Q

● How to enter the test mode

While pressing [SRC] key and [ATT] key at the same time,

reset the unit.
Note: In the test mode, power supply is cut off after 30 min­utes. (This is for making the operation possible without Se­curity input even when the security is On.)

● Adjustment items

Items to be adjusted after writing on the EEPROM on which

TEL [phone] QQ 376315150 892498299

regions have been written.
As for the details of the adjustments, ref er to each adjustment
item.

• Service Information / Serial Code writing

• Chroma adjustment

• Writing Touch Adjust values

• Screen position adjustment

• Writing Security Code (Destination E only)

● How to clear the Security Code

In adjusting K destination units, if the unit starts up with Secu­rity ON, the Security Code can be cleared in the following
manner. (Other than in Test Mode)

1)In the e Security ON condition, after resetting or turning

TEL

power ON after backup OFF, then the session starts with

Security Code Input screen.

2)With the attached remote controller in the Audio SW se­lected condition, input the code with the following proce­dure.
Procedure 1: “K” input (Press Ten key [5] 2 times)
Procedure 2: “C” input (Press Ten key [2] 3 times)
Procedure 3: “A” input (Press Ten key [2] once)
Procedure 4: “Q” input (Press Ten key [7] 2 times)

3)Security Code is complete when the input screen for the
Security Code is cleared.
