SAFETY INFORMATION LITHIUM BATTERY NOTICE LABEL CHECK NVXK typeMYXK type IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON. LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 5 mW WAVELENGTH: 780 Ð 785 nm 1. Laser Interlock Mechanism The loading position detect switch (in CD mechanism assembly) is set to "CLMP ON(CD CLOSE)" (ON:low level,OFF:high level) position, the system control IC(IC5501) get the "CLMP" signal, and hand the laser "LDON" signal to IC1101. Then a laser diode can be lighted except when the level of signal CLMP is low. The interlock also does not function in the test mode*. Laser diode oscillation will continue, if pin 1 of CXA1821M (IC1101) on the RF UNIT is connected to GND, or pin 19 is connected to low level (ON), or else the terminals of Q1101 are shorted to each other (fault condition). 2. When the cover is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 1 laser beam. * : Refer to page 42. Additional Laser Caution
