CAUTION 1. Intended use
Use the MW50D only for ophthalmic observation and microphotography
purposes. Do not use this instrument for any other purpose.
CAUTION 2. Do not disassemble
Disassembling this instrument may lead to electric shock and/or malfunction of
the instrument. Never disassemble this instrument.
CAUTION 3. Precautions to take when installing or carrying the instrument
・Always rest the instrument on a stable surface. Do not put it on a tilted surface.
The instrument may fall or drop and cause personal injury.
・Recommended operating conditions are as follows: barometric pressure 700 to
1060 hPa; ambient temperature 10 to 40ºC; and humidity 30 to 90%.
・This instrument complies with the EMC standards (IEC60601-1-2:2014).
However, it emits weak radio waves. This means that the instrument may
cause interference with radio communications. If this instrument does cause
interference with radio or television reception, try to increase the distance
between the instrument and the device that is receiving the interference, or
reorient the instrument.
・Remember that this instrument is not water-proof. Do not ever use or install it in
a location where exposure to liquids (such as rainwater, drinks, chemicals) may
occur.
・If condensation (dew) forms, do not use the instrument until the condensation
disappears.
・When carrying this instrument, remove the cable from the power supply unit,
and carry it by holding the base of the instrument. Holding or lifting it at a point
somewhere other than the base may damage the instrument.
・In case of installation of the main unit and accessories, options, be performed
by the trained service personnel always.
6
CAUTION 4. Precautions to take before and during observation
・When positioning a patient’s head in the main unit, use caution not to allow any
moving parts of the instrument to hit the person’s face while preparing the
instrument for observation. Preparations include adjustment of the observation
position, focus, observation and illumination angles, etc.
・Do not use the instrument in a dusty room.
・The best place to install the instrument is in a dimly-lit room. Do not have the
patient’s side of the instrument face a bright window or a light source. This may
adversely affect observations.
・Replace the lamp bulb with a new one when the bulb starts to dim. Insufficient
light may lead to improper observations.
・The eyesight of the patient may be temporarily impaired after an examination
because of the intense light used. Allow the patient to rest a while after an
examination, until the patient’s eyesight returns to normal.
・Do not use an excessive amount of light during an examination, to avoid placing
an unnecessary burden on the patient. Improper illumination intensity may
prevent correct observations.
・Allow a patient who has trouble viewing stereoscopically or one who squints to
wear their prescription lenses. A patient whose diopter correction is ±8D or
more will also need the correction offered by their glasses.
・Be careful not to pinch your fingers between the moving parts of the instrument
during observation.
・Keep other people away from the instrument during an examination. The patient
may be distracted, resulting in incorrect results.

CAUTION 5. Precautions to the light hazard
Because prolonged intense light exposure can damage the retina, the use of the
device for observation should not be unnecessarily prolonged, and the brightness
setting should not exceed what is needed to provide clear visualization of the
target structures. This device should be used with filters that eliminate UV
radiation (< 400 nm) and, whenever possible, filters that eliminate
short-wavelength blue light (<420 nm).
The retinal exposure dose for the light hazard is a product of the radiance and the
exposure time. If the value of radiance were reduced in half, twice the time would
be needed to reach the maximum exposure limit.
While no acute optical radiation hazards have been identified for slit lamps, it is
recommended that the intensity of light directed into the patient’s eye be
limited to the minimum level which is necessary for diagnosis.
Infants, senior citizens, aphakes and persons with diseased eyes will be at greater
risk.
The risk may also be increased if the person being examined has had any
exposure with the same device or any other ophthalmic device using a visible
light source during the previous 24 hours. This will apply particularly if the eye
has been exposed to retinal photography.
CAUTION 6. Other precautions to take during handling
・When positioning a patient’s head in the main unit, use caution not to allow any
moving parts of the instrument to hit the person’s face while preparing the
instrument for observation. Preparations include adjustment of the observation
position, focus, observation and illumination angles, etc.
・Do not scratch, break or alter the power cord, or overly bend, pull, twist or bundle
it. Also, placing heavy object on the power cord or subjecting it to heat may cause
it to break, resulting in fire or electric shock. If the power cord becomes damaged,
replace it with a new one.
・Do not connect or disconnect the power cord with a wet hand.
・If there is any dust on the power plug blades or the surface they connect to, pull
out the power plug and remove the dust. The dust or grime can make the power
plug and AC power outlet to be out of contact and may result in fire.
・Connect the power supply unit to a grounded electric outlet that meets the power
supply requirements of the unit. Failure to do so may affect the performance of
the instrument adversely or result in malfunction of the instrument, electrical

5-7. Zero-Position Adjustment of the Slit Width Adjustment Knob
If there is any difference between the scale on the slit width adjustment knob and the
actual slit length, use the following procedure to adjust the zero position of the slit
width adjustment knob.
(1) While observing through the eyepiece lens, turn the slit width adjustment knob
clockwise and stop when the slit is fully closed.
(2) Loosen the slotted screw (located between the seals on the knob bottom) on the
scale ring to set the scale ring free.
Turn the scale ring until the “0” index on the seal on the scale ring is in alignment with
the reference index and tighten the slotted screw you loosened in step (2).
Never turn the slit width adjustment knob counterclockwise.
Do not turn the slit width adjustment knob at this moment.
Do not turn the slit width adjustment knob at this moment.

(3) Turn the slit width adjustment knob one turn clockwise and make sure that the
slit is closed when the index line is set to “0”. Repeat steps (1) to (3) if the slit is not
closed.
5-8. If the Slit Width Gets Narrower During Observation:
The problem of the slit width becoming narrower during observation can occur if the
slotted screw in the center of the slit width adjustment knob has become loose.
Turn this screw clockwise a little with an Allen wrench (Hex-head wrench).
● Excessive tightening of the slotted screw clockwise will make the movement of the
slit width adjustment knob slower.
● Do not turn the slotted screw fully counterclockwise. The screw will come off. Once
this screw is removed, you may have to call your dealer for repair.
