Introduction
The MYIRO-1 is a compact, lightweight hand-held spectrophotometer
designed for measuring color and density in the printing and digital imaging
industries with just one device.
Packing materials of the productBe sure to keep all packing materials used for shipping the product(cardboard box, cushioning material, plastic bags, etc.). This instrument is a
precision measuring instrument. When transporting the instrument to aservice facility for maintenance or for other reasons, be sure to use thepacking materials to minimize shock or vibration. If the packing materials
are lost or damaged, contact your retailer.

Notes on Use
Operating Environment• Use the instrument at an ambient temperature of between 10°C and 35°C
and a relative humidity of between 30% and 85% with no condensation.
• Be sure to use the instrument within this range. Do not use it in areas of rapid
temperature changes.
• Do not leave the instrument in direct sunlight or near heat sources such as astove. Doing so may cause the internal temperature of the instrument tobecome much higher than the ambient temperature.
• Do not use the instrument in areas where dust, cigarette smoke, or chemicalgases are present. Doing so may cause deterioration in performance or amalfunction.
• Do not use the instrument near equipment that produces a strong magnetic
field (such as speakers).
• The instrument is a pollution level 2 product (equipment that may cause
temporary electrical hazards due to contamination or condensation or
products that are used in such an environment).
• Do not use the instrument at altitudes higher than 2,000 m.
• This instrument has been designed exclusively for indoor use. It should
never be used outdoors because rain or other factors may damage theinstrument.

5

Measurement• Make sure no dust gets into the instrument ports.
• When not using the instrument for a long period of time, remove the limiting
aperture, and blow off dirt or dust on the protection glass with a blower
before use.
• Over extended periods of use, changes in the surrounding environment may
result in the measured values shifting. Performing calibration periodically isrecommended to ensure measurements are accurate.

White Calibration Plate• Make sure the white calibration plate being used includes the same serial
number as that of the instrument being used.
• The calibration data for the white calibration plate was measured at 23°C.
• To achieve the highest accuracy when measuring absolute values(colorimetric values), calibration and measurement should be performed at
23°C.
• Do not allow the white calibration plate to become scratched or dirty.
• When the calibration cap is not in use, keep the white calibration plate awayfrom external light and dust.

Ruler• The sliding surface has a special coating that facilitates sliding. If there isdust or dirt on the ruler, use a blower to blow it off or gently wipe it with asoft, clean dry cloth. Never use solvents such as thinner or naphtha.

6

Ambient Light Adapter• Make sure the ambient light adapter being used includes the same pairing
number as that of the instrument being used.
• Do not allow the ambient light adapter to become scratched or dirty.
• Keep the ambient light adapter away from external light and dust when not
in use.

Power Source• When the instrument is not being used, turn the power switch OFF.
• To charge the instrument, connect it to a computer using the USB cable.

System• Do not subject the instrument to strong vibrations or impacts. Doing so may
cause deterioration in performance or a malfunction.
• The limiting aperture (measuring port) of this instrument is a particularly
precise component of the optical system. Do not allow the aperture to
become dirty or subject the aperture to impacts. When the instrument is not
in use, make sure to attach the calibration cap to protect the limiting
aperture (measuring port).
• The instrument may cause interference if used near a television, radio,transceivers, etc.

• When turning the power OFF and then ON again, wait several seconds after
turning the power OFF before turning the power back ON.

7

Internal Lithium-Ion Battery• The battery is not charged upon purchase and must therefore be charged.
• The battery will be charged from power supplied through the USB cable
regardless of whether the instrument is turned ON or OFF.
• Charging should be performed at between 5°C and 40°C.
• The internal lithium-ion battery takes about 3 hours to become fully charged.
There is no need to worry about overcharging.
• The lithium-ion battery will self-discharge. The battery will become unusable
due to over discharging if left for a long period. Charge the battery at least
once every 6 months.

Notes on Storage• The instrument should be stored at a temperature of between 0°C and 45°C
and a relative humidity of between 0% and 85% with no condensation.
Do not store the instrument in areas subject to high temperatures, highhumidity, or sudden changes in temperature, or in areas where freezing orcondensation may occur, as these circumstances may cause a malfunction.
We recommended storing the instrument with a drying agent at atemperature of around 20°C.
• Do not leave the instrument inside a vehicle, such as in the cabin or thetrunk. Otherwise, the temperature and/or humidity may exceed theallowable range for storage during midsummer or midwinter, resulting in amalfunction.
• Do not store the instrument in areas where dust, cigarette smoke, or
chemical gases are present. Doing so may cause deterioration in
performance or a malfunction.
• Dust inside the limiting aperture (measuring port) may prevent accurate
measurements from being performed. When the instrument is not in use,
attach the calibration cap, and store the instrument in the standard
accessory soft case.
• The white calibration plate and ambient light adapter may become
discolored if left exposed to light. Therefore, make sure to store thecomponents in a location away from direct exposure to light when not in use.
• If the instrument will not be used for a long period of time, an auxiliary
charge is recommended once a year to protect the battery fromoverdischarge.

8

Notes on Transporting• When transporting the instrument, be sure to use the packing materials tominimize shock or vibration.
• When sending the instrument to your retailer, package and send the
instrument and all accessories.

Maintenance and Inspection• To maintain measurement accuracy, the instrument should be inspectedonce a year. For information on inspection, contact your retailer.

Notes on Cleaning• When the instrument is dirty, wipe it with a soft, clean dry cloth. Never use
solvents such as thinner or naphtha.
• If the white calibration plate becomes dirty, wipe it with a soft, clean dry
cloth. If the dirt is difficult to remove, wipe it off with a cloth dampened withcommercially available lens cleaning solution, remove the solution with acloth dampened with water, and allow the plate to dry before using.
