Prism Sound ADA-8 Multi-channel A/D D/A Converter Operation Manual - Revision 1.00
In these cases, warnings are generated. Warnings are indicated by a flashing LED, and
possibly the solid illumination of an additional LED. For example, in the case of an
unconnected external reference sync, local sync will be automatically substituted and this
state will be shown by the 'Local' LED being lit and the LED of the intended external sync
being flashed.
In general, solidly lit LEDs indicate what is actually happening, and flashing LEDs indicate
what has been requested but cannot be implemented.
If any warnings are active, a row of flashing exclamation marks are shown at the right-hand
side of the LCD display when it is in the default 'level' display mode ('!!!→'). Pressing the
right 'Select/Change' key ('→') enters the Warnings screen, where all the current warnings are
flashed in turn on the bottom line of the LCD. To return to the normal 'Level' display, press
the left 'Select/Change' key ('←').
