6.3 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT • Note : 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 mechanism module and is thus the best adjusted PU unit for the CD mechanism module.
6.4 ERROR MODE - Error Messages If a CD is not operative or stopped during operation due to an error, the error mode is turned on and cause(s) of the error is indicated with a corresponding number. This arrangement is intended at reducing nonsense calls from the users and also for facilitating trouble analysis and repair work in servicing.
6.5 BLUETOOTH TEST MODE - About Memory Clear When resetting the microprocessor, the memory is initialized except for the following four items. This enables user to avoid the task of registering phones and transfering phone directory again even after resetting system at the time of battery exchange, etc.

6.6 SYSTEM MICROCOMPUTER TEST PROGRAM - PCL Output In the normal operation mode (with the detachable panel installed, the ACC switched ON, the standby mode cancelled), shift the STEST IC601(Pin 86) terminal to H. The clock signal is output from the PCL1 terminal IC601(Pin 41). The frequency of the clock signal is 625.000 kHz that is one 32th of the fundamental frequency.
7. GENERAL INFORMATION 7.1 DIAGNOSIS 7.1.1 DISASSEMBLY Removing the Case (not shown) 1. Remove the Case. CD Mechanism Module Removing the CD Mechanism Module (Fig.1) Remove the four screws. Disconnect the connector and then remove the CD Mechanism Module. Fig.1 Removing the Cord Assy (Fig.2) Disconnect the Cord Assy by Jig GGF1539.
Page 79
When unplugging the cord assy, make sure to use jig GGF1539. If the antenna cable is directly unplugged without using jig GGF1539, you might damage your fingertip or fingernail. - How to Remove the Cord Assy When unplugging cord assy, hook the point of jig GGF1539 on the lid of cord assy and vertically draw out along with the engagement axis of connector.
