3、CN Eachprecautioninthismanualshouldbefollowedduringservicing. 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,
4、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 damag
5、ed 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 incide
6、nce 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 w
7、rist 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 expo
8、sure 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
9、 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 conductiv
10、e 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 cha
11、ssis 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 suf

14、LED has three possible modes: Main Power Off : When the AVR is unplugged or the Main Power Switch is off, this LED is off. Standby : Amber indicates that the AVR is ready to be turned on. On : When the AVR is turned on, this LED turns white. NOTE: If the PROTECT message ever appears, turn off the AV
15、R and unplug it. Check all speaker wires for a possible short. If none is found, bring the unit to an authorized Harman Kardon service center for inspection and repair before using it again. Standby/On Switch: This electrical switch turns the receiver on, or places it in Standby mode for quick turn-
16、on. RDS: Activates RDS functions for FM Radio Channel Level Control: Press this button to adjust the output level for any amplifier channel. It may be necessary to raise or lower the level of a specific channel to compensate for the placement of the relevant speaker in the room in relation to the li
17、stening position; e.g., the center channel speaker is further away from the listening position than the front left and right speakers, so that the dialogue is too soft to hear clearly. To adjust the level of a channel, press this button once. If the desired channel is not displayed on screen and in
18、the front-panel Message Display, use the Tuning Buttons to scroll to it. When the desired channel appears, use the M N Navigation Buttons to change the level. It is recommended that you avoid changing the channel levels after you have run the EzSet/EQ setup procedure described in the Initial Setup s
19、ection, which properly adjusts all channel levels. See the Advanced Functions section for more information on manual speaker setup, including level adjustment. Remote IR Sensor: This sensor receives infrared (IR) commands from the remote control. It is important to ensure that it is not blocked. If
20、covering the sensor is unavoidable, use an optional Harman Kardon HE 1000, or other infrared receiver, connecting it to the Remote IR Input on the AVR 160s rear panel. Digital Input: To change the audio input for the current source to one of the six digital audio inputs or the analog input for the s
21、ource, press this button and use the M N Navigation Buttons to change the input. Although any digital audio input may be assigned to any source, the analog audio inputs are all permanently dedicated to the source with which they are labeled. M N Navigation: These buttons are used to navigate the AVR
22、s menus. Set: Press this button to select the currently highlighted item. Message Display: Various messages appear in this two-line display in response to commands and changes in the incoming signal. In normal operation, the current source name appears on the upper line, while the surround mode is d
23、isplayed on the lower line. When the on-screen display menu system (OSD) is in use, the current menu settings appear. Tuning: Press these buttons to tune a radio station. harman/kardonAVR 160/230 Service Manual 3 of 116 RadioFans.CN 9 ENGLISH Component Video Monitor Output Component 1 use an analog
