SAFETY INFORMATION
Accessory equipment connected to the analog and digital interfaces must be certificated
according to the respective IEC/EN standards (e.g. IEC/EN 60950 for data processing
equipment and IEC/EN 60601-1 for medical equipment).
Furthermore all configurations shall comply with the system standard EN 60601-1-2:2007.
Everybody who connects additional equipment to the signal input part or signal output part
configures a medical system, and is therefore responsible that the system complies with the
requirements of the system standard EN 60601-1-1:2001.
If in doubt, consult the technical service department or your local representative.

Autorefractor/Keratometer ERK-5400
1. Features
 Intended Use
The Auto Refractor/Keratometer ERK-5400 is used to determine the initial,
objective refractive values for a patient’s eye in the workflow of refraction to
determine the optical prescriptions for myopia, hyperopia and astigmatism.
 Various Measurements Supported
Not only the usual refractometry and keratometry, but also corneal diameter and
base curve of contact lens can be measured with this one instrument. Thus,
measurements of eye and prescriptions for glasses and contact lenses can be
made more efficiently.
 Wide Dioptric Measurement Range
Because the ERK-5400 covers a wide measurement range, from
-25D to +22D, even an examinee with strong myopia can be measured.
 More accurate Measurement
The fogging method of the eye fixation target makes examinee’s eye
comfortable and enables to get more accurate measurement data
 Simple and convenient user’s environment
Deliver more convenient user environment with wide viewed 7.0 COLOR LCD
screen and with simple and intimate design.
 Developed illumination
May observe eye condition of the cataract or contact lens surface with this
feature.
May observe whenever it sis necessary since save up to 2 images of each eye.
 Easy Connection with other Equipment
This instrument is designed to connect other Equipment such as LCD monitor.

Operation Manual
2. Notes for Using the Instrument
1. To avoid the risk of electric shock, this equipment as power protective earth
connection must be connected
2. Ensure that the examinee has not placed his/her hand or fingers under the
chin rest. Otherwise, hand or fingers may be hurt.
3. Do not hit or drop the instrument. The impact may cause damage to the
function of this instrument. Please handle with care.
4. Only operate the instrument with the power supply indicated on the rating
plate. Otherwise, it may result in fire or electric shock.
5.
Never disassemble or modify. This can cause fire or electric shock.
6. In case there is smoke, strange odor or noise during operation, disconnect the
power supply and consult the distributor.
7. For replacement parts (battery, fuse, or other parts), please contact the
distributor from whom you purchased the product.
8. The external connection device is used UL certificate device and the specified
power code, paper and fuse are used.
1. An exposure to the direct sunlight or too bright indoor lights may influence on
the result of accurate measurement. Appropriate Optometry room use.
2. A sudden heating of the room in cold areas will cause condensation on the
protective glass in the monitor screen and on optical parts inside the
instrument. In this case, just wait until condensation disappears before
performing measurement.
3. Keep the objective glass of the examinee side clean. If it was stained, it may
cause on ERROR or inaccurate measurements.
4. If you leave ERK-5400 without using for certain period, disconnect the power
supply and protect the unit with dust cover.
5. When moving this ERK-5400, fix the stage by using clamping bolt and stage
holding knob, always keep power off, and then lift the bottom of the unit with
both hands.
6. When moving this ERK-5400, do not hold forehead.
7. When moving and connect other device this ERK-5400, keep in touch with
qualified technician or service agent and place the equipment plain.
8. Get worked, store and move under the following environment conditions for
proper operation.

your fingers and measure again
When the pupil is smaller than the Outer
Alignment Mark.
The minimum pupil diameter that can be
measured is 2.0 mm. Although it is
possible to measure in the bright place,
don’t expose examinee’s eyes to the
direct sunlight or too bright indoor lights to
prevent the contraction of the pupil.
When the examinee has some illness

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. 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 ERK-5400 is used exceeds the
applicable RF compliance level above, the ERK-5400 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the ERK-5400.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.

Recommended separation distances between portable and
mobile RF communications equipment and the ERK-5400
The ERK-5400 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the ERK-5400 can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the ERK-5400
as recommended below, according to the maximum output power of the communications equipment.
