Jeremy, it's not that you can't watch TV while printing if you put ruby lith over the screen. The real problem is the distraction of the flashing and changing light patterns you get while trying to print or evaluate negatives etc. I don't know whether or not they program with flashing from light to dark on purpose but I wouldn't put it past them.

Of course you can't load film with the thing on but after loading into a tank it is nice company for processing.
