AVR520

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called

Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and

semiconductor "chip" components.

The following techniques should be used to help reduce the incidence of component damage caused by static electricity.

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on

your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,

which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to

prevent electrostatic charge build-up or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

harman/kardon

4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges

sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement

ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the

chassis or circuit assembly into which the device will be installed.

CAUTION :

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together

or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

Each precaution in this manual should be followed during servicing.

Components identified with the IEC symbol in the parts list are special significance to safety. When replacing a component identified with

, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the

parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably

insulated from the supply circuit before retuming the product to the customer.

AVR520

Before returning the unit to the user, perform the following safety checks :

1. Inspect all lead dress to make certain that

leads are not pinched or that hardware is not

lodged between the chassis and other metal

parts in the unit.

2. Be sure that any protective devices such as

nonmetallic control knobs, insulating fish-

papers, cabinet backs, adjustment and

compartment covers or shields, isolation

harman/kardon

resistor-capacity networks, mechanical

insulators, etc. Which were removed for the

servicing are properly re-installed.

3. Be sure that no shock hazard exists ; check for leakage

current usingSimpson Model 229 Leakage Tester, standard

equipment item No. 21641, RCA Model WT540A or use

alternate method as follows : Plug the power cord directly

Into a 120 volt AC receptacle (do not use an Isolation

Transformer for this test). Using two clip leads, connect a

1500 ohms,10watt Resistor paralleledby a 0.15uFcapacitor,in series withall exposed metalcabinet parts anda known earth ground,such

as a water pipe or conduit. Use a VTVM or VOM with 1000 ohms per volt, or higher sensitivity to measure the AC voltage drop across the

resistor. (See diagram) Move the resistor connection to each exposed metal part having a return path to the chassis (antenna, metal,

cabinet, screwheads, knobsand controlshafts, escutcheon, etc.) and measurethe ACvoltage dropacross the resistor. (This testshould be

performed withthe 0.35 volt RMS or more is excessiveand indicates apotential shock hazardwhich must be corrected before returning the

unit to the owner.

Processor Reset

In the rare case where the unit’s operation or the displays seem abnormal, the cause may involve the erratic operation of the system’s memory or microprocessor.

To correct this problem, first unplug the unit from the AC wall outlet and wait at least three minutes. After the pause, reconnect the AC power cord and check the unit’s operation. If the system still malfunctions, a system reset may clear the problem.

To clear the AVR 520’s entire system memory including tuner presets, output level settings,

delay times and speaker configuration data, first put the unit in Standby by pressing the System Power Control button 2. Next, press and hold the

Tone Mode 8 and the

FM Mode Selector ^ buttons for three

seconds.

The unit will turn on automatically and display the

RESET message in the Main

Information Display

Y. Note that once you have cleared the memory in this manner, it is necessary to reestablish all system configuration settings and tuner presets.

NOTE: Resetting the processor will erase any configuration settings you have made for

speakers, output levels, surround modes, digital input assignments as well as the tuner presets. After a reset the unit will be returned to the factory presets, and all settings for these items must be reentered.

If the system is still operating incorrectly, there may have been an electronic discharge or severe AC line interference that has corrupted the memory or microprocessor.

If these steps do not solve the problem, consult an authorized Harman Kardon service depot.
