WolfVision VZ-17 - Manual (Page 19)

Symptoms: Check points:
The lightfield on the working surface is much
larger than the recorded area. Please note that the lightfield has to be a little bit larger than the recorded
area, otherwise it would not fit in all positions (on the working surface).
However if it is much too big check the following:
- First check if it is possible to adjust your monitor. Many monitors do not
display the whole picture. Some show more of the right side, some more of
the left side etc. Check if there is an UNDERSCAN function - with this
function you can display 100% of the Visualizer picture.
- If you are working with a projector (CTR) check the "blanking" of the
projector
- If you are sure that the lightfield is still much larger than the recorded area
and it is not due to a wrong adjustment of your monitor or your projector,
consult your WolfVision dealer. The size of the lightfield can be adjusted
electronically using a special WolfVision service software.
Infrared remote control does not work - Change the battery!
- If the unit cannot be controlled with the infrared remote control even from
a close distance and with a new battery it may be due to a wrong frequency
(see page 12).
VZ-47: Two horizontally compressed pictures
appear side by side on the monitor - The monitor can not display a SVGA-signal. Use a multiscan-monitor
instead

The Laser Center Marker is slightly right or
slightly left of the middle of the pick-up area. - This is not a failure of the unit. It is optically impossible that the Laser Center
Marker is 100% in the horizontal middle of the picture with every length of
the arm (macro mode on or off). But it is adjusted to be very close to the
middle with every length of the arm.
VZ-47: Too much blue in the Visualizer picture
when projected with an LCD- or DLP-Projector Adjust the white balance of the LCD- or DLP-projector.
The size of the lightfield does not change when
zooming in and out You are in the MACRO mode - press the MACRO key (#18) - see page 9
You are in the MACRO mode - press the MACRO key (#18) - see page 9
You are in the MACRO mode - press the MACRO key (#18) - see page 9
You can change the macro mode from 12x macro to 11x macro in the unit's
menu. The enlargements are not as big as before but the depth of focus is
higher in the 11x macro mode - see page 14 and on-screen help menu.
It is not possible to record the whole working
surface. The zoom stops at a largest picture of
approx. 42 x 33mm (1.6" x 1.3").
Depth of focus is not as large as usual
Depth of focus in the macro mode in too low for
my application.
Projection picture is frozen Check if the projector has frozen the picture (search for a FREEZE key on
the projector or its remote control)
VZ-47: Press the FREEZE key (#15) of the Visualizer
