1. Replacing the fuses
                 This symbol located near the fuse indicates that the
  fuse used is slow operating type, For continued protection against

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.
                 M1.04/13515AE                    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)
             -(TONE)
             e.g.
                    M1.04/13515AE                            MMPU
                                                             (Main Microprocessor)
                               +(TONE)
             -(TONE)
             e.g. D1.07/13514AEA                             DSP
                                            +(TONE)
             -(TONE)
             e.g. V1.02/13325AE                              HDMI/VIDEO Microprocessor          Version displayed
                                                                                                only for 3 seconds.

SERVICE PROCEDURE-2

5. Notes on repairs (Power supply board)
 Some parts on BAPS-1333 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.

OPERATION CHECK-1
1.OPERATION CHECK(1/3)
1-1. OPERATIONS OF VOLTAGE-DETECTION PROTECTORS.
    See "OPERATION CHECK-4,-6" for TEST MODE operation.
    NOTE: Don't connect load nor short speaker terminals.
 a. Change the state to "TEST-4-21".
 b. It tests by being automatic in order of TEST 4-21(FL+)  22(FR-)  23(C+)  24(SL-)  25(SR+)  ( 26(SBL-)
     27(SBR+) ). If TEST 4-27 is OK, it becomes the display of "TEST-4-35".
 c. It will complete, if displayed on FL TUBE as "TEST 4-35".

1-2. OPERATIONS OF CURRENT-DETECTION PROTECTORS
    See "OPERATION CHECK-4,-6" for TEST MODE operation.
 a. Change the state to "TEST-4-35".
 b. Even if you connect 3-ohm load for every channel of L, R, C, SL, SR, SBL and SBRch, a relay should not cut off.
 c. If 1-ohm load is connected for every channel of L, R, C, SL, SR,SBL and SBRch, a relay should hold the state of ON.

1-3. CONFIRMATION OF RDS (RADIO DATA SYSTEM) OPERATION (Applied to MPP/MPB/MM* type)
 a. Input 98MHz,30dB signal modurated with RDS data.
 b. When a PS information is received, the name of the station "RDS TEST" shall be displayed within 2 seconds instead
    of the frequency.

1-4. CONFIRMATION OF HEAD PHONE OPERATION.
    Confirm the Listening Mode is automatically switched to "STEREO" mode when headphones plug is inserted into
    the PHONES jack.

1-5. COMFIRMATION OF FRONT USB
    See "OPERATION CHECK-4,-5" for TEST MODE operation.
 a. Connect ipod to AVR USB port.
 b. When set to TEST 3-09, confirm that the display of AVR change device name after few seconds.

1-6. COMFIRMATION OF NETWORK
    See "OPERATION CHECK-4,-5" for TEST MODE operation.
 a. Connect the receiver to the router.
 b. When set to TEST 3-18 confirm that the display of AVR change IP adress.
 *Please wait for about 1 minute after turning on the power supply of the set when you use TEST 3-18.

1-7. CONFIRMATION OF OUTPUT SENSOR AND THERMAL SENSOR
    See "OPERATION CHECK-4,-6" for TEST MODE operation.
 a. Set the TEST MODE to "TEST 4-36".
    After light "FM STEREO" on FL display,
    the relays RL641/642 is OFF and "FM STEREO"is off .
 b. Push ON/Standby button 2 times while pushing down DISPLAY button to display CPU Debug PROGRAM version.
    Push TONE button while displaying CPU PROGRAM version to display value of temparature sensor.
    Confirm outside temperature
