PREPARATION BEFORE USE
HOW TO ADJUST ALIGNMENT
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.
2
Place the alignment emitter beside the right eye of the
patient and press its switch.
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.
NOTES
• When the patient watches the chart through the TOPCON CV-5000 or other
instruments, press the alignment emitter switch beside the examination win-
dow.
• 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.
