Notes on Storage
• The CM-3700A 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-3700A with a drying
agent at a temperature around 20°C.
• Do not leave the CM-3700A 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-3700A. This protects the
instrument from sudden changes in temperature, vibration, and shock.
• Do not store the CM-3700A 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-A156).
• Take care not to leave the CM-3700A 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.).
Notes on Cleaning
• If the CM-3700A becomes dirty, wipe it with a soft, clean dry cloth. Never use solvents such as thinner or
benzene.
• If the White Calibration Plate becomes dirty, wipe it with a soft, clean dry cloth. If dirt is difficult
to remove, wipe it off with a cloth dampened with commercially-available lens cleaning solution.
Then remove the solution with a cloth dampened with water, and leave the plate to dry.
• If the inner surface (white-coated surface) of the Target Masks, or the inside of the integrating sphere, get-
dirty, contact a Konica Minolta-authorized service facility.
• Should the CM-3700A break down, do not try to disassemble and repair it by yourself. Contact a Konica
Minolta-authorized service facility.
Disposal Method
• Make sure that the CM-3700A and its accessories and packing materials are either disposed of or recycled
correctly in accordance with local laws and regulations.
