connected to commercially available power).
• The CM-3600A belongs to pollution degree 2 products (equipment which may cause temporary electrical
hazards due to contamination or condensation or products which are used in such an environment).
• Do not use the CM-3600A at altitudes higher than 2,000 m.
• The CM-3600A and the AC adapter supplied as a standard accessory have been designed exclusively for
indoor use. They should never be used outdoors because rain or other factors may damage the instrument.
Measurement
• Make sure no dirt or dust get into the specimen measuring port.
• When using the instrument for long periods of time, the measurement value may change depending on
changes in the environment. Therefore, in order to achieve accurate measurements, we recommend that
white calibration be done regularly using the White Calibration Plate.
White Calibration Plate
• 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 get scratched or stained with such as fingerprints.
• Do not move the White Calibration Plate while it has been caught by the sample holder. Doing so may
damage the White Calibration Plate.
• When the White Calibration Plate is not in use, be sure to close the cover so that the White Calibration
Plate is not exposed to ambient light.
Target Mask
• Do not touch the Target Mask's inner surface (black-coated surface) by hand, scratch it or make it dirty.
• When not in use, Target Masks should be stored in the accessory case (CM-A215) so that they will not be
exposed to ambient light.
Power Source
• Make sure that the power switch is set to OFF (" I ") when the CM-3600A is not in use.
• Always use the AC adapter supplied as a standard accessory (AC-A308) and connect it to an AC outlet of
the rated voltage and frequency.
• Use an AC power supply of the rated supply voltage (within ±10%).
• Do not connect the AC adapter to an overloaded electrical circuit. In addition, do not wrap or cover the AC
adapter with cloth or other material while in use. Doing so may cause an electric shock or fire.

⿎Notes on Storage
• The CM-3600A should be stored at temperatures between 0°C and 40°C, and at a relative humidity of 80%
or less (35°C) without condensation. Do not store the instrument in areas subject to high temperatures,
high humidity, sudden changes in temperature, or where freezing or condensation may occur, because
these circumstances may cause a breakdown. It is recommended to store the CM-3600A with a drying
agent at a temperature around 20°C.
• Do not leave the CM-3600A inside a car such as in the trunk. Otherwise, the temperature and/or humidity
may exceed the allowable range for storage during midsummer or midwinter, resulting in a breakdown.
• Keep the packing materials used for shipment and use them to transport the CM-3600A. This protects the
instrument from sudden changes in temperature, vibration, and shock.
• Do not store the CM-3600A in areas where dust, cigarette smoke or chemical gases are present. Doing so
may cause deterioration in performance or a breakdown.
• Entry of dust into the specimen measuring port will hinder accurate measurement. When the instrument
is not in use, you must close the transmittance chamber cover and cover the instrument with the supplied
Dust Cover to prevent the entry of dust into the integrating sphere.
• The White Calibration Plate may become discolored if left exposed to light. Therefore, make sure to close
the cover when it is not in use so that the White Calibration Plate is not exposed to ambient light during
storage.
• The Target Masks may discolor if they are left exposed to light. When they are not in use, keep them in a
safe place to prevent exposure to light and to protect them from scratches and dust. And store them in the
accessory case (CM-A215).
• Take care not to leave the CM-3600A for a long period of time with a target mask attached. The sample
holder may stick to the target mask.
• Be sure to keep all packing materials (cardboard box, cushioning material, plastic bags, etc.). They can be
used to protect the instrument during transportation to the service facility for maintenance (re-calibration
etc.).
⿎Notes on Cleaning
• If the CM-3600A becomes dirty, wipe it with a soft, clean dry cloth. Never use solvents such as thinner or
benzene.
