Components identified with the IEC symbolin the parts list are special significance to
4、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 pa
5、rts 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 int
6、egrated 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,
7、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 electrica
8、l 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. S
9、ome 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 packag
10、e 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 d
11、evice, 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 har
12、mless 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. CAUTION : AVR310 AVR310 harman/kardon 2 RadioFans.CN 1. Inspect all lead dress to make certain that leads are not pi

Note that the Power Indicator surrounding the switch 3 will turn green when t
19、he unit is on. 3 Power Indicator: This LED will be illumi- nated in amber when the unit is in the Standby mode to signal that the unit is ready to be turned on.When the unit is in operation, the indicator will turn green. 4 Headphone Jack:This jack may be used to listen to the AVR 310s output throug
20、h a pair of headphones. Be certain that the headphones have a standard 1/4 stereo phone plug. Note that the main room speakers will automatically be turned off when the headphone jack is in use. 5 Selector Buttons:When you are establish- ing the AVR 310s configuration settings,use these buttons to s
21、elect from the choices available, as shown in the Main Information Display . 6 Tone Mode: Pressing this button enables or disables the Bass and Treble tone controls. When the button is pressed so that the words TONE IN appear in the Main Information Display , the settings of the Bass the tuner will
22、automatically scan for the next station with an acceptable signal and then stop. 9 Tuner Band Selector: Pressing this button will automatically switch the AVR 310 to the Tuner mode. Pressing it again will switch between the AM and FM frequency bands. (See page 29 for more information on the tuner.)
23、) Preset Stations Selector: Press this button to scroll up or down through the list or stations that have been entered into the preset memory. (See page 29 for more information on tuner programming.) ! Input Source Selector: Press this button to change the input by scrolling up or down through the l
24、ist of input sources. FM Mode Selector: Press this button to select Auto or Manual tuning.When the button is pressed so that the AUTO Indicator X lights, the tuner will search for the next station with an acceptable signal when the Tuning Selector 8uis pressed.When the button is pressed so that the
25、AUTO Indicator X is not lit, each press of the Tuning Selector 8u will increase the frequency. (See page 29 for more information on using the tuner.) # Digital Optical 3 Input: Connect the opti- cal digital output of an audio or video product to this jack.When the Input is not in use, be certain to
26、keep the plastic cap installed to avoid dust contamination that might degrade future performance. $ Digital Coax 3 Status Indicator: This LED indicator will normally light green to show that the Digital Coax 3 jack is operating as an input. When the jack has been configured as an output the indicato
27、r will turn red to show that the jack may be used for recording. (See page 19 for more information on configuring the Digital Coax 3 jack.) % Digital Coax 3 Jack: This jack is normally used for connection to the output of portable audio devices, video game consoles or other products that have a coax
28、 digital jack. It may also be configured as an output jack, to feed a digital signal to a CD-R, MiniDisc or other digi- tal recording device.

32、Theater mode is in use. O Night Mode Indicator: This indicator lights when the AVR 310 is in the Night mode, which preserves the dynamic range of digital program material at low volume levels. P Multiroom Indicator: This indicator lights when the multiroom system is active. Note that it will remain
33、lit when the multiroom system is in use even though the main room system is in the Standby mode and all other indicators are dark. (See page 34 for more information on the Multiroom system.) Q Speaker/Channel Input Indicators: These indicators are multipurpose, indicating either the speaker type sel
34、ected 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
35、“Large” speakers are selected.When none of the boxes are lit for the center, surround or subwoofer channels, no speaker has been selected for one of those positions. (See page 21 for more infor- mation on configuring speakers.) The letters inside each of the center boxes display active input channel
36、s. 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. (See page 28 for more informa
37、tion on the Channel Indicators.) R Preset Number/Sleep Timer: When the tuner is in use, these numbers indicate the spe- cific preset memory location in use. (See page 29 for more information on preset stations.) When the Sleep function is in use, these num- bers show how many minutes remain before t
38、he unit goes into the Standby mode.
