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.
SAFETY PRECAUTIONS
The following check should be performed for the continued
protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a leakage current tester
between the earth ground and all exposed metal parts of the
appliance (input/output terminals, screwheads, metal
overlays, control shaft, etc.). Plug the AC line cord of the
appliance directly into a 120V AC 60Hz outlet and turn the
AC power switch on. Any current measured must not exceed
o.5mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A
POTENTIAL SHOCK HAZARD AND MUST BE
CORRECTED BEFORE RETURNING THE APPLIANCE
TO THE CUSTOMER.

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.
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.

Service bulletin # H/K2003-10 December 2003
To: All harman/kardon Service Centers
Models: AVR130, AVR230, AVR330, HK3380, HK3480
Subject: Volume Level Changes
On early versions of the AVR130,AVR230,AVR330,HK3380,HK3480, when the volume control is turned, the
volume level and display may be erratic, and not track accurately, or the level may progress in an unintended
direction. This may happen on a 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 AVR model listed above with the complaint “The volume control on my
receiver does not track accurately when turned”, perform the following procedure:
REPLACE VR74 (AVR130/230/330) or VR81 (HK3380/3480) VOLUME ENCODER
Note: It is import ant that the various screws do not get m ixed up and insert ed in other locat ions upon reassembly. Mak e
note or label eac h r emov ed screw set; keep them apart from ot her scr ew sets.
1) Remove the top cover, (13) Phillips screws.
2) Remove the volume, bass, treble and balance knobs by pulling them straight out and off. If a tool is
necessary for removal of the smaller knobs, make sure the jaws are insulated to avoid knob damage.
3) Remove the (10) Phillips screws holding the front panel ass’y to the chassis: (6) at the bottom and (4) at
the sides.
4) Cut all plastic cable ties that would prevent you detaching the front panel ass’y from the chassis. Draw a
diagram if necessary, for a location reminder, to aid reassembly.
5) Unplug connector CN15 (6 cond) or CN89 (7 cond) at the left side of the unit. See below.
6) Remove single ground screw at the left side of the unit, near CN15 or CN89. (Black wire)
7) Unplug connector CN72 (32 cond) or CN81 (20 cond) on the DSP PCB, coming from the top of the front
panel ass’y. See below.
8) There should now be enough slack in the connecting cables to lift and detach the front panel ass’y from
the chassis. Pull the front panel as far away as the remaining connecting wires will allow, enough to tilt
and gain access to the rear of the Tone/Volume PCB. See illustrat ion Page 2.
9) Remove the (10) screws or (9) screws holding the Tone/Volume PCB to the front panel.
10) Detach and pull back the PCB; unplug top connector CN84 (7 cond) or CN83 (4 cond) if necessary.
11) Remove and replace VR74 or VR81 (5 soldered pads) with hk part# HSR2A029Z.
12) Reassemble in reverse order, taking care to replace all connectors, cable ties, and ground screw.
13) Power up receiver, and test volume control to assure setting no longer changes settings by itself, or when
the volume knob is tapped.
