Laser diode characteristics Wave length : 785 nm to 814 nm Maximum output : 1 190 µW(Emitting period : unlimited) Additional Laser Caution Transistors Q101 in PCB drive the laser diodes. When Q101 is shorted between their terminals, the laser diodes will radiate beam. If the top cover is removed with no disc loaded while such short-circuit is continued, the naked eyes may be exposed to the laser beam.
1. SERVICE PRECAUTIONS 1.1 SERVICE PRECAUTIONS 1. You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and should keep the safety during servicing by following the safety instructions described in this manual. 2. Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during power-on mode may damage the ICs inside the unit.

How to carry the mecha unit 1. Hold the designated points (shown with dashed lines) of the upper chassis and the front/rear bracket. 2. Be careful not to hold the solid line portions or the CRG mecha part or insert foreign substances, to prevent distortion. 3.
Page 29
How to remove the PU unit 1. Create an empty-clamp state according to “How to create empty clamp state (motor drive)”. 2. Hook the feeding screw biasing spring to a tentative hooking portion (Fig 2b). Be careful not to get injured by the spring edge.
8. EACH SETTING AND ADJUSTMENT 8.1 CD ADJUSTMENT 1) Cautions on adjustments 2) Test mode This mode is used to adjust the CD mechanism module. In this product the single voltage (3.3 V) is used for the regulator. The reference voltage is the REFO1 (1.65 V) To enter the test mode.
8.2 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.
8.3 PCL OUTPUT CONFIRMATION - PCL output With the TESTIN (22 pin) status of IC601 to be “H”, it is shifted to PCL Output Test mode after reset started. Check that square wave of 600.0 kHz is output from PCL (8 Pin) of IC601. If clock signal is out of this range, this resonator (X602) must be changed for a new one.
