Service Procedures

 1.Operation check
   1) Speaker relays
       The relay shall be ON about 5 seconds after POWER is ON and shall be OFF immediately after POWER is OFF.
   2) Voltage-detection protectors
       The speaker relay is OFF immediately after D.C. 3V is put at MAIN IN INPUT terminal to check SP:B(L/R).
       The same as above when D.C. -3v is put at each place. TEST:4-02.
   3) Current-detection protectors
       a) The relay shall be ON when 3 ohm load is connected to each channel under the conditions of peak-to-zero 35V output
          for L,Rchannels and no load by using the INTEGRA ampifier series designated circuit with 200Hz square wave.Use
          TEST:2-17 MAIN IN mode input MAIN IN.
       b) The relay shall be OFF when 1.5 ohm load is connected to each channel under the conditions of peak-to-zero 35V
          output for L,R channels and no load by using the the INTEGRA ampifier series designated circuit with 200Hz square
          wave.                                                                                   White LED
       If a relay goes out, Disconnect input signal immediately.                                                 Model
       Don't continue to do this check 3 seconds or more.
   4) FL tube test (All lighting check)                                                                     A-9000R A-9070
       Please confirm the all FL display lights by TEST MODE 'TEST-1-00'.                          Normal
   5) Buttons
                                                                                                   Dimmer
       Please confirm by TEST MODE 'TEST-1-01'.
   6) DIMMER                                                                                       FL OFF
       Please push DIMMER button of Remote controller and confirm the brightness of FL display changes and the white LED
       lights(A-9000R only).
   7) Firmware version.
       Set the test mode "0-01". Please check the Firmware version.
   8) Adjustment and Confirmation of Destination
       a) Please confirm the R1293 on the BADG-0998.                                           Destination
          When destination is MJJ or MDC or MGR,It is nothing on the PWB.                      MPP        etc
          When destination is MPP, It exist on the PWB.                             R1293
       b) Set the test mode "0-02".
          Please check Model Number.
                                                                              Destination
       c) Set the test mode "0-03".
          Please check Destination.                                           MPP       etc
          Please check the display of FL refer to right table.   Display      MPP      NMPP
   9) Auto Standby (ASb) detection circuit
       a) Set the test mode "4-00".
       b) Confirm that the character of "ASb" is not displayed in FL display under the condition of no signal.
       c) Confirm that the character of "ASb" is displayed in FL display, when "-20dBV,-14dBV, 1kHz" signal is input to Line1
       Terminal.
