INTRODUCTION

Thank you for purchasing the TOPCON Mirror Chart MC-4S.

INTENDED USE / INDICATIONS FOR USE

This instrument is the visual acuity chart which is used in conjunction with the CV-5000. (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*. * Only when selecting the H1 type.

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.

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.

SYSTEM CLASSIFICATION

Type of protection against electric shocks: This instrument is classified as Class I equipment. (MC-4S Mirror Chart)/Internal power supply device (Alignment emitter)

Class I equipment does not depend only on basic insulation for protection against electric shocks, but also provides a means of connection to a protective earth system of facilities so that metal parts that come into contact do not become conductive while the basic insulation is in failure. "Internal power supply device" is a device that can be operated by the internal power supply.

Degree of protection against harmful ingress of water: IPx0 (MC-4S Mirror Chart and alignment emitter)

The MC-4S has no protection against ingress of water. (The degree of protection against harmful ingress of water defined in IEC 60529 is IPx0.)

Classification according to the method(s) of sterilization or disinfection recommended by the manufacturer: not applicable. (MC-4S Mirror Chart and alignment emitter)

The MC-4S has no part to be sterilized or be disinfected.

Classification according to the degree of safety of application in the presence of a flammable anesthetic mixture with air or with oxygen or nitrous oxide: Equipment not suitable for use in the presence of a flammable anesthetic mixture with air or with oxygen or nitrous oxide. (MC-4S Mirror Chart and alignment emitter)

The MC-4S should be used in environments where no flammable anesthetics and/or flammable gases are present.

Classification according to the mode of operation: Continuous operation. (MC-4S Mirror Chart and alignment emitter)

Continuous operation is the operation under normal load for an unlimited period, without the specified limits of temperature being exceeded.

When the patient or inspector may touch the devices (including the connecting devices) or when the patient or inspector may touch the person in contact with the devices (including the connecting devices), the patient's environment is shown below. In the patient's environment, use a device conforming to IEC60601-1. If you are compelled to use any device not conforming to IEC60601-1, use an insulation transformer or the common protective earth system.

REQUIREMENTS FOR THE EXTERNAL DEVICE

The external device connected to the analog and digital interfaces must comply with the respective IEC or ISO standards (e.g. IEC 60950 for data processing equipment and IEC 60601-1 for medical equipment). Anybody connecting additional equipment to medical electrical equipment configures a medical system and is therefore responsible that the system complies with the requirements for medical electrical systems. Attention is drawn to the fact that local laws take priority over the above mentioned requirements. If in doubt, contact your dealer or TOPCON(see the back cover).

At 80 MHz and 800 MHz, the higher frequency range applies. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

abField strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones

To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the MC-4S is used exceeds the applicable RF compliance level above, the MC-4S should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the MC-4S.
