IR Code Converter 8089017

1st November 2010

This unit would not work with a Beomaster 5000 because 2D1 (1N4148) was short circuit and 2TR12 (BC548B) was leaky. Replacements restored normal operation but the reason for the failures remains unclear. Note that the table of switch positions shown on some editions of the circuit diagram is incorrect, those in the main installation manual give the right settings.
