  The operations of DSP and DIR etc are able to checked by the information displayed on FL in this debug mode.
  This information will help to analysing digital audio no sound trouble.

  To set in Debug mode
  1. Press twice the ON/ STANDBY key while pressing the DISPLAY key.

                  e.g.                                       The version number of Microprocessor is displayed
                           M1.03/14307 A L N                 only for 3 seconds.


  2. Press + (TONE) button while the version number of microprocessor is displayed.
                   e.g.                                      The version number of DSP is displayed
                           N1.02/14210 A L A                 only for 3 seconds.

  3. Press DISPLAY button while the version number of DSP is displayed.
                  e.g.

         This means "While holding down TV/CD button, press ON/STANDBY button then release both buttons and then press
         BD/DVD button".
  e.g.-2 [DISPLAY] + [ON/STANDBY] *2  [DIMMER]
         This means "While holding down DISPLAY button, press ON/STANDBY button twice then release both buttons and then press
         DIMMER button".

INITIAL SETTING FOR SHIPPING
  Initialization of memories.
  Do the following operation.
     [CBL/SAT] + [ON/STANDBY]
  Unplug the power cord from AVR after the FL tube displays "Clear" and AVR goes standby.

CONFIRMATION OF F/W VERSION
  Do the following operation.
    1. [DISPLAY] + [ON/STANDBY]
       to display MMPU version.
        e.g. M1.03/14307ALN
    2. [TONE+]
       to display another F/W version.

    3. If FL tube displays Wi-Fi check mode then voltage-detection protectors test will be completed.

 CONFIRMATION OF UPDATE ROUTE.
    1. Do the following operation.
      1-1. set the volume level to 25(TX-NR636, DTR-30.6) or 30(TX-NR737, 838, DTR-40, 50.5).

    2. Once the above mentioned test mode is entered, voltage-detection protectors function is checked automatically first, then update
       route check will begin.
       If the result of update route check is no problem then Wi-Fi check will begin. If the result is NG then NG message will be shown on
       the FL tube.
    3. If FL tube displays Wi-Fi check mode then voltage-detection protectors test and update route check are passed.
