Critical Components Information Components having special characteristics are marked s and must be replaced with parts having specifica

13、tions equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. GMeter impedance should be equivalent to 1500 ohm shunted by

14、0.15F. GLeakage current must not exceed 0.5mA. GBe sure to test for leakage with the AC plug in both polarities.

Insert the tip of flat tip (-) screwdriver to the slot on the bottom. Push up the Grille Assembly by applying force to the screwdriver. (Fig.

35、8). b. Keep pushing up the Grille Assembly gradually until it can be removed. *The Grille Assembly is fixed securely at 6 dowels. When removing it, use care not to cause a scratch or any damage to the main unit. When reinstalling it, apply quick-drying type bond to the dowels of the Grille Assembly

36、and fit it in place securely. (If it is only pushed in, it will come off easily.) 2. Removal of Amplifier Unit a. Remove 14 screws (A) and then remove the Amplifier Unit.

37、off, press the POWER key while pressing the VOLUME key and the DSP key simultaneously. This initiates the Test Program function. When the Test Program is initiated, “01 DEST-Ex” appears on the FL display. 2. Procedure for selecting and executing Test Program Using the VOLUME + (UP) key and Volume -

38、(DOWN) key, select the Test Program and then press the INPUT key to execute it. 3. Procedure for canceling Test Program There are two methods for cancellation. a. Turn off the power by pressing the POWER key of the main unit or the remote controller. b. Select the Test Program “01 DEST-Ex” and press
