Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The ComPair II interface box is connected to the PC via an
USB cable. For the TV chassis, the ComPair interface box and

problem of the defective television, by a combination of
automatic diagnostics and an interactive question/answer
procedure.
