4. Setup

4.1. Charging the Devices

Both the transmitter and receiver have built-in 400mAh rechargeable lithium-ion batteries. Use the provided USB charging cable to charge them. A full charge takes approximately 2 hours and provides 5-6 hours of operation. The red light on the device will be on during charging and will turn off once fully charged.

4.2. Attaching the Microphone to an Instrument

The microphone transmitter features a 360-degree rotatable silicone shock-proof clip and a strong steel collar clip. This design allows for easy and secure attachment to various instruments, such as the bell of a saxophone or trumpet, while protecting the instrument from damage. The clip also helps filter noise caused by instrument vibration.

Correct Installation Guidelines:

• Ensure the microphone angle is approximately 45 degrees or greater (Angle ≥45°).
• Maintain a distance of 10cm or more from the instrument's sound source (Distance ≥10cm).

• Battery Care: To prolong battery life, avoid completely draining the battery frequently. Charge the devices regularly, even if not in use for extended periods.
• Microphone Head: The microphone head is protected by a foam cover. Ensure it remains intact to prevent dust and moisture from affecting sound quality.

7. Troubleshooting

7.1. No Sound Output

• Check Pairing: Ensure the transmitter and receiver are properly paired. If the receiver's blue light is still flashing, re-attempt the pairing process as described in Section 4.4.
• Check Connections: Verify that the receiver is securely plugged into the "Mic" input of your audio equipment. If using the 6.35mm adapter, ensure it is firmly connected.
• Check Volume: Make sure the volume on both the transmitter and your audio equipment is turned up.
• Battery Level: Confirm that both the transmitter and receiver have sufficient battery charge.
• Compatibility: Remember that the system is not compatible with Macbook, laptops, PCs, mobile phones, or Bluetooth speakers. Ensure you are connecting to a compatible audio device with a dedicated "Mic" jack.

7.2. Interference or Poor Sound Quality

• Distance: While the system has a range of up to 160 feet in open areas, obstacles can reduce this. Try to minimize physical barriers between the transmitter and receiver.
• Other Wireless Devices: Although UHF technology is designed to minimize interference, strong local wireless signals might still affect performance. Try changing the frequency on the transmitter if available, or move away from other wireless devices.
• Microphone Placement: Ensure the microphone is correctly positioned on the instrument, following the guidelines in Section 4.2, to optimize sound pickup and reduce unwanted noise.
