    DEH-P645R,P545R,P544R,P443R 6.3 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT • Note : Unlike previous CD mechanism modules the grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mechanism module is adjusted on the production line to match the CD mecha- nism module and is thus the best adjusted PU unit for the CD mechanism module.

    DEH-P645R,P545R,P544R,P443R 7.2.2 TEST MODE - Error Number Indication The system enters error mode to display the cause of error with a number when the system cannot operate CD or stops operation because of an error. The purpose of this measure is to reduce frequency of calls from users asking help for problems that are caused by incorrect operation by user, as well as to assist analysis and repair in servicing.

After setup, the system dis- plays the cause and time (absolute time) of an error if focus search is improper, spindle lock is removed, subcode cannot be read, or sound is skipped.
