Alignments & Adjustments
8. Alignments & Adjustments
Each CDR-module composed from CDRloader and
CDRmainboard has to be matched via SW filled
parameters.This adjustment processed in the factory is under
investigation to have it implemented into the COMPAIR tool. As
long as this adjustment is not possible to be executed in
secondline service workshop, the swop of modules and a
central repair has to be continued. Adjustment only has to be
done at replacement of CDM and concerned servo circuits.
Other repairs (audio signals, replacement of adapted Flash
roms etc) can be done without infringing the adjusted
components.
As soon as COMPAIR CDR is installed this chapter will be
adapted via a service information.
Flash Rom IC 7208 (MACE-ROM) is mounted on a socket and
can be replaced after lifting up the loader part above it. Flash
Rom IC 7703 (DASP-ROM) has to be soldered.
Take care for both ICs Firmware loaded components are
mounted.
In case a module is offered with SW versions 1.4 and 91.48, the
complete CDR-module should be replaced.
For SW versions 1.23 and 91.63, IC7703 and IC7208 have to
be replaced by the latest SW verions.
