Service manual

By a combination of automatic diagnostics and an interactive question/answer
procedure, ComPair will enable you to find most problems in a fast and effective way.
Beside fault finding, ComPair provides some additional features like:
• Emulation of the (European) Dealer Service Tool (DST).
• If both ComPair and SearchMan / Force (Electronic Service Manual) are
installed, all the schematics and the PWBs of the set are available by clicking on
the appropriate hyperlink.
Example: Measure the DC-voltage on capacitor C2568 (Schematic/Panel) at the
Monocarrier.
Click on the 'Panel' hyperlink to automatically show the PWB with a highlighted
capacitor C2568.
Click on the 'Schematic' hyperlink to automatically show the position of the highlighted
capacitor.
