There are five main commands in the Mirr time Adjust menu as
shown in the figure above. The functions of each command are
described in the following page.
1. CD Mirr time Check
This command checks the Mirror time value for CD disc.
2. DVD Mirr time Check
This command checks the Mirror time value for DVD disc.
3. Threshold
This command displays the threshold value between CD and DVD
mirror time.
4. Save to EEPROM
This command saves an adjusted mirror time value to the EEPROM.
5. Default set MIRR time
This command will set CD and DVD mirror time to firmware default
value.
[Open] / [Close]
Pressing the Open / Close button controls the tray for disc change
during mirror time adjustment.

Press [0] button to return to previous menu.
6-1. GENERAL  DESCRIPTION
The Mirror Time and IOP measurement allows you to make
diagnosis and adjustment simply by using the remote commander
and monitor TV. The instructions, diagnosis results, etc. are given
on the on screen display (OSD).
The Mirror Time and IOP measurement is required in such events
where servicing a DVD-Player includes changing the Base Unit
(BU). For each new BU to be used with a certain MB-113 board,
Mirror Time and IOP measurement need to be carried out.
