GP2000 Series VM Unit User Manual
Usage Precautions
Even though a video camera or computer monitor attached to the GP conforms to the
VM Unit's specified standards, the resulting image may not be acceptable. Therefore,
prior to setting up your GP system, be sure to test the operation of the GP using an
actual camera or monitor.
Video Input
• Use a standard signal (equivalent to ITU-R BT.624) as your video input signal.
Using other types of signals can cause an incorrect display. Also, even if the input
signal used conforms to the specified standard, the display can be incorrect, de-
pending on signal quality. (This may occur when the signal contains a special
signal, such as a copy-guard signal.)
• When inputting video signals such as search-and-playback or still-frame playback
from your VCR, you may encounter problems such as the image not being updated.
• The image quality can vary depending on the display size selected.
• When using PAL format (768 x 576 dots) with the GP-2500 (640 x 480 dots), the
standard (no-magnification) display cannot show all of the images in one screen.
As a result, The images at the far right and bottom of the GP may be hidden. In
this case, scroll the screen to view these images.
• When connecting the certain video input signal to the maltiple units by using "T
junction connection" or "Daisy chain connection", the image cannot be displayed
on the GP correctly.
RGB Input
• When using RGB signal input, a blue-background screen may appear momentarily
while the screen is adjusted or when a PC screen is switched. This phenomenon is
normal and the VM Unit is not malfunctioning.
• With some types of RGB signals, the displayed images or RGB output images may
contain noise or may be blurred during the screen adjustment. It is possible that
these problems may not be able to be fixed, given the VM Unit's available range of
adjustment.
• Image quality may vary depending on the display size selected.
RGB Output
• Without the correct set up, a factory-set GP unit may not provide the desired dis-
play images.
• Depending on the device connected to the VM Unit, it is possible that images may
not be properly displayed or may not be fully corrected. Limitations in the range of
the GP unit's TFT LCD screen adjustments may cause images to extend offscreen.
• Do not use paint thinner or organic solvents to clean the VM Unit. To remove dirt,
use a tightly squeezed, soft cloth moistened with a dilute solution of a neutral
detergent.
