Mute Quick press: Sets the audio output (speakers and head-
phones) to a preset (typically low) level configured by the
installer. Returns to the previous volume when pressed
again. If the Power button is used to switch between
standby and on, the Mute status is retained.
Long press: Pressing the button for more than 400 ms
causes the speakers (but not headphones) to mute. This
state is reversed by another long press.
This action may vary depending on how the installer has
configured the system.
