1. Precautions Follow these safety, servicing and ESD precautions to prevent damage and protect against potential hazards such as electrical shock and X-rays. 1-1 Safety Precautions 1. Be sure that all of the built-in protective devices are replaced. 2. When reinstalling the chassis and its assemblies, be sure to restore all protective devices, including control knobs and compartment covers. 3.
Precautions 1-1 Safety Precautions (Continued) 7. Components, parts and wiring that appear to have overheated or that are otherwise damaged should be replaced with parts that meet the original specifications. Always determine the cause of damage or overheating, and correct any potential hazards 8. Observe the original lead dress, especially near the following areas: Antenna wiring, sharp edges, and especially the AC and high voltage power supplies.
Precautions 1-3 Precautions for Electrostatically Sensitive Devices (ESDs) 1. Some semiconductor ("solid state") devices are easily damaged by static electricity. Such components are called Electrostatically Sensitive Devices (ESDs). Examples include integrated circuits and some field-effect transistors. The following techniques will reduce the occurrence of component damage caused by static electricity. 5. Use only a grounded-tip soldering iron when soldering or unsoldering ESDs. 2.
Precautions 1-4 Special Precautions and Warning Labels for Laser Products (Continued) 1-4-1 Warnings 1. When servicing, do not approach the LASER exit with the eye too closely. In case it is necessary to confirm LASER beam emission, be sure to observe from a distance of more than 30 cm from the surface of the objective lens on the optical pick-up block. 2. Do not attempt to handle the objective lens when the DISC is not on the tray.

2. Notes on discs Disc Recording Format CD-R Discs • Some CD-R discs may not be playable depending on the disc recording device (CD-Recorder or PC) and the condition of the disc. • Use a 650MB/74 minute CD-R disc. Do not use CD-R disk over 700MB/80 minute as much as possible since it may not be played back. • Some CD-RW (Rewritable) media, may not be playable. • Only CD-Rs that are properly "closed" can be fully played.
3. Accessories Code no.
3. Product Functions 1. SPK connection Connecting the Loudspeakers Connect the connecting jacks (2) to the back of mini-compact system. Make sure the polarities (+and -) are correct. Left speaker wire should be connected to mark “L” of the unit back. Right speaker wire should be connected to mark “R” of the unit back.
2. Main Functios Loading and Changing Compact Discs The CD disc changer can contain up to three 12 cm or 8 cm compact discs without using an adapter. To replay the CD/MP3-CD This is a player that enables the playback of audio CD, CD-R, CD-RW and MP3-CD and does not possess the function that saves MP3 files. Never force the compact disc carrousel when opening and closing the compartment. Do not use CDs of irregular shapes like heart or octagon shapes. The performance of the player may be degraded.
Repeating One or All Tracks on the Compact Discs You can repeat indefinitely: A specific track on a compact disc. All tracks on the compact disc selected. All discs loaded in the carrousel 1 2 Function to skip through 10 tracks at a time Press the +10 button briefly while playing back a CD and MP3-CD. The track 10 tracks after the current one will then be played back. To repeat... Press CD REPEAT on the Remote Control or more times until...
3. New Functions Power Surround/Power Surround XT/Power Sound Function Mute Function You can turn the sound off temporarily on your system. Example: You wish to answer a telephone call. 1 2 Press MUTE. To switch the sound back on (at the same volume as before), press MUTE again or the VOLUME buttons. P.SURROUND TIMER ON/OFF DEMO/DIMMER SOUND MODE AI SLEEP PROGRAM/SET MEDLEY TUNER The Power Surround replaces conventional stereo sound with a wider and more true-to-life sound.
4. Adjustments Cassette Deck 1. To Adjust Tape Speed Notes MAIN PCB 1) Measuring tape: i) MTT-111 (or equivalent) (Tapes recorded with 3kHz) ii) MTT-5512 (or equivalent) 2) Connect the SPK OUT of the MAIN PCB to the frequency counter as in figure 1-5.
2. To Adjust PlayBack Level/REC Notes 1) Before the actual adjustment, clean the play/recording head. 2) Measuring tape : i) MTT-114N(or equivalent 10kHz AZIMUTH control) ii) MTT-5512 3) The cassette deck is connections as shown in figure 1-7. 1. Adjust Deck 1 Play Level Step 1 Item AZIMUTH Pre-Setup Condition SPK OUT (VTVM is connected to the scope) Pre-Setup After putting MTT114N into Deck 1 - Press FWD PLAY button. To Adjust - Turn the control screw to as shown in Figure 1-6.
