	When inspecting an SR-D print, it is advisable to occasionally look at the SR-D soundtrack with a loupe for any thick base or emulsion scratches. If there is excessive wear on the SR-D track, you should keep a close eye on the track during playback and watch for dropouts. If the SR-D track is constantly failing (reading "F" on the processor) because the signal quality is too poor, the processor will revert to Dolby SR. The change in sound quality from SRD to SR is very apparent, so if the film is constantly switching between SRD and SR it is preferable to switch the sound format to SR and leave it in that format.
