3.1.1 MODEL TYPE AND REGION SETTING

Setting the Model type and Region No. for DVD Recorder
For the DVD recorder DVR-7000/KU/CA and /LB type, it is necessary to set the region No. [1 or 3] on the FLASH ROM in
the MAIN ASSY and the model type [KU or LB] on the EEPROM in the TUMJ ASSY. So when the MAIN ASSY or TUMJ
ASSY is renewed, "The Model type and Region setting mode screen" is displayed automatically.
Note : If the region No. is once set, it is unable to rewrite it. When it is necessary to change the region No., renew the MAIN
ASSY. And it is able to rewrite the once set model type on the EEPROM in the TUMJ ASSY only when the MAIN AS-
SY is renewed and setting the new region No. on the FLASH ROM.
How to set the Model type and Region No.
1. Turn the power on.
2. The setting request screen is displayed when the model type and region No. is not set.
At this time FL displays " MODE SETTING".
[ Recorder's Model and Region Setting]
Please pick out any one of the following.
Button No. Model
[ 1 : KU_MODEL<North America> Region 1 ]
[ 2 : LB_MODEL <Taiwan>
3. Enter the data according to the mode menu by the service remote control unit.
4. The recorder restarts automatically.
5. Set the shipping position. (stop + power off)
But it is omitted when making the Down Load of the system µ-com is done after this.
6. Turn off the power, then turn on the power again.
When the FL displays "MODEL MISMATCH" after connecting the AC plug to the outlet.
It displays, connecting the AC plug to the outlet when the setting is mismatched between the software setting of the model
type data on the EEPROM and the µ-com hardware pin setting of the model type in the TUMJ ASSY.
At this time, it is unable to turn on the power.
It is considered the TUMJ PCB board fault (model type hardware pin setting fault).
[Tuner control µ-com hardware pin setting of the model type]
Note :
Pin 76=Region 1, Pin 77=Region 2, Pin 98=Region 3
Pull up the correspond pin to Vcc(V+3_3M) and pull down other setting pins to GND by 10kΩ resistor.
When the screen shows the following display after turning on the power
<display 1>
< Model and Region don't match >
Model [already memorized on the TUFL-EEPROM] : KU_MODEL
Region [already memorized on the MAIN-CPU-FLASH ROM] :3
Please take the power-plug off
the plug socket
It displays, exchanging the MAIN ASSY or TUMJ ASSY,etc when the combination of model type and region No. already set
is mismatched.
After this, it is unable to operate any functions.
Match the combination between the model type and region No. setting, or renew the ASSY and set the data newly.
When the screen shows the following display after setting the Model type and Region No.
<display 2>
< You can't change and overwrite the Region No. ! >
Region was already memorized on the MAIN-CPU-FLASHROM
and you can't overwrite the different Region.
Region[already memorized on the MAIN-CPU-FLASHROM] : 3
Model-Region[that you selected just now] : KU_MODEL -1
Please take the power-plug off
the plug socket.
It displays, renewing TUMJ ASSY,etc when setting the different model type from the region No. already set in the FLASH
ROM in the MAIN ASSY.
Match the combination between the model type and region No. setting, or renew the MAIN ASSY and set the data newly.
