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

D Speaker/Channel Input Indicators: These indicators are
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
ENGLISH
will light to display the channels being received at the digital input.
When the letters flash, the digital input has been interrupted.
(See page 31 for more information on the Channel Indicators).
NOTE: When you have reassigned the surround back speakers to the
remote zone using the MULTI ROOM SETUP menu, the boxes that indicate
the presence of the surround back speakers will automatically disappear,
reflecting the fact that the main listening area is now configured for
5.1-channel operation. (See page 33 for more information on reassigning
the surround back speakers for multiroom use.)
E Surround Modes: Press this button to select a surround sound
(e.g.,multichannel) mode. The Surround Modes menu will appear on
screen, and the menu line will appear on the lower line of the front-
panel display.
Use the front-panel or remote KL Buttons to highlight a different
menu line: Auto Select, Virtual Surround, Stereo, Movie, Music or Video
Game. Each line represents a type of audio signal, and is set to the
surround mode the AVR will automatically select when it detects the
audio signal.
You may manually select a different mode for each type of audio. Press
the OK Button when the menu line is highlighted, and the available
surround mode options for the current signal will appear. Use the KL
Buttons to select the desired mode, and press the OK Button to engage
it. Press the Back/Exit Button to exit the Surround Modes menu and
display the next higher menu in the hierarchy.
See the Advanced Functions section for more information on surround
modes.
F Back/Exit: Press this button to return to the previous menu. When the
main AVR menu is displayed, press this button to exit the menu system.
G Digital Optical Front Input: Connect the optical digital audio
output of an audio or video product to this jack.
H Digital Coax Front Input: This jack is normally used for connection
to the output of portable digital audio devices, video game consoles or
other products that have a coax digital jack.
I Video Front Input Jacks: These audio/video jacks may be used for
temporary connection to video games or portable audio/video products
such as camcorders and portable audio players.
J Source List: Press this button to select a source device, which is a
component where a playback signal originates, e.g., DVD.
