2 Product Safety Notice

Many electrical and mechanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a on the schematics and on the parts list...

The position of the switch (S601) for detecting loading state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch (S601) is not on CLMP terminal side (CLMP signal is OFF or high level.). Thus, the interlock will no longer function if the switch (S601) is deliberately set to CLMP terminal side (low level). The interlock also does not function in the test mode *. Laser diode oscillation will continue, if pin 1 of M51593FP (IC101) on the...

Danger Laser Radiation When Open Avoid Direct Exposure To Beam

(1) Check that CD is displayed on the FL display. If CD-R or CD-RW is displayed, press the STOP button repeatedly until CD is displayed. (2) Press the RECORD button. The LED for confirmation of LD emission will light in orange. (3) Press the REC MUTE button. The LED for confirmation of LD emission will light in red. The LD is emitting in this status. (4) Turn VR101 clockwise until the adjustment value to be reached is obtained. (5) Press the STOP button to shut off the LD.

Leakage Current Check

Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input output terminals, screw heads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA.
