1. 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 manufacturer`s 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. AC VOLTMETER Measure the AC voltage across the resistor with the AC (Having 1000 ohms/volts, voltmeter. or more sensitivity) Move the resistor connection to each exposed metal part, particularly any exposed metal part having a return path to 0.15 F AC TYPE the chassis, and meausre the AC voltage across the resistor. Place this Now, reverse the plug in the AC outlet and repeat each probe on measurement. Voltage measured any must not exceed 0.75 V each exposed AC (r.m.s.). This corresponds to 0.5 mA AC (r.m.s.). 1500 10W metal part.
Good earth ground
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.
! 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.
In regard with component parts appearing on the silk-screen printed side (parts side) of the PWB diagrams, the parts that are printed over with black such as the resistor ( ), diode ( ) and ICP ( ) or identified by the " " mark nearby are critical for safety. (This regulation does not correspond to J and C version.)

Adjustment of idling current Measurement location Adjustment part B2204-B2205(Lch) , B2213-2214(Rch) VR787(Lch) , VR788(Rch)
Attention This adjustment does not obtain a correct adjustment value immediately after the amplifier is used (state that an internal temperature has risen). Please adjust immediately after using the amplifier after turning off the power supply of the amplifier and falling an internal temperature. 1.Set the volume control to minimum during this adjustment.(No signal & No load) 2.Set the surround mode OFF. 2.Turn VR787 and VR788 fully counterclockwise to warm up before adjustment. If the heat sink is already warm from previous use the correct adjustment can not be made. 3.For L-ch,connect a DC voltmeter between B2204 and B2205 (Lch) And,connect it between B2213 and B2214(Rch). 4.30 minutes later after power on, adjust VR787 for L-ch, or VR788 for R-ch so that the DC voltmeter value has 1mV~10mV. * It is not abnormal though the idling current might not become 0mA even if it is finished to turn variable resistance (VR787,VR788) in the direction of counterclockwise.

Self-diagnose function
1. Detection of abnormal power supply and voltage
When the power is turned ON, if an abnormality is detected during the signal input at the A/D port (IC901, pin 2-5, 7) for one second continuously, the status will become STANDBY mode immediately. When the power is turned ON again, detection of abnormal power supply and voltage will not be carried out during the first 4 seconds. Given below is a list of threshold values at the detection of abnormalities. At abnormal state (Low voltage) Analog value 0 - 2.2V Analog value 0 - 2.2V Analog value 0 - 2.2V Analog value 0 - 2.2V Analog value 0 - 2.2V At normal state Analog value 2.2 - 2.8V Analog value 2.2 - 2.8V Analog value 2.2 - 2.8V Analog value 2.2 - 2.8V Analog value 2.2 - 2.8V At abnormal state (High voltage) Analog value 2.8 - 5.0V Analog value 2.8 - 5.0V Analog value 2.8 - 5.0V Analog value 2.8 - 5.0V Analog value 2.8 - 5.0V

2. Initial setting on ship
To gain the initial setting on ship, put the power plug in the socket while pressing DOWN key and UP key together simultaneously, then turn the power ON.
3. Test mode
To enter the test mode, put the power plug in the socket while pressing EFFECT key and UP key together simultaneously, then turn the power ON. Workings of test mode: All FLs are turned ON for 3 seconds. (the FLs, which are divided in two groups, are turned ON alternatively) A Faster volume UP/DOWN operation can be achieved with the remote controller. When the power is turned OFF, the test mode will be released. The FL display returns to normal after the three seconds. Then the STANDBY LED is turned ON (flashing ON and OFF for each one second) to show the present status being a test mode.

RX-8012PSL 4. Self-diagnose
To enter the self-diagnose mode, put the power plug in the socket while pressing SETTING key and UP key together simultaneously, then turn the power ON. With the UP/DOWN key operation, DSP microcomputer, ROM No.of system microcomputer as well as working status of DSP can be displayed for five seconds. While the working status is being displayed, the followings items can be switched with the UP/DOWN key operation. VERSION of system microcomputer Local microcomputer CH0 Local microcomputer CH01 Local microcomputer CH2 Local microcomputer CH3 Local microcomputer CH4
When the power is turned OFF, the self-diagnose mode will be released. During the self-diagnose mode, the STANDBY LED is turned ON . (flashing ON for one second then OFF for three seconds) FL transient display will be carried out as follows. When the transient display is not carried out, normal display/workings are carried out.
