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.
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 symbolin 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.
-4-
Before returning the unit to the user, perform the following safety checks :
1. lnspect 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
500
compartment covers or shields, isolation
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 using Simpson 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 paralleled by a 0.15uF capacitor, in series with all exposed metal cabinet parts and a 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, be
performed with the 0.35 volt RMS or more is excessive and indicates a potential shock hazard which must be corrected before returning the
unit to the owner.

Subject: Random Noise, Erratic Output in DTS Mode
In the event you receive an AVR300 or AVR500 receiver with the complaint “there is distortion, random
noise or gaps in the program material when in the DTS mode”, perform the following procedure:
REMOVAL AND MODIFICATION OF THE DSP BOARD
1) Remove the top cover, (14) Black Phillips screws.
2) Locate the DSP PC Board; Figure 1. Remove the two metal braces at the top of the unit. If necessary, cut
the cable ties attached to the braces to move any wires away from the area.
3) Pull the white 22 conductor ribbon cable at the rear of the DSP PC Board straight out of its receptacle.
4) Unplug the white 5 conductor molex cable at the top of the DSP PC Board.
5) Remove the (33) plated Phillips screws on the left side of the rear backplate; see Figure 2. Do not remove
any additional screws on the right side. If using a power tool, use care and minimum effort to avoid damaging
the various plastic receptacles.
6) Remove all three black plastic plugs that cover the optical inputs at the rear of the DSP PC Board.
7) Pull on the left side of the rear backplate, away from the receiver chassis; you should be able to pull it away
enough to allow the DSP PC Board to be pulled straight up and out of the receiver.
8) Proceed with the modifications on page 2.

harman/kardon Service Bulletin
Service bulletin # H/K2000-05 May 2000Warranty labor rate: MAJOR repair
To: All harman/kardon Service Centers
Models: AVR300, AVR500
Subject: Volume Level Changes
On early versions of the AVR300 or AVR500 the volume level may change by itself, or when the volume knob
is tapped. This may happen on an occasional random basis and depends on where the volume control knob is
positioned after a volume adjustment. During a running production change, new volume encoders were
installed.
In the event you receive an AVR300 or AVR500 with the complaint “The volume on my receiver
changes by itself”, perform the following procedure:
REPLACE VR901 VOLUME ENCODER
1) Remove the top cover, (14) Black Phillips screws.
2) Remove the (11) Black Phillips screws holding the plastic front panel to the chassis.
3) Remove the single Phillips screw on both right & left side of the chassis with a dual black ground wire.
4) Remove the volume, bass, treble and balance knobs by pulling them straight off.
5) Remove the single nut holding the volume encoder to the front panel.
6) Pull the loaded front panel off the chassis; cut any plastic cable ties necessary to fully disengage it
7) Lift and set the receiver on its right side for the remainder of the procedure.
8) Remove molex connector CN983 at the power switch; see Figure 1.
9) Pull the front panel as far away as the remaining connecting wires will allow.
10) Unsolder the connections at the rear of the front PCB to the volume encoder.
11) Using a “stubby” Phillips screwdriver, remove the (19) Black Phillips screws holding the front PCB to the
front panel; two plated screws at the rear of the headphone jack also must be removed.
12) Pull the front PCB away from the front panel.
13) Remove and replace the volume encoder with h/k part# J32612050102; resolder the new encoder in place.
14) Replace the front PCB and reassemble the receiver in reverse order, following the instructions above.
Replace all cable ties that were cut, and reattach any connectors that were unplugged. Make sure the two
ground wires on both sides of the receiver are reattached.
15) Power up receiver, and test volume control to assure it no longer changes settings by itself, or when the
volume knob is tapped.
