SERVICE PROCESURE


 1. Replacing the fuses

                    This symbol located near the fuse indicates that the
    fuse used is show operating type, For continued protection against
    fire hazard, replace with same type fuse, For fuse rating, refer to
    the marking adjacent to the symbol.

                  Ce symbole indique que le fusible utilise est e lent.
    Pour une protection permanente, n'utiliser que des fusibles de meme
    type. Ce demier est indique la qu le present symbol est apposre.

 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. To initialize position
   Power Switch                     ON (Pull out the power cord at power on stage)
   4 ohm / 6 ohm                    6 ohm
   Auto Power Down                  MMA: ON, Others: OFF
   Input selector                   Unbalance
                                                                                                                                                                                                                                                                                                                                                                                                                                       DTA-70.1

ADJUSTMENT PROCESURE

 1. Adjustment of Idling current

   Set the voltage point at P6070 to P6078 to 3.0mV by adjusting R6040 to P6048,
   under the conditions of no input signal and no load, immediately after power ON.

                                   L / C/ R / SL / SR / SBL / SBR / LH / RH
                                  Below   3mV                                                                                             3mV
                                  Between 3 to 4mV                                                                                        Leave it as it is.
                                  Over    4mV                                                                                             4mV

        Re-adjust by following procesure after 4 to 6 munis of heat running.

    NOTE:
    Set R6040 to R6048 to minimum position before power ON.
    Equip series 1/4W 100-ohm resistor near the terminal respectively in the each poles.
