Backup Battery; Power Source - Konica Minolta CM-25cG Instruction Manual

• When turning the power OFF and then ON again, wait several seconds after turning the power OFF before
turning the power ON again.
• The instrument should be connected to a power source with as little noise as possible.
• When a malfunction or abnormal behavior occurs, turn the power OFF immediately, disconnect the AC adapter
plug from the AC outlet, and refer to "Troubleshooting" on page 119.
• Should the instrument break down, do not try to disassemble and repair the instrument. Contact a KONICA
MINOLTA-authorized service facility.

Backup Battery

• Various settings are stored in the instrument's built-in battery-powered backup memory. The backup battery
will be charged when the instrument is powered or when the lithium-ion battery is being charged, regardless of
whether the power switch is turned ON/OFF. The backup battery takes 20 hours to become fully charged, and
there is no danger of overcharging. At full charge, the backup battery can store data for up to one year.
However, the backup battery may not be fully charged when the instrument is purchased. The backup battery
will charge as the instrument is being used.
• Do not attempt to replace the built-in backup battery. The battery should only be replaced by KONICA
MINOLTA. To replace the backup battery, please contact a KONICA MINOLTA-authorized service facility.
• It is recommended to manage important data using the optional SpectraMagic DX software.
Calibration Plate
• The calibration data for the calibration plate was measured at 23°C. To achieve the highest accuracy when
measuring absolute values, calibration and measurement should be performed at 23°C.
• Do not allow the calibration plate to become scratched or dirty.
• When the calibration plate is not in use, be sure to close the cap so that the plate is not exposed to light.

Power Source

• Make sure that the power is turned OFF when the instrument is not in use.
• This instrument should be used with the lithium-ion battery installed. You cannot use the instrument connected
to the AC adapter only.
• Make sure the AC adapter output plug is not short-circuited. Doing so may cause a fire or electric shock.
• 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.
• When removing the AC adapter from the instrument, first remove the power cord from the outlet, and then
remove the output plug.
Battery
• Use only the standard lithium-ion battery or the optional accessory lithium-ion battery CM-A235 (RRC1120).
Absolutely do not use any other type of battery.
• The battery in the instrument will be charged from the power supplied through the USB cable regardless of
whether the instrument is turned ON or OFF.
• The battery is not charged upon purchase and must therefore be charged.
• The battery takes about 6 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 for at least one hour using the instrument or an optional battery charger at
least semiannually.
• After using up the lithium-ion battery, do not leave it uncharged.
• Charging should be performed at between 5 and 40°C. Charging will not be performed outside this
temperature range.
• If the lithium-ion battery will not be used for a long period, remove the battery from the instrument and store it
in a location not subject to high temperatures or high humidity.
