Thank you for purchasing a CR-2000.
The CR-2000 is a quick charger for the nickel cadmium and nickel metal hydride battery used
in radio control transmitters, receivers, and glow boosters. Since this charger can charge the
battery faster than ordinary chargers for home use, that much more care is required.
To fully display the performance of the charger and to use the charger safely, please read this
instruction manual thoroughly before use.

Do not leave the side of the CR-2000 during charging. If you sense an abnormality at
the charger or battery during charging, immediately stop charging. If the temperature of
the battery rises to 60｡C or higher, it is extremely dangerous. If the battery suddenly
becomes hot, immediately stop charging.

•When a nickel cadmium or nickel metal hydride battery is new or has not been used for a long time,
the delta peak, which is the criteria for the end of charging, will be difficult to obtain and may not be
detected. If charging is continued, the battery will be overcharged and become abnormally hot and is
extremely dangerous.

Features of CR-2000

•Nickel cadmium and nickel metal hydride batteries for transmitter, receiver, and glow booster
can be charged.

Usage precautions

Do not use the charger near materials that may ignite.

•There is the danger of ignition by sparking when the battery is connected or disconnected.

Never charge a battery other than a nickel cadmium or nickel metal hydride battery.

•Charging a noncompliance battery will cause the battery to overheat or give off sparks and is
extremely dangerous.

Never connect the battery in reverse.

•Reverse connection will cause the battery to overheat or will damage the inside of the charger.

Do not add an additional charge after charging.

•Auto cut will not function and the battery will overcharge and overheat and is extremely dangerous.

Never get the charger wet.

•The interior of the charger is a precision electronic circuit and the entry of water will cause erroneous
operation. If the charger gets wet, always have it repaired.

Do not charge a warm battery.

•The specified charging amount cannot be obtained and the battery performance will not be amply
displayed. Charge the battery after it has cooled.

Never charge a battery over its nominal capacity (1C).

•If a battery is charged with a current exceeding 1C, the battery will overheat and deteriorate.

Do not connect two or more battery packs to one output terminal.

•It is extremely dangerous because the battery will short circuit and auto cut will not function normally.

When power is taken from a car, do not operate the car ignition switch during charging.
Also, do not charge the battery while the car is in motion.

•It will cause input voltage changes and erroneous operation due to vibration, etc. When an
abnormality occurs while running, it cannot be coped with and is associated with serious accidents.

Do not perform charging with the charger sitting on vinyl, plastic, or other materials that
melt easily or on a car seat or other flammable article.

•The charger will heat up during charging. Also, the battery may also overheat for some reason.

Do not contact the metal parts of a glow booster into other live parts during charging.

•Shorting is extremely dangerous.

Avoid places where the charger will be exposed to direct sunlight. Perform charging
within the 5~40°C range.

•Normal charging will be impossible and will cause abnormal heating.

When charging a new battery or a battery that has not been used for a long time, auto
cut may not function. If the battery becomes abnormally hot, stop charging.

•When a nickel cadmium or nickel metal hydride battery is new or has not been used for a long time,
the delta peak, which is the criteria for the end of charging, will be difficult to obtain and may not be
detected. If charging is continued, the battery will be overcharged and become abnormally hot and is
extremely dangerous. When the delta peak is not detected and auto cut does not function, it may be
possible to detect the delta peak by discharging and charging the battery 2~3 times using a standard
charging current charger.

Charge a battery that has been appropriately discharged.

•If a battery is repeatedly charged with a charge remaining, it may not return to its original
performance. The criteria for the charge remaining after discharge are 0.9V/cell.

Be careful that the cord is not pinched or shorted.

•If the cord is shorted, the battery may heat up and give off sparks.

During charging, check the charging amount at the data display screen. When the
charging amount becomes extremely large, stop charging.

•Auto cut may not function for some reason.

After the end of charging, disconnect the battery from the charger.

3 Starting and ending charging

Do not leave the side while charging. If you notice an abnormality at the charger or
battery during charging, immediately stop charging. If the battery temperature rises to
60˚C or higher, it is extremely dangerous. If the battery suddenly becomes hot,
immediately stop charging.

•When a nickel cadmium or nickel metal hydride battery is new or has not been used for a long time,
the delta peak, which is the criteria for the end of charging, will be difficult to obtain and may not be
detected. If charging is continued, the battery will be overcharged and become abnormally hot and is
extremely dangerous.

When taking power from a car, do not operate the ignition key during charging. Also, do
not charge while the car is in motion.

•It will cause input voltage changes and erroneous operation due to vibration, etc. when an
abnormality occurs while running, it cannot be coped with and is associated with serious accidents.

When the START button is pressed, charging starts. At this time, the "CHG" LED lights. Also,
after the start screen is displayed for about 5 seconds, the display switches to the data display
screen and the charging state can be monitored.

[When starting charging]

When a battery is connected, the charger
automatically checks the battery. When the
START button is pressed immediately after
connection, an error may be displayed,
depending on the state of the battery. In this case,
reset the error display by pressing the CURRENT
button. After the data display screen output
voltage display rises to about 10V, start charging
by pressing the START button.

Always check the charging current at the current
setting screen before starting charging. Set the
charging current to the nominal capacity (1C) or
less of the battery. For example, for a 600mAH
battery set the charging current to 0.6A or less.

At the end of charging, check the peak voltage, charging amount, and
other data and that the battery is about body temperature, and then
disconnect the battery from the charger.

[Charging current after auto cut]

After auto cut, the charger automatically switches
to a low charging current and continues charging.
The charging current value after auto cut varies,
depending on the charging current set value.

Charging current set value 0.05-0.45A 0.5-2.5A

Charging current after auto cut 5mA 70mA

(Forced end)

When the START button is pressed when you want to forcibly end charging midway, charging
ends. At this time, the display switches to the data display screen about 5 seconds after an
audible alarm (beep beep beep beep, beep beep beep beep, beep beep beep beep) sounds and
the forced end screen appears. The "CHG" LED goes off.
