Hold Buttons
Certain buttons can be held together when the unit is on to perform other functions.
Store Current Settings
- This is done by holding the MENU and FREEZE (+) Buttons in together for
about 2 seconds and can be done at any time. This stores the current settings (e.g. Overscan, YUV
Mode, etc.) in Non-Volatile Memory and cause the Scan Converter to come up in those modes the next
time it is turned on.
This option will emit a high-pitched beep when complete to indicate that data has been successfully stored. If
you manage to store an invalid setting, you may need to do a Factory Reset (see above).
If you hear high pitch beeps at other times, it indicates that other data is being stored into memory – e.g.,
information the Scan Converter has deduced about the graphics resolution coming from your computer, such as
when you change your screen resolution.

MENU STRUCTURE AND FEATURE CONTROL
This section goes through the Main Menus available via the LCD and what control they provide over the Scan
Converter. Internally, the Infrared and Serial control links change the features in the same way as the buttons,
so this section is required reading whatever the final method of control is likely to be.
Advanced features are covered in a later section of this manual.
7.1 Status
Mode
In Status Mode, you are presented with a summary of some of the current settings. Almost all of these are
repeated (and adjustable) elsewhere in the menu system, but some are not.
7.1.1
Overscan - Quick Set
This is called Quick Set because you don't have to scroll through menus to alter this option. The OS/US (-)
Button toggles between Underscan and Overscan.
Underscan Mode
(sometimes know as Compress mode) will leave a border around the image.
Overscan Mode has no border and the displayed image, when set correctly, is larger than the video
monitor screen.
If Underscan and Overscan don't give you the image sizes you expect (for example, Overscan still shows
a border), then make sure you perform the AutoTrack™ function, which is described later in this section
of the manual.
Both the Underscan and Overscan sizes are user-adjustable and the method of doing so will be described
later under the 'Screen Size...' section.
7.1.2
Freeze - Quick Set
This is another Quick Set button, labelled 'FREEZE'. When pressed the first time, the unit will enter a special
mode where the video image and all other features are frozen.
Freeze will remain active until disabled by pressing 'FREEZE' again, and the whole unit will remain
frozen until this happens.
No other features are accessible while in Freeze Mode, except the RESET button on the Remote Control
unit.
7.1.3
Total Lines - Information
This is for information only and will appear when in Status Mode to show how many scan lines are in the
incoming computer picture. It includes blanked lines that are not normally viewable, so a 1024x768 image
might actually have a total of 806 lines in it, with 38 of them used for vertical blanking.
7.1.4
Vert Freq - Information
Again, this is just for information and shows the Vertical Refresh rate of the incoming computer signal.
Multiply this by the 'Total Lines' value to give the Horizontal Scan Rate. While high refresh rates are generally
more acceptable when displayed on computer monitors, Scan Converters prefers a low refresh rate so that their
capture circuitry has more time to capture more pixels, thus giving a clearer picture.
