(Unless this instrument is connected to the CV-5000, it cannot operate as a visual acuity
chart.)
FEATURES
This instrument has the following features:
• The active chart in which the targets are changed and moved is installed.
You can observe the patient's eye condition with the target's move.
• The animation playback function is installed. You can check a variety of visual conditions
by watching the displayed image.
• You can set the installing distance to 60cm, 80cm, 95cm, 1m and 1.5m*.

PURPOSE OF THIS MANUAL
To ensure the best use of the instrument (safely and efficiently), please carefully read "DISPLAYS AND SYMBOLS FOR SAFE USE" and "GENERAL SAFETY INFORMATION" and
familiarize yourself with the correct safety procedures prior to operating the MC-4S.
Keep the user manual on hand for future reference.
This instrument should be used in conjunction with a CV system.
There are three methods to operate the MC-4S through the CV-5000.
• Operate the MC-4S with the 1Dial Controller KB-50S.
• Connect the mouse to the monitor and operate the MC-4S with the mouse.
• Connect a personal computer to the CV-5000 and operate the MC-4S with it.
This manual is made according to operation with the KB-50S. In the case of "Mouse operation" and "Personal computer operation", you may use this manual by changing the words to
the specified ones as shown in the following table.

HOW TO ADJUST ALIGNMENT
Place the alignment emitter beside
the eye and adjust the height.
Place the alignment emitter
beside the examination window
and adjust the height.
1 Set 80cm (refer to Note 1) as the distance from the
instrument’s front surface to the patient’s eye. Then,
ask the patient to sit down on the chair.
Note 1: The installing distance can be selected from
60cm, 80cm, 95cm, 1m and 1.5m*.
* Only when selecting the H1 type.

patient and press its switch.
80cm
3 Adjust the chart indication position to the optimum within the range of 150mm at the right and left
positions and 200mm in the upper and lower positions against the front of the chart window.
• When the patient watches the chart through the TOPCON CV-5000 or other
instruments, press the alignment emitter switch beside the examination window.
NOTES
• If the alignment emitter is placed too far away in the back-and-forth direction,
sometimes the height is not adjusted correctly though it is beside the eye or
examination window.
• When using the alignment emitter, let it face the sensor detector unit of the
MC-4S.
• If the chart window is in the sunlight or if there is a window behind the patient,
the instrument may operate incorrectly or its buzzer may sound continuously
to stop its operation. Change the installation location or close the curtain or
blind.
