Changing operational mode and its data screen (TX/RX/GLOW)
When a battery is connected to any one of the TX, RX and GLOW terminals, the CR-2500 charger automatically detects
its mode and displays the data of the battery. And each button will become operational. But if you want to change the mode
while one or two outputs are connected, you can change the mode manually by pushing SELECT button. Every time you
push the SELECT button, the mode changes to TX->RX-CHG->RX-DISCHG->RX-CYCLECHG->GLOW->TX.

Charging Current Setting (RX/GLOW)
Check the charging current on the current setting screen first. If necessary to change the charging current, turn the
SELECT dial while this screen is being displayed. Even if the current setting screen is closed, you can recall it by pushing
the CURRENT button.
5
Start and end each mode (TX/RX/GLOW)
The followings are descriptions about how to start or end each mode. RX has three modes, which are Charging,
Discharging and Cycle modes. In order to change from the mode currently under operation to another mode, stop the
current mode by pushing the START button and then change the mode.
TX CHARGE MODE
While TX LED is lit red, the charger is in TX charge mode. Charging current is automatically set and cannot be changed.
When you push the START button, the "CHG" LED turns on and the charging starts automatically. You can monitor the
charging status on the data screen after about 5 seconds of START screen. The charging current will gradually decrease as
the charging progresses. When the charging reaches 90% of the capacity, the end-alarm beeps and one-hour charging timer
starts. Then, LCD display starts showing "TIMER CHARGING" screen and normal data screen alternatively. (The display
shows the remaining time and the accumulated time alternatively during the timer charging.)
As the timer-charging is a sort of very tiny current charging, and more than 90% of the battery capacity has been charged,
the battery can be said to be ready for use. CHG LED is off during timer charging.
RX CHARGE MODE
While RX LED is lit red, the charger is in RX charge mode. After confirming the charging current on the current setting
screen, push the START button, then the "CHG" LED turns on and the charging starts. You can monitor the charging status
on the data screen after about 5 seconds of START screen. When charging is completed, the end screen appears with the
alarm sound (beep-beep-beep-beep, beep-beep-beep-beep, beep-beep-beep-beep). Then, the end screen switches to the
data screen 5 seconds later. The "CHG" LED is off.
RX DISCHARGE MODE
While RX LED lit blue, the charger is in RX discharge mode. The charging current is fixed to 0.5A, and it cannot be
changed. Push the START button, then the "CHG" LED blinks and starts discharging. You can monitor the discharging
status on the data screen after about 5 seconds of START screen. When discharging is completed, the end screen appears
with the alarm sound (beep-beep-beep-beep, beep-beep-beep-beep, beep-beep-beep-beep). Then, the end screen switches
to the data screen 5 seconds later. The "CHG" LED is off.
GLOW CHARGE MODE
When GLOW LED is lit orange, the charger is in the GLOW charge mode. Check the charging current on the current
setting screen, then push START button to start charging. The "CHG" LED turns on and the charging starts. You can
monitor the charging status on the data screen after about 5 seconds of START screen. When charging is completed, the
end screen appears with the alarm sound (beep-beep-beep-beep, beep-beep-beep-beep, beep-beep-beep-beep). Then, the
end screen switches to the data screen 5 seconds later. The "CHG" LED is off.
FORCED END
When you want to forcibly end charging or discharging midway, push the START button, then charging will stop. At this
time, the display switches to the data screen about 5 seconds after an audible alarm sounds (beep-beep-beep-beep, beep-
beep-beep-beep, beep-beep-beep-beep) and the FORCED END screen appears. "CHG" LED is off.
RX CYCLE MODE (RX Discharge-to-Charge mode)
When the RX LED is showing blue and red alternatively, the charger is in the Discharge-to-Charge mode. The charging
current is fixed to 0.5A, and it cannot be changed. Push START button, then the "CHG" LED blinks and starts discharging.
You can monitor the discharging status on the data screen after about 5 seconds of START screen. The discharging ends
with the alarm sound (beep-beep-beep-beep, beep-beep-beep-beep, beep-beep-beep-beep). Immediately after discharging
is completed, charging starts with the charging current set by this mode. Setting of the charging current is the same as RX
CHARG MODE. The "CHG" LED is on during the charging. When charging is completed, the end screen appears with the
alarm sound (beep-beep-beep-beep, beep-beep-beep-beep, beep-beep-beep-beep). Then, the end screen switches to the
data screen 5 seconds later. The "CHG" LED is off.
<When requesting repair>
Before requesting repair, read this instruction manual again and check the charger. When there is an
abnormality, request repair to your local Futaba dealer.

Power supply connection
When the input cable is connected to the 12VDC power supply and the
power is turned on, the CR-2500 automatically starts and the opening
screen will pop up.
(For about 2 seconds indication)
*After the opening screen being displayed, the TX data screen will appear.
Red
Connect to the + output of
the parent power supply. Connect to the - output of
the parent power supply.
Black
Do not leave the side while charging. If you notice any abnormality of 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 taking power from a car, do not operate the ignition key during charging. Also, do not
charge while the car is in motion.
•Otherwise, it may cause input voltage fluctuations and malfunctions due to vibration, etc. If an abnormality
occurs while the car is running, it won't be coped with and would cause serious accidents.
When charging has been completed, disconnect the battery from the CR-2500 after confirming
that the battery has been properly charged. In order to do so, check data such as peak voltage
and charged capacity and whether the battery has become as warm as human body.
Never charge with a current exceeding the nominal capacity (lC) of the rechargeable
battery.
•If a battery is charged with a current exceeding 1C, the battery will overheat and deteriorate.
Plug into a car cigarette
lighter socket.
(or)
Avoid extremely cold and hot places and the direct sunlight when you charge
batteries. It is recommended to perform charging within the 10 ~ 30
°C range.
•Otherwise, it may cause abnormal charging and overheat.

Steady light:
This means that it is ready to display data of
each mode and to start/end each mode.
The RX is in the DISCHARGE mode when
the RX LED lights blue constantly, while it is
in the CYCLE mode when the RX LED lights
red and blue alternatively.
Blinking light:
This means that the CR-2500 charger is in the
battery-check mode or in the charging current
setting mode.
Choose the adequate type of connecter and connect the battery, then the corresponding LED in the ''TX'', ''RX'', and
''GLOW'' LEDs will turn on constantly after blinking as the battery check goes on. The charging current setting screen will
automatically pop up when you connect the battery to RX or GLOW.
When an over-discharged battery was connected, the charger may not be able to detect the battery and the LED lamp
will not light. Wait 2 ~ 3 minutes in the connected state. If the LED lamp lights, charging is possible. If the LED lamp
does not light, charge the battery with the standard charging current (0.1 C).
