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.
Features of CR-2000
•Nickel cadmium and nickel metal hydride batteries for transmitter, receiver, and glow booster
can be charged.
•Auto cut by peak voltage detection
•Transmitter and receiver batteries or transmitter and glow booster batteries can be charged
simultaneously.
•The charging current can be changed. Transmitter: 0.5A~2.0A (0.1A steps), receiver:
0.05A~2.0A (0.05A steps), glow booster: 1A~2.5A (0.5A steps)
•The input voltage, output voltage, charging current, peak voltage, charging time, and
charging amount can be monitored on an LCD display.
CR-2000 Ratings
•Input voltage:
DC11V~15V (low battery display at 10.5V)
•Corresponding batteries:
TX: 500~2,000mAh (6~8 cells)

[Accessories]
The following charging cords (3 types) are supplied with the CR-2000 set. Use these cords
when charging a battery mounted in the fuselage and when charging the battery by
connecting the charger to the charging jack of a transmitter.
Input clip (black)
Cigarette socket
Input clip (red)
*TX and RX or TX and GLOW can be charged simultaneously.
*RX output and GLOW output cannot be used simultaneously. Only the
GLOW side is effective even if a battery is connected to both outputs.
Charging adapter (200cm)
Use when connecting the charger to a battery, etc. mounted
in the fuselage.
TX charging adapter (70cm)
Use when connecting the charger to the charging jack of
a transmitter.
Charging adapter (50cm)
Use when connecting the charger to a battery, etc. mounted
in the fuselage.
(While pressing the side wall)
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.
Meaning of Special Markings
Pay special attention to safety where indicated by the following marks:
Procedures which may lead to dangerous conditions and cause death/serious injury
if not carried out properly.
Procedures which may lead to a dangerous condition or cause death or serious
injury to the user if not carried out properly, or procedures where the probability of
superficial injury or physical damage is high.
Procedures where the possibility of serious injury to the user is small, but there is a
danger of injury, or physical damage, if not carried out properly.
: Prohibited : Mandatory
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.
Do not use the accessory TX
charging adapter (transmitter
extension cord) with other makes
of transmitter. This extension cord
is designed to be used with
Futaba transmitters only.
•The polarity (+, -) of the transmitter
charging jack may be different.
Do not modify the accessory
charging adapter (extension cord).
•If shorted or connected in reverse, the
CR-2000 or the battery will be abnormally
heated and damaged.
