9-IMAGE MEMORY
You can store 9 images and recall them by just pressing one of the numerical keys
(#22) on the infrared remote control:
Storing an image: Press one of the memory keys (#22) for more than 2 seconds
Recalling an image: Press one of the memory keys (#22) quickly
By pressing the "All" key (#25) a split screen with all 9 pictures of the memory can
be displayed.(see image on the left).
When pressing the ALL key (#25) for 4 seconds, a menu appeares on the screen
asking if you would like to erase all stored pictures (black picture) or if you would
like to fill the memory with "snapshots". When choosing "snapshot" the Visualizer
stores a new image every second until the 9 memory locations are full.
TEXT ENHANCEMENT
For improving the readability of texts, sketches and x-rays press the TEXT-key (#16). This mode enhances the
contrast of the picture. Please note that in this mode the colors are darker than usual. To switch off the text
enhancement mode press the TEXT-key again.
Picking up a complete vertical (portrait) letter or A4 page has
always been a critical issue for a Visualizer, because the
image is always picked up in a horizontal (landscape) format.
So the camera could only use 50% of its pixels to pick up a
vertical (portrait) page. WolfVision's
º
"Image turn" mode solves
this problem.
Just place your letter (or other vertical object) on the working
surface horizontally and zoom in on it completely (Now about
90% of the pixels of the built-in camera are used to pick up the
letter.)
Then press the IMAGE TURN key (#15). The Visualizer turns
the picture electronically 90 and outputs it the right way up
with much higher resolution than in normal mode. The left
and right margins are black.

IMAGE TURN MODE (for higher resolution)
If a computer is connected to the External RGBHV input (#32) of the Visualizer, the Ext/Int switch (#24) can be
used to switch between the Visualizer and computer image that is displayed to the audience.
The signal from the computer is just looped through the Visualizer and is not processed in any way. In order to
avoid that your projector or monitor adjusts itself when switching, it is recommended that you set the output of the
computer to the same signal format (SXGA, XGA or SVGA) and vertical frequency (75 or 60Hz) as the Visualizer.
Please note that the picture from the External RGBHV input (#34) can not be output on the PAL/NTSC video
outputs (#36, 37) and the digital section of the DVI (#29) output!
EXTERNAL INPUT
SYNC OUTPUTS
(for specialists only)
In most installations it is not necessary to change the sync settings of the Visualizer, because most monitors or
projectors automatically detect the required sync mode.
The default sync setting of the Visualizer's RGBHV outputs (#32, 33 and 35) is separate horizontal (HD) and
vertical (VD) sync-signals. However, if your display-device does not support separate sync-inputs, you should
switch the Visualizer to C-SYNC (i.e. the combined vertical- and horizontal-sync-impulses are output on the S/HD-
connector). You can switch between C-SYNC and VD/HD-SYNC in the on-screen menu (see page 15). If you want
to use sync-on-green you can change between sync-on-green on and off in the on-screen menu. When sync-on-
green is switched on, you should only connect R, G and B. Monitors which do not support this mode often display a
green picture. Please note that the sync-outputs are the same on all RGBHV outputs. So if you use multiple
display-devices you should use a mode which is supported by all display-devices.
