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
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.

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.
Reading should
not be above
0.5mA

• Amplifier is in protection mode • Contact your local Harman Kardon service depot
due to internal problems
• Stereo or Mono program material• With (analog or digital) Dolby surround modes, the surround
decoder may not create rear-channel
information from non-encoded programs
• Speakers not properly connected• Check speaker-wire connections or use test tone
to verify connections (see page 20)
Unit does not respond to • Weak batteries in remote• Change remote batteries
remote commands• Wrong device selected• Press the AVR selector
• Remote sensorEis obscured• Make certain front-panel sensor is visible to remote or
connect remote sensor
Intermittent buzzing in tuner• Local interference• Move unit or antenna away from computers, fluorescent lights,
motors or other electrical appliances
Letters flash in the Channel Indicator• Digital audio feed paused• Resume play for DVD
Display and Digital Audio stops• Check that Digital Signal is fed to the Digital Input selected
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’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 SystemPower Control button
the Surround Mode Button
The unit will turn on automatically. Note that
once you have cleared the memory in this manner,
it is necessary to re-establish all system
configuration settings and tuner presets.
1
. Next, press and hold
6
for 5 seconds.
5
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.

The LM1117 is a low power positive-voltage regulator designed to meet 1A output current and comply
with SCSI-II specifications with a fixed output voltage of 2.85V. This device is an excellent choice for use
in battery-powered applications, as active terminators for the SCSI bus, and portable computers.
The LM1117 features very low quiescent current and very
low dropout voltage of 700mV at a full load and
lower as output current decreases. LM1117 is available as an adjustable or fixed 1.5V, 1.8V, 2.5V, 2.85V,
3.0V, 3.3V, and 5.0V output voltages.
The LM1117 is offered in a 3-pin surface mount package SOT-223 & TO-263. The output capacitor of
10㎌ or larger is needed for output stability of LM1117 as required by most of the other regulator circuits.

bit (RW) (as described in Table 3.), terminated by an acknowledge bit.
When writing data to the memory, the dev ice inserts an acknowled ge bit during the 9

following the bus master’s 8-bit transmission.
When data is read by the bus master, the bus
master acknowledge s the rec eipt o f the d ata by te

a Stop condition after an Ack for Write, and after a

In order to prevent data corruption and inadvertent
Write operations during Power-up, a Power On
Reset (POR) circuit is included . At Power-up, the
internal reset i s he ld a cti ve unti l V
has reached

the Power On Reset (POR) threshold voltage, and
all operations are disabled – the device will not respond to any command. In the sam e way, when
V
drops from the operat ing voltage, below the
CC
Power On Reset (PO R) threshold voltage, a ll operations are disa bled and the device will not respond to any command.
A stable and valid V

Table 10.) must be applied before applying any
logic signal.

Description
The MC78XX/LM78XX/MC78XXA series of three
terminal positive regulators are available in the
TO-220/D-PAK package and with several fixed output
voltages, making them useful in a wide range of
applications. Each type employs internal current limiting,
thermal shut down and safe operating area protection,
making it essentially indestructible. If adequate heat sinking
is provided, they can deliver over 1A output current.
Although designed primarily as fixed voltage regulators,
these devices can be used with external components to
obtain adjustable voltages and currents.
The NJM2595 is a 5-input 3-output video switch. Its switches
select one from five signals received from VTR,TV,DVD,
TV-GAME and others.
The NJM2595 is designed for audio items, such as AV amplifier
and others.
