Notes on Use
<Operating Environment>
• This instrument and the AC adapter supplied as a standard accessory have been designed exclu-
sively for indoor use.
• Do not leave the CR-400/410 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 CR-400/410 in areas where dust, cigarette smoke, or chemical gases are present.
Doing so may cause deterioration in performance or breakdown.
• Do not use the CR-400/410 near equipment which produces a strong magnetic field (such as speak-
ers, etc.)
• The CR-400/410 is classified as an Installation Category II (equipment which is powered by an AC
adapter connected to a commercially available power source).
• The CR-400/410 is classified as a Pollution Degree 2 (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 CR-400/410 at altitudes of higher than 2000m.
• Use this instrument at ambient temperature between 0 and 40ºC and relative humidity 85% or less
(at 35ºC) with no condensation (*1). The instrument may not satisfy design performance, if used
outside the working temperature and humidity ranges. Operating this instrument outside specified
temperature and humidity range may unsatisfy its original performance.
*1 Operating temperature/humidity range of products for North America: between 5 and 40ºC and relative humid-
ity 80% or less (at 31ºC) with no condensation
<The Instrument>
• Do not subject the CR-400/410 to strong impact or vibration.
Doing so may cause deterioration in performance or breakdown.
• The measurement aperture should be protected from dirt and strong impacts. Always attach the
protective cap when not in use.
• The CR-400/410 may cause interference if used near a television, radio, etc.
• Due to the effect of electrostatic discharge on or in the vicinity of CR-400, erroneous can occur. In
this cace please repeat the last mesurement. If strong static electricity is received at the moment
measurement is made, the measurement values may be adversely affected, but the following mea-
surement will be ok.
<Measurement>
• When using the Measuring Head upside-down, make sure no dirt or dust get into the aperture.
• 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 recom-
mend that white calibration be done regularly using the white calibration plate. Doing this will
automatically correct other calibration channels, so there is no need to calibrate them.
• Changes in the temperature will cause the color of the specimen to change, resulting in changes in
the measurement data even if white calibration has been done. Therefore, calibration, setting of
color difference target colors, and measurement should all be done at the same temperature.
• When performing continuous measurements, remove the batteries and use the AC adapter.
<Displayed Data>
• Although this instrument is designed for increased accuracy in operations by internally calculating
more digits than are actually displayed, some operation errors may occur in the minimum number of
digits during rounding off, color space conversion, and in other situations.
<White Calibration Plate>
• The white calibration plate is placed near the middle. When doing a calibration, use the area near the
middle.
• Do not allow the white calibration plate to get scratched or stained.

5
• If you are not going to use the white calibration plate, close the cover to the white calibration plate
to prevent entry of ambient light, as any areas exposed to such light will discolor.
<Roll Paper>
• This roll paper is special paper (thermal paper) which displays color as the result of a heat-induced
chemical reaction.
• Do not store in hot and/or humid places.
• Do not expose to direct sunlight, fluorescent light, or other outside light for long periods of time.
• Using roll paper which has become discolored because of the way it was stored will result in print-
ing which is difficult to read. Use new roll paper whenever possible.
• Printed data may become illegible because of storage conditions, therefore it is recommended to
copy data intended for long-term storage immediately after it has been printed.
<Printing>
• Since the printer uses a thermal mechanism, the ambient temperature may affect the speed and/or
consistency of print.
<Power Source>
• Do not short-circuit the output plug of the AC adapter. Doing so may cause fire or electric shock.
• The AC adapter is an EMC Class B device. If used in a home environment, it may cause electrical
interference. This may require the user to take suitable countermeasures.
• Make sure that the power switch is set to OFF when the CR-400/410 is not in use.
• Use only the AC adapter (AC-A305) included with the product and connect it to a 100V AC (50/60
Hz) electrical outlet. Do not use other AC adapters for any reason whatsoever.
• Use an AC power source which is within 10% of the rated voltage.
• Do not connect the AC adapter to electrical strips or other connection devices that share the power
supply. Also, do not cover or wrap the AC adapter with cloth and the like during use. Doing so may
cause fire or electric shock.
• In the event of trouble, disconnect the power cable from the AC adapter terminal on the instrument.
Do not install the instrument anywhere that makes it difficult to disconnect the power cable from the
AC adapter terminal on the instrument, in an emergency.
• Do not use the instrument anywhere it can get wet. Contact with water may cause fire or electric
shock.
• When disconnecting the AC adapter from the instrument, first disconnect the power cable from the
electrical outlet and then disconnect the power cable from the AC adapter terminal on the instru-
ment.
<Recommended Batteries>
• A low ambient temperature will cause a drop in battery performance, with similar results for perfor-
mance in terms of number of measurements and printing speed and consistency. We therefore rec-
ommend you use lithium or nickel metal-hydride batteries which can withstand changes in tem-
perature.
<Backup Batteries>
•Measurement data and settings are stored in memory which is backed up by the internal backup
batteries. The backup batteries are automatically charged during operation of the instrument, and
can retain the contents of memory for 10 months if they have been fully charged. At time of pur-
chase, the batteries may have already been partially discharged, so turn the power on to charge
them. Charging of the backup batteries is performed continuously while the instrument is switched
on, even while the instrument is being used. The batteries can be fully charged about 20 hours, and
there is no danger of overcharging.
• Do not replace the internal backup batteries (type: ML2020 3V) yourself. Contact the nearest Konica
Minolta authorized service facility to replace the backup batteries.
• We recommend that you backup all important data and store it separately.

6
Notes on Storage
• The CR-400/410 should be stored at temperatures between -20 and 40 ˚C and a maximum relative
humidity of 85%. Do not store it in areas subject to high temperatures, high humidity, or rapid
changes of temperature, or where condensation may occur. For added safety, we recommend that it
is stored with a drying agent at room temperature.
• Do not leave the CR-400/410 inside a car or in the trunk of a car. Under direct sunlight in summer,
the increase in temperature can be extreme and may result in malfunction.
• Do not store the CR-400/410 in areas where dust, cigarette smoke, or chemical gases are present.
Doing so may cause deterioration in performance or breakdown.
• When not using the white calibration plate, close the cover and store it.
• Do not throw away the packing materials (cardboard box, cushioning material, plastic bags, etc.).
They can be used to protect the instrument during transportation to a service facility for mainte-
nance (re-calibration etc.).
• If you are not going to be using the CR-400/410 for more than two weeks, the batteries must be
removed. If the batteries are left in the instrument, leakage may occur resulting in damage to the
instrument.
Notes on Cleaning
• If the CR-400/410 becomes dirty, wipe it with a soft, clean dry cloth. Never use solvents such as
thinner and benzene.
• If the white calibration plate becomes dirty, wipe it gently with a soft, clean dry cloth. If dirt is
difficult to remove, wipe it with lens cleaner and cloth, then dry.
• If the CR-400/410 break down, do not try to disassemble and repair it by yourself. Contact a Konica
Minolta authorized service facility.
Notes on Disposal
• Dispose of this instrument, accessories and packaging materials in line with local waste codes.
