 2. Safety check out
  (U.S.A. model only)
  After correcting the original service problem, perform the following safety check before releasing the unit to the customer.
  Leakage current Check
  Measure the leakage current to a known earth ground (water pipe or conduct etc.) by connecting a leakage current
  tester between the earth ground and exposed metal parts of the unit (input/output ground terminals, screw heads or metal overlays etc.).
  Plug the power supply cord directly into a 120Vac 60Hz wall socket and turn ON/STANDBY button on.
  Any current measured must not exceed 0.5mA.

 3. Memory Backup
  This model uses a EE-PROM IC in order to retain radio presets and other settings. So, memory contents will be
  kept eternally with no care.

 4. To initialize the unit
  1. Press and hold down VCR/DVR button, then press ON/STANDBY button when the unit is powered on.
  2. After " Clea r " is displayed, the preset memory and each mode stored in the memory, are initialized and
     will return to the factory settings.
                                                                                                                              TX-NR3007


SERVICE PROCEDURE-2

 5. To check version of Microprocessor, DSP and Video FW(Firmware)
 1. Press and hold down DISPLAY button, then press ON/STANDBY button when the unit is power on.
    The main microprocessor version will be displayed on Front Display for about 3 seconds.
           [e.g.]

 2. [TX-NR1007, NR3007, NR5007, PR-SC5507]
     Press (TONE) button while the version is displayed. Then, version of DSP FW will be displayed.
     In this way, as (TONE) button is pressed while a version is displayed, the next information will be displayed.
     If (TONE) button is pressed, the order will be reversed.
    [DTR-70.1, DTR-80.1, DHC-80.1]
     Press (Tone) button while the version is displayed. Then, version of DSP FW will be displayed.
     In this way, as (Tone) button is pressed while a version is displayed, the next information will be displayed.
     If (Tone) button is pressed, the order will be reversed.

    [e.g.] In case TX-NR5007
     Number depends on the version.
