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.

9) Do not turn ON the power supply until all devices are completely connected.

10) Do not place or install the devices and the system components on the unstable or inclined table.

1 System description

1.1 Intended use

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.

5)

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

7.1 Mosaic mode photography

7.1.3 Aligning and focusing

In mosaic mode photography, align for anterior segment observation only, switch to retinal observation without changing
the position of the instrument, check that the patient eye is correctly xed, and photograph.
However when you see an excessive are during retinal observation, position the digital camera appropriately before

photographing.

For mosaic mode photography, the alignment position in anterior segment observation appears in different positions as
shown in the gures below. Align appropriately so that the working dots t within the anterior segment working dot posi-

tion aids.

“FIX TARGET” that indicates the eye xation direction for you to direct a patient or the position of the internal xation tar­get visible from a patient appears on the lower right of LCD monitor during retinal observation.

Tell the patient the direction shown on the display and guide the patient’s xation.

Please note that some photographing parts may not clearly show the focus dots. In such a case, perform focusing using

macula and photograph other photographing parts without re-focusing. However you may re-focus when you can see the
focus dots clearly.

7.2 External xation target

When failed to complete xation of the patient’s eye using the internal xation target, use the external xation target (op­tional accessory: K9L-LE57) to enable the xation using the other eye.

7.2.1 Installing the external xation target

Aligning the groove on the external xation target mount and the chin rest, tighten two mounting screws to lock the lamp.

1

Adhere attached cable clamps at two places shown in the gure and x the cable with the cable clamps.

7.2.2 Using the external xation target

The external xation target illuminates by turning on the button installed on
the cable.(When it is turned ON, the internal xation target turns OFF.) “EXT”
appears on the lower right corner of LCD monitor when the external xation

target is in use.

7.3 Diopter compensation range

When clear focu s can not be obtai ne d b y foc using, pull out diop te r

compensation knob.

Pulling out diopter compensation knob to the first stop enables the minus

diopter compensation (D-) while pulling out to the second stop enables the

plus diopter compensation (D+). Slowly pull out the knob until it cricks when it

comes into one of the diopter lens insert positions. When you stop pulling the

knob before it cricks, you can not obtain a good image.

The minus or plus diopter compensation is indicated on the upper right corner

of LCD monitor.*

The focusing range of each compensation position is shown below.

No diopter lens

Plus diopter compensation + 10 m-1(D) to +35 m-1(D)

Minus diopter compensation − 32 m-1(D) to −10 m-1(D)

This instrument is a medical electrical instrument. Medical electrical instruments are requireed special attention to the

electromagnetic compatibility (EMC). The following section describes the EMC and precautions regarding this instrument.

When installing or using this instrument, read the description carefully and follow the directions described.

(The EMC of this instrument was tested based on IEC60601-1-2.)

1. Please note

that portable- or mobile-type radio frequency communication devices (RF communications instrument)

may adversely affect this instrument resulting in malfunctioning.

2. The electromagnetic compatibility (EMC) of this instrument was tested with the options and accessories shown below.

Since using an option or accessory other than those specied may cause malfunctioning of this instrument due to

interferences of other device or cause malfunctioning of other device, use only the options or accessories specied

for this instrument.

3. This instrument is not designed such that it can be used adjacent to other instrument or placing one on top of another.

Therefore, do not apply such use. Nevertheless, if such use is inevitable, it is necessary to monitor constantly if the

instrument is functioning normally after such use has been adopted.

4. Accessories and options used

with this instrument are tested for EMC when combined with instrument below. Since

using with an instrument other than that specied may cause malfunctioning of this instrument due to interferences of
other devices or cause malfunctioning of other devices, do not use any instrument other than specied below.

Option 1: CE Marking, VCCI, and FCC approved PC
