(IC206) is stored.
(4 digits hexadecimal number)

0-2-3. ROM Check Sum

The revision number of ROM (IC205 (TYPE A) or IC204
(TYPE B)) that the program for the DVD system processor
(IC206) is stored.

0-2-4. Model Type

Model name is displayed. (DAV-C770 or DAV-C990)

0-2-5. Region

Model destination code is displayed. (2 digits number)

0-3-1. Sampling Check

EEPROM check at every 64 words.
It compares read data with write data of each address. When
there are discrepancies between two data, it displays error.

0-3-2. Detail Check

EEPROM check at every 1 word.
It compares read data with write data of each address. When
there are discrepancies between two data, it displays error.

Pull up/down setting check of the DVD system processor (IC206)
pin 150, 151 and 154 (for clock setting port).

SD bus data check between DVD decoder (IC701) and MPEG
DECODER (IC206).

Output the color bars for video level adjustment.

Output the test signal (1kHz sine wave) for 2 CH test.

On the Test Mode Menu screen, press the

 key on the remote

commander, and the Adjustment Menu will be displayed.

Normally, 

[10/0]

 is selected to adjust DVD (single layer), CD and

DVD (dual layer) in this order. But, individual items can be ad-
justed for the case where adjustment is suspended due to an error.
In this mode, the adjustment can be made easily through the op-
eration following the message displayed on the screen.
The disc used for adjustment must be the one specified for adjust-
ment.

Press the 

[10/0]

 key on the remote commander, and the servo set

data in EEPROM will be initialized. Then, 1. DVD-SL disc, 2. CD
disc and 3. DVD-DL disc are adjusted in this order.
Each time one disc was adjusted, it is ejected. Replace it with the
specified disc following the message. You can finish the adjust-
ment by pressing the 

[RETURN]

 button on the remote commander.

During adjustment of each disc, the measurement for disc type judg-
ment is made. As automatic adjustment does not judge the disc
type unlike conventional models, take care not to insert wrong type
discs. Also, do not give a shock during adjustment.

Press the [1] key on the remote commander and insert a DVD single
layer disc following the message. Then the adjustment will be made
through the steps, then adjusted values will be written to the
EEPROM.

Press the 

[2]

 key on the remote commander and insert a CD disc

following the message. Then the adjustment will be made through
the steps, then adjusted values will be written to the EEPROM.

Press the 

[3]

 key on the remote commander and insert a DVD dual

layer disc following the message. Then the adjustment will be made
through the steps, then adjusted values will be written to the
EEPROM.
