U or PTAU-2) for stronger interference resistance.
- Extending Operating Range: To extend the operating range beyond 328ft, we recommend using the PAS-225X antenna distribution system. It enhances signal strength and coverage. Avoid placing personal electronics near the receiver and ensure proper microphone placement to prevent feedback.
- Computer Connection: To connect the wireless system to a computer, first connect the system to a mixer, and then connect the mixer to your computer via its USB port. Select the mixer as the audio input device on your computer.
Description: This FAQ explains that cutoffs and static noises might be due to a complex signal environment and recommends upgrading to True Diversity wireless microphone systems like PTU-1U or PTAU-2 for stronger interference resistance.
