3. Setup
- Charge the Units: Before first use, fully charge both the transmitter and receiver using the provided USB cable. The indicator light will show charging status and turn off or change color when fully charged.
- Connect the Transmitter: Plug the transmitter unit (marked 'TX') into your instrument's output jack (e.g., electric guitar, bass).
- Connect the Receiver: Plug the receiver unit (marked 'RX') into the input of your amplifier, pedalboard, or audio interface.
- Power On: Turn on both the transmitter and receiver units. The transmitter will automatically select the best available channel.
- Automatic Pairing: The receiver will automatically connect to the transmitter. Indicator lights on both units will confirm a successful connection.

4. Operating Instructions
Basic Operation:
- Ensure both units are charged and powered on.
- Verify the indicator lights confirm a stable connection.
- Adjust the volume on your instrument and amplifier as usual.
Multi-Receiver Setup (One-to-Many):
The QWS-10 system supports one transmitter broadcasting to a maximum of six receivers simultaneously. This is useful for scenarios where multiple amplifiers or monitoring systems need to receive the same instrument signal.
- Connect the transmitter to your instrument.
- Connect each receiver to its respective amplifier or audio input.
- Power on the transmitter first, then each receiver. All receivers will automatically connect to the single transmitter.
Note: This system does NOT support multiple transmitters connecting to a single receiver, or multiple transmitters operating simultaneously with multiple receivers in a complex setup. Only one transmitter can be active at a time for a given set of paired receivers.

5. Maintenance
- Charging: Recharge the units when the battery indicator shows low power. Use the provided USB cable and a standard USB power adapter (not included). Avoid overcharging by disconnecting once fully charged.
- Cleaning: Wipe the units with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures.
- Joint Durability: The rotating joint is designed for durability, withstanding over 5000 rotations. Handle with care to prolong its lifespan.
