- Clip-on: Use the built-in clip to attach the transmitter to clothing, such as a collar or lapel.
- Magnetic: For discreet placement, use the provided magnetic clip to secure the transmitter under clothing.
Attach the fur windshields to the transmitters when recording in windy conditions to minimize wind noise.

Operating Instructions
1. Power On/Off
To power on the transmitters and receiver, simply remove them from the charging case. They will automatically power on and attempt to pair. To power off, place them back into the charging case or long-press the power button on each unit.
2. Smart Touchscreen Interface (Receiver)
The receiver features a 0.96-inch OLED touchscreen for intuitive control and monitoring. Swipe to access settings and view:
- Battery status of both transmitters and the receiver.
- Connection status.
- Audio levels.
- Current recording mode (Mono/Stereo/Safety Track).
- Noise cancellation mode.

3. Noise Cancellation Modes
The S20 offers dual AI noise cancellation modes:
- Basic Mode: Ideal for quiet indoor environments, providing clear audio without aggressive noise reduction.
- Strong Mode: Effectively suppresses background noise in loud settings, such as outdoors or in crowded areas.
Switch between modes via the touchscreen or dedicated function button on the transmitter to adapt to your recording environment.

4. Recording Modes
The system supports three recording modes for creative flexibility:
- Mono Mode: Combines both transmitter audio into a single channel.
- Stereo Mode: Records each transmitter's audio to a separate channel (left and right), allowing for post-production mixing.
- Safety Track Mode: Records a secondary audio track at -6dB lower than the main track. This acts as a backup to prevent clipping or distortion if the main audio levels become too high.
Switch between these modes using the receiver's touchscreen or the function button on the transmitter.

5. Gain Control
Adjust the audio input gain using the rotary control on the transmitter. This allows you to fine-tune the microphone's sensitivity to match your recording environment and speaker's voice, preventing audio that is too quiet or too loud.

6. Wireless Range
The PQRQP S20 offers a stable wireless transmission range of up to 820 feet (250 meters) in open environments, utilizing 2.4GHz technology for ultra-low latency. This allows for significant mobility during recording without compromising audio quality.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the microphone transmitters, receiver, and charging case. Avoid using liquid cleaners or solvents.
- Storage: Store the system in its charging case when not in use to protect it from dust and damage, and to keep it charged.
- Battery Care: For optimal battery life, avoid fully discharging the units frequently. Charge them regularly, even if not in constant use.
- Windshields: Clean fur windshields gently by shaking or using a soft brush to remove debris. Do not wash them with water.
Troubleshooting
No Sound or Low Volume
- Ensure the receiver is securely connected to your recording device.
- Check that both transmitters and the receiver are powered on.
- Verify the audio input settings on your recording device (camera, smartphone, PC) are correctly configured to use the external microphone.
- Adjust the gain control on the transmitter to increase the input volume.
- Check the battery levels of all units on the receiver's touchscreen.
Poor Audio Quality / Background Noise
- Ensure the transmitter is positioned correctly, close to the sound source.
- Activate the 'Strong' AI noise cancellation mode in noisy environments.
- Attach the fur windshields when recording outdoors or in windy conditions.
- Check for potential interference sources (e.g., other 2.4GHz devices) and try to move away from them.
- If experiencing clipping, switch to Safety Track mode or reduce the gain on the transmitter.
Connection Issues
- Ensure transmitters and receiver are within the specified operating range (up to 820ft/250m).
- Confirm that all units are fully charged.
- Power cycle the transmitters and receiver by turning them off and on again.
- Avoid physical obstructions between the transmitters and receiver that could block the signal.
