Device Components and Operation

The system includes a charging case with charging contacts and a battery indicator LED. The transmitter/receiver unit features a charging contactor, a channel/battery display LED, and an ON-OFF / Channel Selection Key. It also has a transmitter/receiver sign and a charging indicator LED.

Powering On: Long press the ON-OFF / Channel Selection Key for 3 seconds to power on the device.

Connecting:

• The transmitter inserts into the output of a guitar, bass, or other instrument.
• The receiver inserts into the input port of an effector or loudspeaker, etc.

Battery Level Indication: A single click of the ON-OFF / Channel Selection Key displays the current battery level for 5 seconds. The number of illuminated LEDs indicates the battery percentage: 5 LEDs (80%-100%), 4 LEDs (60%-80%), 3 LEDs (40%-60%), 2 LEDs (20%-40%), 1 LED (1%-20%). When all LED lights are flickering, the transmitter/receiver needs to be charged.

Channel Management:

• Double Click: Enter Channel Selection Mode.
• Single Click: Switch Current Channel.
• Double Click: Confirm the Selected Channel.

Important: The transmitter and receiver must be set to the same channel to function correctly.

Charging

Charging the Transmitter/Receiver: When placed in the charging case, the charging indicator LED on the transmitter/receiver will remain lit until fully charged.

Charging Case Battery Status: When no transmitter/receiver is charging, opening the charging case will illuminate the power indicator LED for 5 seconds to show the current battery level of the case. The LEDs indicate the state of the battery and charging status:

Legend: ● LED Light On, ○ LED Light Off, ◑ LED Light Flickering

Caution and Warning

Caution: PLEASE READ CAREFULLY BEFORE USE

• When using multiple sets of transmitters and receivers, ensure they are set to the same channel to avoid interference and ensure normal operation.
• If the channel LED display is normal but there is no sound when the transmitter/receiver is powered on, please restart the transmitter and receiver.
