No.21160 Oct. 2002

RX-8022PSL

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 circuitr y 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 fur ther 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 par ts 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 each exposed 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.).

0.15 F AC TYPE

1500 10W

AC VOLTMETER (Having 1000 ohms/volts, or more sensitivity)

Place this probe on each exposed metal part.

!

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 m ust 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 pr inted 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 method

Tuner section

1.Tuner range FM 87.5MHz~108.0MHz AM(MW) 531 kHz to 1 602 kHz (at 9 kHz intervals) 530 kHz to 1 600 kHz (at 10 kHz intervals)

Power amplifier section

Adjustment of idling current

Measurement location B2204-B2205(Lch) , B2213-2214(Rch) Adjustment part 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, after you turn off amplifier and internal temperature falls.

RX-8022PSL

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.

Pin 2 Micro-computer+5V Pin 3 Digital+5V Pin 4 Analog+5V Pin 5 +12V Pin 7 Tuner+9V

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

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-8022PSL

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.

While the working status is being displayed, the each item can be switched with the UP/DOWN key operation.

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.
