ComPair
Introduction
ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics
products. ComPair is a further development of the (European) DST (special RC
transmitter for Service), which allows faster and more accurate diagnostics. ComPair
has three big advantages:
• ComPair helps you to quickly get an understanding how to repair the EM1.1U in
short time by guiding you systematically through the repair procedures.
• ComPair allows very detailed diagnostics (on I
2
C level) and is therefore capable
of accurately indicating problem areas. You do not have to know anything about I
2
C commands yourself because ComPair takes care of this.
• ComPair speeds up the repair time since it can automatically communicate with
the chassis (when the microprocessor is working) and all repair information is
directly available. When ComPair is installed together with the Force/ EM1.1U
electronic manual, schematics and PWBs are only a mouse-click away.
