This design of this product contains special hardware and many circuits and components specially for safety purposes. For continued protection, no changes should be made to the original design unless authorized in writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Services should be performed by qualified personnel only. 2. Alterations of the design or circuitry of the product should not be made. Any design alterations of the product should not be made. Any design alterations or additions will void the manufacturers warranty and will further relieve the manufacture of responsibility for personal injury or property damage resulting therefrom. 3. Many electrical and mechanical parts in the products have special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in the Parts List of Service Manual. Electrical components having such features are identified by shading on the schematics and by ( ) on the Parts List in the Service Manual. The use of a substitute replacement which does not have the same safety characteristics as the recommended replacement parts shown in the Parts List of Service Manual may create shock, fire, or other hazards. 4. The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the like to be separated from live parts, high temperature parts, moving parts and/or sharp edges for the prevention of electric shock and fire hazard. When service is required, the original lead routing and dress should be observed, and it should be confirmed that they have been returned to normal, after re-assembling. 5. Leakage currnet check (Electrical shock hazard testing) After re-assembling the product, always perform an isolation check on the exposed metal parts of the product (antenna terminals, knobs, metal cabinet, screw heads, headphone jack, control shafts, etc.) to be sure the product is safe to operate without danger of electrical shock. Do not use a line isolation transformer during this check. Plug the AC line cord directly into the AC outlet. Using a Leakage Current Tester, measure the leakage current from each exposed metal parts of the cabinet , particularly any exposed metal part having a return path to the chassis, to a known good earth ground. Any leakage current must not exceed 0.5mA AC (r.m.s.) Alternate check method Plug the AC line cord directly into the AC outlet. Use an AC voltmeter having, 1,000 ohms per volt or more sensitivity in the following manner. Connect a 1,500 10W resistor paralleled by a 0.15 F AC-type capacitor between an exposed metal part and a known good earth ground. Measure the AC voltage across the resistor with the AC voltmeter. Move the resistor connection to eachexposed metal part, particularly any exposed metal part having a return path to the chassis, and meausre the AC voltage across the resistor. Now, reverse the plug in the AC outlet and repeat each measurement. voltage measured Any must not exceed 0.75 V AC (r.m.s.). This corresponds to 0.5 mA AC (r.m.s.). Warning 1. This equipment has been designed and manufactured to meet international safety standards. 2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained. 3. Repairs must be made in accordance with the relevant safety standards. 4. It is essential that safety critical components are replaced by approved parts. 5. If mains voltage selector is provided, check setting for local voltage. Good earth ground Place this probe on each exposed metal part. AC VOLTMETER (Having 1000 ohms/volts, or more sensitivity) 1500 10W 0.15 F AC TYPE !CAUTION Burrs formed during molding may be left over on some parts of the chassis. Therefore, pay attention to such burrs in the case of preforming repair of this system.

Take care to prevent this when performing repairs. 1.1. Grounding to prevent damage by static electricity Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as DVD players. Be careful to use proper grounding in the area where repairs are being performed. 1.1.1. Ground the workbench 1. Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the traverse unit (optical pickup) on it. 1.1.2. Ground yourself 1. Use an anti-static wrist strap to release any static electricity built up in your body. 1.1.3. Handling the optical pickup 1. In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical pickup are shorted. After replacement, return the shorted parts to their original condition. (Refer to the text.) 2. Do not use a tester to check the condition of the laser diode in the optical pickup. The testers internal power source can easily destroy the laser diode. 1.2. Handling the traverse unit (optical pickup) 1. Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit. 2. Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a time when attaching it to the connector. 3. Handle the flexible cable carefully as it may break when subjected to strong force. 4. It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it Conductive material (conductive sheet) or iron plate (caption) Anti-static wrist strap 1-5 UX-G6/FS-G6 When this model is repaired, a part of unit of UX-G6/FS-G6 is necessary. A necessary unit is described to rear panel. Please keep the unit from the customer together when you repair this model.

AM loop antenna (1) FM antenna (1) Remote control (1) Batteries (2) Speaker cords (2) External wire (1) If any is missing, consult your dealer immediately. Putting the Batteries into the Remote Control Insert the batteries R6P (SUM-3)/AA (15F) into the remote control, by matching the polarity (+ and ) on the batteries with the + and markings on the battery compartment. When the remote control can no longer operate the units, replace both batteries at the same time. DO NOT use an old battery together with a new one. DO NOT use different types of batteries together. DO NOT expose batteries to heat or flame. DO NOT leave the batteries in the battery compartment when you are not going to use the remote control for an extended period of time. Otherwise, it will be damaged from battery leakage. Connecting the System Control Cables and the External Wire UX-G6 micro component system consists of three units, AX-UXG6 Stereo Amplifier, XT-UXG6 Compact Disc/ Tuner, TD-UXG6 Cassette Deck, and SP-UXG6 Speaker System. You can easily connect these units using the system control cables equipped on the rear panel of the units. To prevent malfunction, connect the external wire as illustrated. DO NOT change vertical stacking order of the units as illustrated to avoid heat buildup. To connect the cables, press the middle of the connector body until it clicks into the connector on the rear panel. To disconnect, if needed, pull the connector out pushing both sides of the connector body. Never pull out the cables themselves. When connecting the system control cables to the connectors Make sure to connect the cable to the connector having the same name such as “FROM CONNECTOR-A” and “TO CONNECTOR-A.” Getting Started To connect To disconnect 1 2 3 R6P(SUM-3)/AA(15F) AX-UXG6 TD-UXG6 FROM CONNECTOR-A TO CONNECTOR-A FROM CONNECTOR-B TO CONNECTOR-B External wire (supplied) XT-UXG61 2 3 VOLTAGE SELECTOR 1-9 UX-G6/FS-G6 7 English Connecting Antennas Supplied FM antenna 1Attach the FM antenna to the FM 75 COAXIAL terminal on the rear panel of XT-UXG6. 2Extend the FM antenna. 3Fasten it up in the position which gives you the best reception. About the supplied FM antenna The FM antenna supplied with this unit can only be used as temporary measure. If reception is poor, you can connect an outdoor FM antenna. To connect an outdoor FM antenna Before connecting it, disconnect the supplied FM antenna. Connecting MD Recorder XM-G6 You can also connect the MD recorder XM-G6 (not supplied), specifically designed for UX-G6. This unit will complete UX-G6 micro component system. When you connect and use this unit, refer to the Instructions supplied with it for details.
