USER INTERFACE
The user interface is controlled by two buttons and
the response is displayed by the LCD. Pressing both
buttons at the same time for 6 seconds (this delay
can be changed in firmware settings) will unlock the
device displaying the current volume settings. Once
unlocked, the volume can be increased by pushing
the button pointing upwards, or decreased by the
button pointing downwards.
If the buttons are not pressed for 30 seconds (this
delay is also settable in the firmware) then the device
will return back to its normal state and display the
word “Active”. At this point the new volume setting is
written back to the EEPROM and will be the default
volume.
Note that if the volume is set, and the device is then
powered down before it has returned to its normal
state, then at the next power up it will revert to the
previous volume state, not the one last set.
