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 the unit
  Press ON/STANDBY button while pressing down CBL/SAT button
  when the unit is POWER ON, then the FL displays "CLEAR", and turn to STAND-BY. Remove power cord from power line.

4. To check version of each Firmware
  a. Push ON/STANDBY key while pushing down DISPLAY key to display MMPU(Main Microprocessor) version.
            e.g.
                  1.01/13515AE8                   Version of MMPU displayed only for 3 seconds.

  b. In display version, +(TONE) key and -(TONE) key are pushed to display another F/W version.

                                             +(TONE)

SERVICE PROCEDURE-2

5. Notes on repairs (Power supply board)
 Some parts on BAPS-1353 may remain high voltages even after the power cord is disconnected from AC power source.
 Before starting repair and any other work , please discharge C9002 by connecting resistors between its terminals.
 See the figure below(recommended resistor spec: 5 k ohms/ 10W)
 It is dangerous to touch the "HIGH VOLTAGE PRIMARY" area surrounded by white lines without discharging.
