settings by performing thedata initialization when the current data is no longer needed,e.g. after
a relocation or system modification.
Turn the power on while holding down the MENU button. The message "MEMORY CLEAR"
appears on the monitor screen and the setting data will be initialized.
IMPORTANT
The output format is factory preset to 1080/59.94i.
4-3. Output Format Changeover
Turning the unit power on while pressing a button from 1 to 4 starts the system with the
corresponding output format, which is displayed on screen. The MV-42HS is then set to output
always in the selected format.
If the newly connected monitor does not support the current output format and cannot display
anything on the screen, you can change output formats and have it display the output format on
its screen using this feature. The factory default output format is 1080/59.94i.

should be 100 ms or more.)
5-1-4. Red / Green Tally Input (TALLY-R/G 1-4)
Displays a tally frame (red or green) when the negative logic level signal state changes.
* Red or Orange frame is selectable for simultaneous red and green tally inputs. See section
7-3-1-4. “TALLY SETUP (SYSTEM - VIDEO)”for details on simultaneous tally display
settings.
5-1-5. Internal clock correction (ADJUST IN)
Corrects the time of the internal clock as shown below when the input pulse signal level drops.
(The pulse width should be 100ms or more.)
1) When the second digit displays 1 to 29 →Correct to 0 second
2) When the second digit displays 30 to 59→Correct to 0 second and add 1 minute
5-1-6. Alarm Reset (ALARM RESET)
Resets signal loss alarms when the input pulse signal level drops. (The pulse width should be
100ms or more.)
IMPORTANT

6. Screen Display
6-1. Display Mode
The MV-42HS allows you to select 3 display modes. The display mode can beset for full screen
and multi-channel screen separately in the DISPLAY MODE menu. In multi-channel screens,
windows can be set to different modes.
See section 7-2-1-1. “FULL SCREEN SETUP 1/8 to 8/8”and 7-2-2-3. “DISPLAY MODE
(MULTI)”for details.
NOTE
If border or tally displays are turned on, black bars will be displayed. No black bar will
be displayed if both displays are turned off. Black bar settings can be changed via the
border color settings, or luminance settings; 0%(black) and 100%(white). The black
bars visualize the aspect ratio difference ofinput videos againstthe video window. See
section 7-3-1. “VIDEO SETUP 1/2 to 2/2 (SYSTEM)”for details on black bar settings.
<ASPECT 1 Mode>
Title, audio level meter, and time code displays are displayed outside the video image so that
they do not overlap. The aspect ratio of the input signal is retained.
Title, audio level meter and time code displays can be turned off or reduced in size to display a
larger video image. When turning off a title display to display a larger video image, video signal
loss detection must also be turned off, because the video signal loss alarm uses the title display
area.
