In setting up BAL/FAD, the setting “MIN CENT MAX” can be made by 1 click. In setting up Xover, the setting “MIN MAX” can be made by 1 click. In setting up Tone, the

30、setting “MIN CENT MAX” can be made by 1 click. The default setting of Tone (EQ) shall be Flat. The default setting of System Q shall be Off. When there is Digital Out terminal, the setting shall be such that the output is always On. The default setting of Line Mute shall be On. 4.9 AVIF The default

31、setting of AVIN Interruption shall be On. The default setting of R-CAM Interruption shall be On. Normally an interruption occurs when the R-CAM is de- tected. Reverse condition shall be always On. The default setting of SP for NAVI interruption shall be Front ALL. Use Tenkey 3 on the remote controll

33、Mode shall be SYNC. 4.11 DC Offset DC Offset detection status (normal/error) clear Clear DC Offset detection information of E2PROM with DC Offset detection information Clear key on the Ser- vice Information screen. DC Offset detection information is displayed on the Infor- mation screen/Service Info

34、rmation screen. In the Test mode, even if DC Offset is detected, it is not written into E2PROM. However, the detection operation shall be carried out and when the DC Offset is detected, the Protect shall be dis- played and it becomes all CH Mute operation. Volume setting can be changed to the follow

35、ing settings by pressing Tenkey 2 on the remote controller. Source : DVD Assigned DISC : KTD-02A Assigned Track : 15 (20Hz, 0dB) Assigned VOL : 26 Step (Low) 4.12 Flicker adjustment q Use Tenkey 0 on the remote controller to turn the Flicker adjustment On. w Slide the monitor at the fore ground, and

36、 make the screen mode FULL, and set the video to “KVT: VIDEO, DDX/ DNX: R-CAM”. e Press Tenkey 0 on the remote controller during the fl icker adjustment to turn the adjustment Off. r Slide the monitor innermost (Test mode default value), make the screen mode FULL, and make the video as it is changed

37、 and used during the adjustment. The OSD can be shown normally during the fl icker ad- justment. When changing R-CAM of DDX/DNX, the detection at the Reverse terminal is neglected and the system is switched to R-CAM. 4.13 Driver for Panel Mechanism Motor (Only in KVT Series) With the condition when

38、AUTO key is pressed and hold, the driver port for motor shall be turned On. While AUTO key is being pressed, the motor is turned On in reverse direction when the key is On for the fi rst time and the motor is stopped when the key is Off. With the key is pressed On for the second time, the motor is t

39、uned On in the normal (forward) direction, and the mo- tor is stopped when the key is Off. Repeat the same steps in the succeeding procedure. 4.14 Clearing E2PROM contents Clear the E2PROM contents which should not remain in it when shipping the unit. KVT: EJECT key + AUTO key DDX/DNX: SRC key + FNC

40、 key Clear the contents of E2PROM using the above key + Reset key. Clear OK : Key illumination blinks (twice) Clear NG : Nothing happens. The following information is cleared: DC Offset information / Memory information / Retailer mode information / Service information If a jig is connected and the r

41、egion is written in, the follow- ing information shall be cleared. When region code has been written in E2PROM, contents TEST MODE 23 DDX5022/5022Y/5032/5032M/512/52RY DNX5120/512EX/5220/5220BT of the E2PROM are not cleared if the same region code is written. Only when the different region code is w

42、ritten, contents of the E2PROM are not cleared. Serial No. / Security code / Touch correction / HPOSI correction / Chroma adjustment DC Offset information / Memory function / Retailer mode information / Service information Note: Since the above data is cleared (un-defi ned) when the E2PROM has been

43、replaced during the service, it is required to re-adjust the data in the Test mode. 4.15 Security Code writing-in When entering the Security Code that is defi ned as a pair of the serial number of the product (for other destinations than K/R), use Security Set Up key on the Setup screen to call the

44、Security screen. Only when the Security Code of E2PROM of the product for other destinations than K/R is blank, Set key is shown and press that key. In the Security Code Writing screen, run the same opera- tion as when registering Security Code in normal mode, and press the Enter key to start writin

45、g. Note: The Security Code to be entered in the above step is the set-specifi c code linked to the serial No. Writing of the code is successfully completed when “Complete” is displayed, and if “NG” is displayed, the writing the code is unsuccessfully completed. Note: If “NG” is displayed, transfer t

46、o the Test mode again and repeat the above process from the 1st step. When the Security Code is Blank, the system is turned OFF in 30 minutes. Note: In order to turn Security Off in the product whose destination is K/R while the Security of that product is turned On, turn the Security off from the S

47、etup screen, or use the following steps to turn the Security off on the Security Code Input screen shown when the system is turned on: Press Tenkey 5 on the remote controller twice Tenkey 2 four times Tenkey 7 three times. 4.16 Other Do not operate the Back Up Memory function during the Test mode.
