1. Introduction
The M-VAVE WP-3 is a 5.8G wireless audio transmission system designed for electronic instruments, offering a reliable and high-quality wireless connection. This system features low noise, minimal latency, high resolution audio, and a long transmission range, allowing musicians greater freedom of movement during performances and practice.

2. Setup Instructions
2.1 Charging the Devices
Before initial use, ensure both the transmitter and receiver are fully charged. Use the provided 1-in-2-out USB charging cable to charge both units simultaneously. A full charge takes approximately 1.5 hours and provides up to 8 hours of continuous use.
- Connect the USB charging cable to a standard USB power adapter (not included).
- Connect the two output ends of the cable to the charging ports on the transmitter and receiver.
- The LED indicator will show charging status (typically red while charging, turning off or green when fully charged).
2.2 Connecting to Instruments and Amplifiers
The WP-3 system is designed for plug-and-play operation, eliminating the need for complex settings.
- Transmitter (TX): Plug the transmitter into your instrument's output jack (e.g., electric guitar, bass). The 1/4" plug is rotatable by 190° to accommodate various instrument designs.
- Receiver (RX): Plug the receiver into your amplifier, mixer, or other audio input device.

2.3 Channel Selection
The WP-3 supports 4 channels, allowing up to 4 sets of devices to work simultaneously without interference. Both the transmitter and receiver must be set to the same channel.
- Turn on both the transmitter and receiver.
- Press the 'CHANNEL' button on both units to cycle through the available channels (indicated by LED lights).
- Ensure the transmitter and receiver are on the same channel for proper operation.
3. Operating Instructions
3.1 Powering On/Off
- To power on, press and hold the power button on both the transmitter and receiver until the LED indicators light up.
- To power off, press and hold the power button on both units until the LED indicators turn off.
3.2 Usage
- Once both units are powered on and on the same channel, the system will automatically pair.
- The 5.8G wireless band provides stable and reliable transmission, avoiding congestion from 2.4G/UHF bands.
- The effective range is up to 30 meters outdoors and 15 meters through walls. Actual range may vary depending on the RF environment, including reflections, interference, and absorption.

4. Maintenance
4.1 Battery Care
- Charge the devices regularly, especially if they will not be used for an extended period, to maintain battery health.
- Avoid completely draining the battery frequently.
- If the transmitter or receiver's LED is red, it indicates a low battery and requires charging.
4.2 Cleaning and Storage
- Wipe the units with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Store the system in a cool, dry place, away from direct sunlight and extreme temperatures.
- Use the provided storage bag to protect the units from dust and scratches when not in use.
5. Troubleshooting
5.1 No Sound or Intermittent Audio
- Check Power: Ensure both the transmitter and receiver are powered on and have sufficient battery charge. The LED indicator will be red if the battery is low.
- Check Channel: Verify that both the transmitter and receiver are set to the same channel.
- Check Connections: Ensure both units are securely plugged into the instrument and amplifier/audio input.
- Range: Make sure the transmitter and receiver are within the effective operating range (30m outdoor, 15m wall distance). Obstacles and other wireless devices can affect range.
- Interference: While 5.8G is less congested, other 5.8G devices or strong RF signals can cause interference. Try changing to a different channel.
5.2 Charging Issues
- Ensure the USB cable is properly connected to both the devices and the power source.
- Try using a different USB power adapter or port.
- If the LED indicator does not light up when charging, contact support.
