SAFETY INFORMATION LABEL CHECK (for YPWXJ type) Additional Laser Caution 1.Laser Interlock Mechanism The position of the switch (S9501) for detecting loading state is detected by the syst

5、em microprocessor, and the design prevents laser diode oscillation when the switch (S9501) is pressed physically. Thus, the interlock will no longer function if the switch (S9501) is released physically and deliberatery. The interlock also does not function in the test mode . Laser diode oscillation

CONTRAST OF MISCELLANEOUS PARTS Parts marked by NSP are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of th

Reference Nos. indicate the pages and Nos. in the service manual for the base model. NOTES: When ordering resistors, first convert resistance values into cod

10、e form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%).
