Foam Windscreen and Fur Windshield

Using the foam windscreen can protect the microphone from dust and liquids. When using the wireless system outdoors in areas with strong wind, the fur windshield removes noise and distortion from your sound. Make sure to install it to the top of the microphone end to prevent the windshield from entering the microphone soundhole. ?️

Batteries and Charging

The wireless system comes with a dual USB charging cable, which charges the transmitter and the receiver simultaneously. Plug it into any 5V / 2A USB charger adapter or USB power source. ?

Note: Turn off the power before charging. Do not use the wireless system while charging, as this may reduce your battery life. ⚠️

• The battery is low and charging is required when the red LED is flickering. ?
• Always store at room temperature. ?
• When storing the unit for long periods, check the battery charge level regularly and charge if necessary. ?

Connect to a power supply or USB power outlet.

Charging Times and Battery Life

POWER STATUS LED: LED off = 100% ~ 30% | Solid red = 29% ~ 11% | Flickering red = less than 10%

2.4 GHz Wireless Overview and Interference

The U7, U8, and U9 wireless systems operate on the 2.4 GHz ISM band, which is also used by Wi-Fi, Bluetooth, and other wireless devices. 2.4 GHz is an open band and does not require a license for worldwide use. ?

Tips and Methods to Improve Wireless System Performance

1. Keep more than 3 metres (9.8 feet) of distance between the wireless system receiver unit and Wi-Fi transmitters, such as routers. ↔️
2. If you experience interference from Wi-Fi devices, try changing to a different channel on the wireless system transmitter and receiver. ?
3. If necessary, shorten the distance between the transmitter and receiver units. ?

2.4 GHz Frequency Tables

Note: U2 1~4 channels are the same as U3/U3C/U4/U7/U8/U9 1~4 channels. U2, U3/U3C/U4/U7/U8, and U9 can be used with a maximum of 6 sets at a time.

Troubleshooting

No Sound

• Check that the wireless system Receiver's RF LED is illuminated. ?
• Check that the microphone is connected and receiving signal from the wireless system Transmitter. ??
• Check that the power switches are turned on for both the Transmitter and the Receiver. ⚡
• Ensure that the Transmitter and Receiver are set to the same channel. ?
• The Receiver can be paired with only one Transmitter at a time.

Sound Too Low

• Adjust the microphone position. ?
• Increase the gain on the mixer. ?️

Signal Instability: RF LED flickering, or off completely

See, "Tips and Methods to Improve Wireless System Performance" on page 20. ℹ️

Unable to Switch the Channel

The channel switch locks after 15 seconds. Double-click the channel button to unlock and reset. ?️?️
