Leakage-current or resistance measurements must be made to determine that exposed parts are acceptablyinsulated from the supply circuit before retuming the product to the customer.Some semiconductor (solid state) devices can be damaged easily by static electricity. Such c

Alternatively, obtain and wear a commercially available discharging wrist strap device,which should be removed fo

7、r 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, toprevent electrostatic charge build-up or exposure of the assembly.3. Use only a grounded-tip

8、 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 chargessufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate electrical change su

Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to thechassis 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 precaution

11、s.8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing togetheror your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.CAUTION :AVR1700 harman/ka

In normal operation, the current source name appears on the upper line, while the surro

35、und mode is displayed on the lower line. When the on-screen display menu system (OSD) is in use, the current menu settings appear.Up/Down buttons/Tuning buttons: Use these buttons to navigate the AVRs menus. When the radio is the active source, use these buttons to tune stations according to the set

36、ting of the Tuning Mode button (see above).Surround-Mode Category button: Press this button to select a surround-sound category. Each press changes the surround-mode category: Auto Select, Virtual, Stereo, Movie, Music and Video Game. To change the specific surround-sound mode within the category, u

37、se the Surround Mode Select buttons. See Audio Processing and Surround Sound, on page 23, for more information on surround modes.Surround-Mode Select buttons: After you have selected the desired surround-mode category, press these buttons to select a specific mode within the category, such as to cha

38、nge from Dolby Pro Logic II Movie mode to Logic 7 Movie mode. Surround-mode availability depends on the nature of the source input signal, i.e., digital versus analog, and the number of channels encoded within the signal.Source Select buttons: Press these buttons to select the active source.Headphon
