PMC PMC6 User Manual page 39

During the firmware update process the speaker's illuminated logo will flash
white/blue or white/green. Once the update is complete the speaker will
be re-booted and the web-interface will refresh. This process can take up
to 60 seconds, and during this time the SoundAlign interface must not be
refreshed, or the speaker power cycled or disconnected from the network.
Logo Brightness
This control adjusts the brightness of the PMC logo on the front of the speaker.
At the minimum (10%) setting the logo will only glow when activated by the
driver protection system or to indicate user interaction with the SoundAlign
web interface.
Support
A link to the SoundAlign FAQ and support page can be found at the top
right-hand corner of the main window.
Mobile Devices
Due to the small screen size of mobile phones the full grid-matrix of controls
and the EQ graph are not displayed when accessing SoundAlign from these
devices. Instead, these controls can be accessed through a series of sliders
and toggle buttons in the Control window.
If multiple speakers are selected the controls display the settings of the
'Current' speaker, but any changes made in this window will affect all
selected speakers.
