3.1. While a highlighted indicator is displayed on the right side of the
Market denotation, push ENT button on the remote controller.
With each push the indicator will advance as shown below.
WM -> SFC -> EUR -> S18 -> SS -> PA
3.2. Specify the code of the model in accordance with the Market/
Region Setup Table above.
(In DWM-380 model, the code is the same as the initial one
"WM". Advance to the next procedure without making any
changes.)
3.3 Once the desired code is displayed, push p button to move the
highlighted indicator to the Region input area.

4. Setting REGION code
4.1 While a highlighted indicator is displayed on the right side of
the Region denotation, push ENT button on the remote
controller. With each push the indicator will advance as
shown below.
1 -> 2 -> 3 -> 4 -> 5 -> 6
4.2 Specify the number of the model in accordance with the
Market/Region Setup Table above.
(In DWM-380/US models, the number is the same as the
initial one "1". Advance to the next procedure without making
any changes.)
4.3 Once the desired number is displayed, push p button to move
the highlighted indicator to Exit area.
5. Saving settings
5.1 Make sure that the Market and Region settings are properly
set.
(If any of the settings are incorrect, you can make a change
by moving the indicator using p button, and following
procedures 3 and 4 above. )
5.2 After ensuring that the settings are all correct, push ENT
button while the indicator is on Exit area. The settings are
now saved.
6. Finishing settings
6.1 After a few seconds, the Internal Setup screen disappears,
and then the Service Mode screen is displayed again for
three seconds as shown on the right.
You should check the settings.

D. IMPORTANT NOTE
1. Once the "Market/Region" settings are written into EEPROM (IC801) on the DVD substrate, they cannot be reset.
(However, updating the system using CD-R enables you to make new settings.)
2. While the Internal Setup screen is displayed, pushing the Power button enables you to terminate the operations without
making any settings.
HOW TO LOAD SOFTWARE FOR MPEG P.W.BOARD
1. Power on, then open tray.
2. It take on CD-ROM for UPDATE software to the tray, and tray close.
3. Display " UP DATE" in the TV screen.
4. For the time being, tray open and FL display remain "UP DATE".
5. When software loading finished, FL display "STANDBY".
6. Next, set up market code and region code by "SERVICE MODE"
CD-ROM part code is "0PRADC9635--A".

IEC SYMBOL
BE OF SPECIAL SIGNIFICANCE. WHEN REPLACING A COMPONENT IDENTIFIED BY
PARTS DESIGNATED, OR PARTS WITH THE SAME RATINGS OF RESISTANCE, WATTAGE OR VOLTAGE THAT ARE DESIGNATED
IN THE PARTS LIST IN THIS MANUAL. LEAKAGE-CURRENT OR RESISTANCE MEASUREMENTS MUST BE MADE TO
DETERMINE THAT EXPOSED PARTS ARE ACCEPTABLY INSULATED FROM THE SUPPLY CIRCUIT BEFORE RETURNING THE
PRODUCT TO THE CUSTOMER.
CAUTION : Regular type resistors and capacitors are not listed. To know those values, refer to the schematic diagram.
IN THE PARTS LIST AND THE SCHEMATIC DIAGRAM DESIGNATED COMPONENTS IN WHICH SAFETY CAN
