• Use the CM-5 at an ambient temperature between 13°C and 33°C and relative humidity 80% or less (at 35°C)
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 CM-5 in direct sunlight or near sources of heat, such as stoves etc. The internal temperature
of the instrument may become much higher than the ambient temperature in such cases.
• Do not use the CM-5 in areas where dust, cigarette smoke or chemical gases are present. Doing so may cause
deterioration in performance or a breakdown.
• Do not use the CM-5 near equipment which produces a strong magnetic eld (such as speakers etc.).
• The CM-5 belongs to installation category I products (equipment which is powered by an AC adapter
connected to commercially available power).
• The CM-5 belongs to pollution level 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-5 at altitudes higher than 2,000 m.
• The CM-5 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.
• Use a blower to remove dust and dirt from the shutter before using the instrument after a long period of
disuse.
• 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 Cap.
White Calibration Plate
There are two types of white calibration plate for use with this instrument: the built-in White Calibration Plate
inside the shutter and an external White Calibration Plate as an optional accessory.
• 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 (optional accessory) to get scratched or stained, or get ngerprints on
it.
• When the White Calibration Plate (optional accessory) is not in use, be sure to close the cap so that the White
Calibration Plate is not exposed to ambient light.
Target Mask
There are three types of Target Masks for use with this instrument: the standard ø30 mm mask, and optional ø3
mm and ø8 mm masks.
• The ø30 mm Target Mask must be used in combination with the instrument that bears the same pairing
number.
• Do not touch the Target Mask's inner surface by hand, scratch it or make it dirty.
• When not in use, Target Masks should be stored in the packing used for shipment or in the optional accessory
case so that they will not be exposed to ambient light.

E3
Power Source
• Make sure that the power switch is set to OFF (“”) when the CM-5 is not in use.
• This instrument can be powered from the AC adapter (AC-A305).
• Always use the AC adapter supplied as a standard accessory (AC-A305) 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 re.
System
• Do not subject the CM-5 to strong impact or vibration.Doing so may cause deterioration in performance or a
breakdown.
• Since the specimen measuring port and integrating sphere are extremely precise optical components, great
care should be taken to prevent them getting dirty or exposing them to impact.
• The CM-5 may cause interference if used near a television, radio, etc.
• When the instrument is exposed to strong external static electricity, the LCD may go blank or the
measurement result may not be displayed properly. If the instrument is communicating with an external
device, the communication may be interrupted. In these cases, turn the power OFF and then turn it ON again.
If black smudges appear on the LCD, wait until they disappear naturally.
• When turning the power OFF and then ON again, wait several seconds after turning the power OFF.
Backup Battery
• Measured data and various settings are stored in the memory backed up by batteries. The backup batteries are
automatically charged during operation of this instrument, and can retain the contents of the memory for three
months if they have been fully charged. At the time of purchase, the backup battery may not be fully charged.
To charge the backup battery, set the power switch to ON. The backup battery is fully charged in 72 hours
while the instrument is switched on, and there is no danger of overcharging.
• It is recommended to keep a backup of your important data on another recording medium using the optional
Color Management Software SpectraMagic™ NX (CM-S100w).

Notes on Storage
• The CM-5 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-5 with a drying agent at a temperature around
20°C.
• Do not leave the CM-5 inside a car such as in the cabinet or 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-5. This protects the
instrument from sudden changes in temperature, vibration, and shock.
• Do not store the CM-5 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 specimen chamber and cover the instrument with the supplied Dust
Cover to prevent the entry of dust into the integrating sphere.
• The White Calibration Plate (optional accessory) may become discolored if left exposed to light. Therefore,
make sure to close the cap 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.
• 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-5 becomes dirty, wipe it with a soft, clean dry cloth.Never use solvents such as thinner or benzene.
• If the White Calibration Plate (optional accessory) becomes dirty, wipe it with a soft, clean dry cloth.If dirt is
difcult 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 of the Target Masks, the inside of the integrating sphere , or the built-in White Calibration
Plate get dirty, contact a KONICA MINOLTA-authorized service facility.
