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.
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.
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.

Main Power Switch: This mechanical switch turns the power supply on
or off. It is usually left on, and cannot be turned on or off using the remote
control.
6-/8-Channel Inputs: Connect the multichannel analog audio outputs
of a non-HDMI player (DVD-Audio, SACD™, Blu-ray Disc™ or HD-DVD, or any
other external decoder) to these jacks.
Coaxial 1/2 and Optical 1/2/3 Digital Audio Inputs: If a source
has a compatible digital audio output, and if you are not using an HDMI
connection for audio for the device, connect it to one of these jacks to hear
digital audio formats, such as Dolby Digital, DTS and linear PCM. Use only one
type of digital audio connection for each source.
Coaxial Digital Audio Output: If a source is also an audio recorder,
connect the Coaxial Digital Audio Output to the recorder’s matching input for
improved recording quality. Only PCM digital audio signals are available for
recording. Both coaxial and optical digital audio signals are available at this
Digital Audio Output.
Zone 2 Infrared (IR) Input: Connect a remote IR receiver located in the
remote zone of a multizone system to this jack to control the AVR (and any
source devices connected to the Remote IR Output) from the remote zone.
Remote Infrared (IR) Input and Output: When the remote IR
receiver on the front panel is blocked, connect an optional IR receiver to the
Remote IR Input jack. The Remote IR Output may be connected to the Remote
IR Input of a compatible product to enable remote control through the AVR.
Remote IR Carrier Output(AVR 460 only): This output is similar in
function to the Remote IR Output, with the difference that this jack outputs
the full infrared signal as received by the AVR’s IR sensor or the Remote IR
Input, while the Remote IR Output jack outputs a “stripped” signal that has no
carrier frequency.
