Cancellation of running3 to 8 : Press the [POWER] key The number of count and an error cord are displayed in running. Playback contents in a running mode CD The first track is played for 30 seconds. The last track is played for 30 seconds. (The last truck is played in the case of less than till the last for 30 seconds.) DVD 2layer disc Title 1 (the L0 layer internal circumference) is played for 30 seconds. Title 12 (L0 layer circumference) is played for 30 seconds. Title 24 (L1 layer internal circumference) is played for 30 seconds. 1layer disc First chapter of title 1 is played for 30 seconds. The last chapter of title 1 is played for 30 seconds. For main ROM correction and panel ROM correction, prepare two pieces of disc. (Do not put both data in one piece of disk.) Insert the disc which ROM correction data were written in at. Folder name : ROM Correction File name : Please Wait Folder name : ROM Correction File name : OK 1940 (Indication is different by ROM correction IC.) If OK is displayed, ROM correction is completion. Disc is ejected automatically. Pull the power supply cord and wait more than 30 seconds. (Even reset is possible.) Switch on the main body again and confirm a version. Confirmation method of a version Keep this state more than 2 seconds while continuing pressing the [DISP] button, [VOLUME+] button and [EJECT] button sequentially to enter this set in service mode 3. Select the service mode and press the [OK] button. Select the version and press the [OK] button. ROM correction is completion if displayed on a screen as follows. PANEL : panel ROM correction MAIN : main ROM correction ROM correction version PANEL V [V001] When it was confirmed a version without reset, a part of [V001] is displayed in [E001]. When a ROM collection is not completed even if writing of EEPROM is completed, this indication appears. Movement of this case is movement before the ROM collection.
