Warning

If any abnormal smell, sound, overheating or smoke should be detected, be sure to turn OFF

the main power immediately and then unplug the instrument from the power outlet. Continued use of the instrument may cause the instrument to malfunction or cause a re. Contact Kowa or your Kowa dealer for inspection immediately.

When replacing the ash lamp, make sure the instrument is turned OFF and then unplugged from the power outlet. Otherwise, there may occur electrical shock.

When replacing the fuse, make sure the instrument is turned OFF and un-

plugged from the power outlet.

If the fuse holder cover is removed with the instrument unplugged, there may

Warning

High-Voltage

Be sure to plug into the power outlet completely and securely.

Otherwise there may cause a re or electrical shock.

Use a designated fuse only.

Otherwise, the instrument may malfunction or a re may break out.

Make sure that the instrument is properly grounded to protect from bodily injury. Connect the plug into the three-wire grounding type outlet with ground wire.

Otherwise, there may occur electrical shock.

1. Precautions on use of medical electrical system

1) All components of this medical electrical system may be installed within a limited patient environment (a radius of 1.5

m around a patient) when all components are installed in accordance with the installation instructions using “Multi-tap with Isolation Transformer”, which is one of the system components.

2) As prerequisite for installing

or other devices) which do not comply with IEC60601-1 must be powered from Multi-tap with Isolation Transformer. The electric power to these components supplied from an electric source other than Multi-tap with Isolation

Transformer (e.g., wall outlets) may cause increased enclosure leakage current or potential difference between

protective grounds resulting in the supplying the power to the components other than the system components.

3) Any medical electrical equipment

IEC60601-1.

4) Any non-medical electrical equipment that is connected to this system to compose a medical system must comply with safety standards of IEC or ISO provisions applicable to such a non-medical electrical equipment.

5) Do not use any additional multi-tap or extension power cable other than those Kowa specied to this system.

6) Power supply the power supply through other multi-tap to the system or “Multi-tap with Isolation Transformer”.)

7) The

IEC60245/IEC60227 or higher standards.

8) Assure that the power supply is turned OFF when connecting other device to the system.

KOWA nonmyd WX is intended for use with retinal image capturing without mydriatic.

The retinal image can be stored to an image ling drive through serial interface.

1.2 System overview

This system is an instrument that enables retinal examination and retinal image capturing using infrared rays without re-

quiring the patients to take any mydriatics and uses the normal or stereo light path to capture, record and display images. Also the designated ling software installed in a PC allows you to save, register or print the captured images.

1.3 Features

1) One-touch switching Normal, SP and stereo modes.

2) Field angles available are 45° with a round mask for normal mode and 34° (20° horizontal and 27° vertical directions) with a square mask for stereo mode.

3) Functions that support mosaic mode photography.

4) A high resolution digital camera is installed.

An intuitive operation panel allows you to diagnose effortlessly.

6) Anterior segment button enables one-touch switching between anterior segment alignment and retinal alignment screens easily.
