Speed Modes

The device supports two speed modes for volume adjustment:

• Default Mode: In this mode, Windows volume changes by 2% for each anchor point rotation of the knob. A full 0-100% adjustment requires 2 full laps of rotation. This mode offers finer control and is recommended for Android devices.
• High Speed Mode: In this mode, Windows volume changes by 4% for each anchor point rotation. A full 0-100% adjustment requires only 1 full lap of rotation. This mode provides faster adjustment and is suitable for headphones, laptop built-in speakers, or low-power speakers.

To switch between modes, press the knob and rotate it simultaneously. The LED breathing light will flash to indicate the current mode: two flashes for Default Mode, and ten flashes for High Speed Mode.

Night Mode

To activate Night Mode, press and hold the knob for more than 8 seconds. In Night Mode, the breathing light will remain steadily on, which is convenient for use in low-light environments.
