If there is no picture on the video monitor, go to the Troubleshooting section. One possible cause is that the
YUV output is enabled, which will blank out all other video outputs. This is also covered in the Advanced
Features section.

ABOUT THE SCAN CONVERTER
There are 3 ways to control the Scan Converter:
By the Buttons on the Front Panel in conjunction with the LCD (Liquid Crystal Display).
By the Infrared Remote Control unit.
Directly from the computer via the RS-232 Serial Port.
Each control method has its own section of this manual to describe the operation.
Shown below is a diagram that indicates the main features of the front panel of the VP-706SC. All three Scan
Converter models appear the same and their basic operation is identical.

LCD
- The top line of the liquid crystal display (LCD) always indicates the current mode of the Scan
Converter. At power-up, this will be the 'Status' mode, but will change, depending on what the user
wants the unit to do. The bottom line always indicates the value that is or will be adjusted by the various
control methods
Power On LED
– When the Scan Converter is powered up, the button labeled POWER will illuminate
green.
Menu Button
– This is used to initiate Front Panel control of the unit and select the various options and
features to change.
OS/US (-) Button
– This is a dual-purpose button that will be described in a moment, but is normally
used to decrease (or de-select) the currently displayed option or feature.
Freeze (+) Button
– This is another dual-purpose button, but normally used to increase (or set) the
currently displayed option or feature.
Audible Indicator
– The internal sounder is used to confirm that a setting has changed, and to indicate
that the Scan Converter is saving the settings to non-volatile memory. You will hear it regularly during
normal use, but it can be disabled if needed.
6.1 Quick-Set
Buttons
These are the dual-purpose buttons described earlier and only function when in Status mode (i.e. the top line of
the LCD says 'Status'). They are provided for quick access to certain often-used functions - i.e. Toggling
Underscan /Overscan and Freeze On/Off.
6.2 Special Button Usage on Power-up
Certain buttons can be held down when applying power to the unit, to perform certain functions:
Factory Reset –
Hold down both the OS/US and Freeze Buttons when turning the unit on. This will
reset the unit to Factory Settings (and set the unit into NTSC video mode). It should only be used if the
unit's settings give an invalid output that the user cannot exit from, as all user-settings will be lost.
Note
-
use this procedure as a last resort.
Set to NTSC Mode
– This is done by holding the OS/US Button down when turning on the unit. This
changes the non-volatile PAL/NTSC setting to NTSC, and will be remembered even when power is
removed.
Set to PAL Mode
– This is done by holding the Freeze Button down when turning on the unit. This
changes the non-volatile PAL/NTSC setting to PAL, and will be remembered even when power is
removed.
