Setup Instructions
Follow these steps to set up your WENTELMUSIC A8 Wireless Guitar System:
- Power On: Pull up the power switch on both the transmitter(s) and receiver to turn them on. The units will automatically attempt to pair.
- Switch Modes (Optional): If needed, press and hold the button on the transmitter for 3 seconds to switch between available modes.
- Connect to Instrument and Amplifier: Plug the transmitter unit(s) into your instrument's output jack. Plug the receiver unit into your amplifier's input. It is recommended to plug in the units first, then turn on the amplifier to avoid unwanted noise caused by metal friction during insertion.
- Verify Connection: A solid green or blue light on the receiver indicates a successful connection, depending on the instrument type (green for acoustic, blue for electric).
