Top button

• Short press: Stop (media_key_stop)
• Long press: Play from beginning (key_media_period or "." key)
• Extralong press: Adjust the number of volume steps (2 → 3 → 1)
  To confirm, the yellow LED flashes according to the selected level:
  1 flash = 1 step
  2 flashes = 2 steps
  3 flashes = 3 steps
  
  This function is particularly helpful on tablets and smartphones, as the standard volume steps are often too small to quickly achieve a noticeable change.
  Alternatively, on laptops, the volume control can be customized using AutoHotkey (implemented from version 09.02.2026).

Rotary control

• Rotary function
  Turning the control sends a volume command depending on the direction:
  Decrease volume (key_media_volume_down)
  Increase volume (key_media_volume_up)
• Button function (push button)
  The rotary control also functions as a push button:
  • Short: Play/Pause (key_media_play_pause)
  • Long: Next track (key_media_next_track)
  • Very long: Reverse rotation direction
    After successfully reversing the rotation direction, the yellow LED flashes twice to confirm (implemented from version dated 09/02/2026).

Status LED

• Flashing yellow: Device is ready for pairing.
• Solid yellow: The MAO is connected to a device.
• Off (after a set time) even though the MAO is switched on: Deep sleep mode is active. This is designed to conserve battery power if, for example, the MAO has not been used for a long time. To exit deep sleep mode, switch the MAO off and then on again. The LED will flash again or turn solid yellow. (from version 1.0.5 dated 09/06/2026)

If the MAO is to be connected to another device, the existing connection must first be disconnected.

Charging LED

• Flashing red: The internal battery is charging.
• Solid red: The battery is fully charged, or the on/off switch next to the USB port is turned off preventing charging.
• LED off (with charging cable connected and device turned on): The battery is fully charged.
