When replacing a component identified with , use only the replacement parts designated, or parts with the sam

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

5、(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

6、 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 co

7、mmercially 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 ele

8、ctrostatic 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 devi

9、ces. 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 electric

10、ally 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 s

11、ure 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.

CAUTION : AVR445 harman/kardonharman/kardon RadioFans.CN 2 SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure leakage current

13、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 6

14、0Hz outlet and turn the AC power switch on. Any current measured must not exceed o.5mA. 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.

See page 39 for more information on using the tuner.When an XM Ready module is connected and activated, and when there is sufficient si

40、gnal strength for the XM system to operate, pressing this button will also change the XM Radio channel. 5 Tuner Band Selector: Pressing this button will automatically switch the AVR 445 to the Tuner mode. Pressing it again will select the AM or FM frequency band, or XM Radio. (See page 39 for more i

41、nforma- tion on the tuner.) 6 Preset Station Selector: Press this button to scroll up or down through the list of stations that have been entered into the preset memory. (See page 39 for more information on tuner programming.) 7 Input Source Selector: Press this button to change the input by scrolli

43、 4Mis pressed.When the button is pressed so that MANUAL/MONO appears in the Upper Display Line #, each press of the Tuning Selector 4Mwill increase the frequency. (See page 39 for more information on using the tuner.) This button may also be used to switch between Stereo and Mono modes for FM radio

44、reception.When weak reception is encountered, select the Manual/Mono tuning mode. Press and hold again to switch back to Stereo mode. (See pages 39 for more information on using the tuner.)

45、n the AVR is turned on.The blue illumination around the Standby/On Switch 1 will always remain at full-brightness, regardless of the setting, to remind you that the AVR is still turned on.The blue accent lighting inside the volume control will also remain at full-brightness when the panel is at 50%,

46、 but go out when the panel lights are fully dimmed. ? Tuner/FM Select Button: This button functions in two ways. Press it up, toward the top of the remote, to select the tuner as the AVRs input.The first press will call up the last-used station (or XM channel). Subsequent presses will select the las

47、t-used FM,AM and XM Radio station or channel.When the button is pressed down, toward the bottom of the remote, the last-tuned FM station is selected as the AVRs input. ?Channel Up/Down Selector: This button has no function when the AVR is being controlled, but when programmed for use with a VCR,TV,

48、cable box, satel- lite receiver or other similar product, it will change the channel up or down. See pages 4656 for more information on programming the remote. ? Delay Select Button: This button selects adjustments to the A/V Sync Delay and the individual channel displays.The first press of the butt

49、on displays an A/V SYNC DELAY message in the Lower Display Line $ and in the on-screen display, which means that you may change the amount of time that all channels are delayed together behind the video. This enables you to compensate for the loss of lip sync that may be caused by digital video processing in your display or by television stations.To change the A/V Sync
