INTRODUCTION
Thank you for purchasing the TOPCON PixelChart PC-50S.
This instrument is the visual acuity chart which is used by connecting to CV-5000.
(Unless this instrument is connected to CV-5000, it cannot operate as a visual acuity chart.)
This instrument has the following features:
• The active chart in which the targets are changed and moved is installed.
You can realize the patient's eye condition by the target's move.
• The animation playback function is installed. You can check a variety of visual condition as
watching the displayed image.
• You can set the test distance by intervals of 25cm in the range of 2.5m ~ 6m.
• Maintenance-free design because the display unit is made of liquid crystal.
This instruction manual outlines the PixelChart PC-50S, including the basic operation, trouble
shooting, maintenance and cleaning of this product.
To ensure the best use of the instrument (safely and efficiently), please carefully read "DIS-
PLAY FOR SAFE USE" and "SAFETY CAUTIONS" and then use the instrument correctly
prior to operating the PC-50S.
Keep the instruction manual on hand for future reference.
This instrument should be used by connecting to the CV system.
There are three methods to operate PC-50S through CV-5000.
• Operate PC-50S with 1Dial Controller KB-50S.
• Connect mouse to monitor and operate PC-50S with mouse.
• Connect a personal computer to CV-5000 and operate PC-50S with it.
This manual is made according to the operation with KB-50S. In the case of "Mouse opera-
tion" and "Personal computer operation", understand this manual by changing the words to

PREPARATION BEFORE USE
PREPARATION BEFORE USE
INSTALLING THE INSTRUMENT
Install the instrument on the wall, using the wall-mounting metal fixture.
In addition to the wall-mounting method, you can use the Floorstand, which is an optional acces-
sory, or the stand for the commercial liquid crystal display to mount the instrument.
The interval between the screw holes in this instrument is 75mm × 75mm.
On the liquid crystal display, there is sometimes noticeably unevenness on the background due to
the disturbing light. To prevent the sunlight or disturbing light from contacting with the liquid crystal
display directly, change the installing place or direction of the instrument.
CAUTION
When installing the instrument, keep the space of 5cm or more above
and under the instrument not to block the vents on its top and bottom
surfaces. The instrument may be heated to burn someone or cause a
trouble.
CAUTION
Be careful not to damage the liquid crystal display or stain it with finger-
print, dust or others. The reliability of the measurement result may be
lowered.
CAUTION
Tighten the screws securely not to be loosened. If the screw is loos-
ened, the instrument may fall off to cause a trouble or injure someone.
NOTICE
Use the accessory screws to fix the instrument.
15
PREPARATION BEFORE USE
1 Decide the position to install the wall-mounting
metal fixture on the wall. The standard for position-
ing is that the horizontal line stamped on the wall-
mounting metal fixture should be aligned with the
center height of the liquid crystal display. Fix the
metal fixture on the wall securely with the four
wooden screws, which are the accessories.
2 Fix the four wall-mounting screws on which the clearance rings are set into the screw holes on
the instrument's rear surface securely.
3 Hang the instrument on the wall-mounting metal fixture.
CAUTION
When installing the instrument on a wall, use the wall-mounting metal
fixture, which is one of the components, and install it on the strong wall
that can support its weight. (Do not install it on the plaster-board wall.)
The instrument may fall off to cause a trouble or injure someone.
CAUTION
Fix the wall-mounting metal fixture on the wall as taking care for its
direction. The instrument may fall off to cause a trouble or injure some-
one. If the instrument is installed slantwise, the reliability of the mea-
surement result may be lowered.
