There is no hazardous invisible laser radiation during operation because invisible laser radiation emitted inside of this product is completely confined in the protective housings. The label required in this regulation is shown 1. OCAUTION USE OF CONTROLS OR ADJUSTMENT OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. CD 1For U.S.A. Optical pickup: Type: LTOH96MK or GH5C105A1APK Manufacturer : SHARP Corporation Laser output : Less than 0.5 mW on the objective lens Wavelength: 770-795 nm Voltage Conversion (General export models only) Be sure to remove the power cord from the AC outlet before repositioning the voltage converter switch. 1. Locate the voltage selector on the rear panel. 2. Using a flat-bladed screwdriver, set to the appropriate 230V or 120V position according to your area.

Connect the frequency counter to the CD OUT. 2. Turn on a CD PITCH CONTROL switch at the stop mode. 3. Play the track 2 (1kHz, 0dB) of the MCD-111. 4. Set a CD PITCH CONTROL knob to a center, and adjust R811 of CONTROL PCB so that the output becomes 1kHz. 5. When the CD PITCH CONTROL knob is rotated to the side, make sure the frequency becomes 880 Hz or lower, and make sure it becomes 1,120 Hz or higher when the knob is rotated to the side. 3-1-2 Output level check 1. Connect the AC voltmeter to the CD OUT. 2. Play the track 2 (1kHz, 0dB) of the MCD-111, and check the output level. Specification: 2.00.5Vrms 3-1-3 Distortion check 1. Connect the distortion meter to the CD OUT. 2. Play the track 2 (1kHz, 0dB) of the MCD-111, and check the distortion.
