. Micom Reset

During STANDBY mode , push the ‘STOP’ button 5 Second. If VFD blinking, reset is finished.

. Micom Update (Only for Flash Micom)

METHOD 1) MAIN PCB UTCON1 for update JIG.

To update Micom, it need Computer, Rom Writer, USB Cables

METHOD 2) Insert USB Memory, and play. ‘Updating’ will be displayed. Set will be power off when finish.

. Micom & MPEG Version Check

1) POWER ON

2) CD open status

3) Push the number NEXT for 5 seconds, check the micom version

4) Push the number PREVIOUS for 5 seconds, check the mpeg version

. MPEG Update

1) Prepare rom file at USB Memory

2) Insert USB Memory, and play. ‘Updating’ will be displayed. Set will be power off on

3) The disc is automatically ejected. (If you use USB memory, detach USB memory)

. MPEG Reset 1) During “No Disc” Displayed, push the stop button 5 seconds. After displayed ‘INITIALIZE’ set will power off automatically.
