CD-C449W/K449W SAFETY PRECAUTION FOR SERVICE MANUAL WARNINGS THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. THEREFORE IT IS IMPORTANT THAT THE FOLLOWING PRECAUTIONS ARE OBSERVED DURING SERVICING TO PROTECT YOUR EYES AGAINST EXPOSURE TO THE LASER BEAM. 1-WHEN THE CABINET IS REMOVED, THE POWER IS TURNED ON WITDOUT A COMPACT DISC IN POSITION AND THE PICK-UP IS ON THE OUTER EDGE THE LASER WILL LIGHT FOR SEVERAL SECONDS TO DETECT A DISC. DO NOT LOOK INTO THE PICK-UP LENS. 2-THE LASER POWER OUTPUT OF THE PICK-UP UNIT AND REPLACEMENT SERVICE PARTS ARE ALL FACTORY PRE-SET BEFORE SHIPMENT. DO NOT ATTEMPT TO RE-ADJUST THE LASER PICK-UP UNIT DURING REPLACEMENT OR SERVICING. 3-UNDER NO CIRCUMSTANCES STARE INTO THE PICK-UP LENS AT ANY TIME. 4-CAUTION-USE OF CONTROLS OR ADJUSTMENTS, OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. CAUTION Laser Diode Properties Material: GaAIAs Wavelength: 780 nm Emission Duration: continuous Laser Output: max. 0.6 mW ● This Mini Component System is classified as a CLASS 1 LASER product. ● The CLASS 1 LASER PRODUCT label is located on the rear cover. ● Use of controls, adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. As the laser beam used in this compact disc player is harmful to the eyes, do not attempt to disassemble the cabinet. Refer servicing to qualified personnel only.

Adjust the minutes by turning the jog dial. Press the MEMORY button. ● The clock starts operating from "0" seconds. (Seconds are not displayed.) Note: ● In the event of a power failure or when the AC power lead is disconnected, the clock display will go out. When the AC power supply is restored, the clock display will flash on and off to indicate the time when the power failure occurred or when the AC power lead was disconnected. If this happens, follow the procedure below to change the clock time. To change the clock time: When the unit is in the stand-by mode: ① Press the MEMORY button. ② Perform steps 6 - 9 above. When the unit is on: 9 ① Press the CLOCK button. ② Within 5 seconds, press the MEMORY button. ③ Perform steps 6 - 9 above. To see the time display: Press the CLOCK button. ● The time display will appear for about 5 seconds. To change the time display mode: ① Perform steps 1 - 2 in the section "RESETTING THE MICROCOMPUTER", on page 28. ② Perform steps 1 - 9 above. –7– –8– ON/STAND-BY FLAT RESETTING THE MICROCOMPUTER 50/9 100/10 FM/MW (kHz) SPAN SELECTOR Press the ON/STAND-BY button whilst holding down the button and the FLAT button. Set the SPAN SELECTOR switch to "50/9" for 9 kHz MW interval (50 kHz FM interval), and "100/10" for 10 kHz MW interval (100 kHz FM interval). Press the ON/STAND-BY button to enter the stand-by mode. Press the ON/STAND-BY button whilst holding down the button and the FLAT button. Press the ON/STAND-BY button to enter the stand-by mode. Caution: ● The operation explained above will erase all data stored in memory including clock and timer settings, and tuner and CD presets. 1 2 Reset the microcomputer under the following conditions: ● To erase all of the stored memory contents (clock and timer settings, and tuner and CD presets). ● If the display is not correct. ● If the operation is not correct. Caution: ● The operation explained above will erase all data stored in memory including clock and timer settings, and tuner and CD presets. 3 1 2 To change the tuning zone: Before using the unit, set the SPAN SELECTOR switch (on the rear panel) to MW tuning interval (span) of your area. The International Telecommunication Union (ITU) has established that member countries should maintain either a 10 kHz or a 9 kHz interval between broadcasting frequencies of any MW station. The illustration shows the 9 kHz interval zones (regions 1 and 3), and the 10 kHz interval zone (region 2). ■ FM/MW interval (span) (Continued) + - 15 0.2 m - 6 m (8" - 20') + 15 ● 2 "AA" size batteries (UM/SUM3, R6, HP-7 or similar) ● Keep the remote control away from moisture, excessive heat, shock, and vibrations. ● Periodically clean the transmitter LED on the remote control and the sensor on the main unit with a soft cloth. ● Exposing the sensor on the main unit to strong light may interfere with operation. Change the lighting or the direction of the unit. Notes concerning use: ● Replace the batteries if the operating distance is reduced or if the operation becomes erratic. Caution: Do not use rechargeable batteries (nickel-cadmium battery, etc.). ● Insert the batteries according to the direction indicated in the battery compartment. ● Replace all old batteries with new ones at the same time. ● Do not mix old and new batteries. ● Remove the batteries if they are weak or if the unit will not be used for long periods of time. This will prevent potential damage due to battery leakage. Precautions for battery use: ● When inserting or removing the batteries, push them towards the battery terminal. ● Installing the batteries incorrectly may cause the unit to malfunction. ■ Remote control CD-C449W/K449W CD-C449W/K449W DISASSEMBLY Caution on Disassembly Follow the below-mentioned notes when disassembling the unit and reassembling it, to keep it safe and ensure excellent performance: 1. Take cassette tape and compact disc out of the unit. 2. Be sure to remove the power supply plug from the wall outlet before starting to disassemble the unit. 3. Take off nylon bands or wire holders where they need to be removed when disassembling the unit. After servicing the unit, be sure to rearrange the leads where they were before disassembling. 4. Take suffcient care on static electricity of integrated circuits and other circuits when servicing.

It produces real depth and localization of the sound image which cannot be accomplished by ordinary stereo. SRS only requires two speakers. SRS (●) 3D surround effects: Ordinary stereo sound ● Live performance atmosphere (Simulates a live concert atmosphere) ● The localization of various musical sources is quite clear. (The positions of the musical instruments and singers are very clear.) ● Reproduction of depth (Sounds from the front and back of an orchestra can be identified easily.) ● Expansion of the sound field (The sound image is spread out over a wide area.) Selecting the 3D surround mode: When the sound source is in stereo, you can select from any of 5 different 3D surround effect. Listening area (Listening range with good stereo fidelity) 3D SURROUND 1 2 Select any desired audio source and begin playback. To hear the 3D surround effect, press the SRS MODE button. ● "SRS (●)" will appear. When the SRS MODE button is pressed, the current mode setting will be displayed. To change to a different mode, press the SRS MODE button repeatedly. ● "PASS" will not be displayed in remote control operation. MODE-1 Wide listening area (Stereo music can be heard anywhere in the room.) SURROUND MODE MODE-1 MODE-2 MODE-2 MODE-3 MODE-4 MODE-5 PASS Notes: ● The 3D SURROUND effect will not work on a monaural sound source. ● When the 3D surround mode is being used, the equalizer will be set to FLAT. To cancel the 3D surround effect: Effect from each mode You will enjoy a sound image that produces an intimate sound field. (as in a medium-size hall) (Main unit operation) Press the SRS MODE button repeatedly to select "PASS". (Remote control operation) Press the PASS button. This setting gives you a maximum sound field as music comes out beyond the speakers. (as in a large, domed arena) MODE-3 This setting is great for live recording and vocal music. MODE-4 You will hear more vocals in an intimate sound field. (as at a live music performance) MODE-5 This setting greatly increases the amount of vocals or centre sounds in a recording.

Besides, the one with “Fusible” is a fuse type. • Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used.
