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.

multipurpose, indicating either the speaker type selected for each
channel or the incoming data-signal configuration. The left, center,
right, right surround and left surround speaker indicators are composed
of three boxes, while the subwoofer is a single box. The center box lights
when a “Small” speaker is selected, and the two outer boxes light when
“Large” speakers are selected. When none of the boxes are lit for the
center, surround or subwoofer channels, no speaker has been selected
for that position. (See page 20 for more information on configuring
speakers.) The letters inside each of the center boxes display active
input channels. For standard analog inputs, only the L and R will light,
indicating a stereo input. When a digital source is playing, the indicators
will light to display the channels being received at the digital input.
When the letters flash, the digital input has been interrupted.

With the AVR ’s powerful processor, you may connect up to three
HDMI-equipped source devices to the HDMI inputs using a single-cable
connection, while benefiting from superior digital audio and video
performance. However, if your video display is not HDMI-compatible, you
will need to connect the source device to one of the other source inputs,
selecting a coaxial or optical digital audio input and analog video input.
See the Connections and Installation sections for more information.
If your video display has an HDMI input, but some of your sources have only
analog video outputs, you may still rely on just the HDMI video connection
to your display; the AVR will automatically transcode analog video signals
to the HDMI format.

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 System Power Control button
hold the OK button
The unit will turn on automatically and show the word RESET in the Display
for a few seconds. Then it reverts to normal ON status. Note that once you
have cleared the memory in this manner, it is necessary to re- establish 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.

When writing data to the memory, the dev ice inserts an acknowled ge bit during the 9

When data is read by the bus master, the bus

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

A stable and valid V

LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION PACKAGE OUTLINE
The NJM2391 is low dropout voltage regulators
featuring high precision voltage.
It is suitable for Notebook PCs, PC cards and hard
disks where 3.3V need to be generat ed from 5V supply.
A small TO-252 package is adopted for the space
saving.
