Charging method
Avoid charging where the charger will be exposed to direct sunlight.
Perform charging within the 5~40｡C range.
•Normal charging will become impossible and will cause abnormal heating.

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, try
charging with a charger of the standard charging current (0.1C).
Check the charging current at the current setting screen. To change the charging current, turn
the SELECT dial while this screen is being displayed. When the CURRENT button is pressed,
the current setting screen can be recalled even if it is closed.
(Charging current setting range)
TX: 0.5A~2.0A (0.1A steps)
RX: 0.05A~2.0A (0.05A steps)
GLOW: 1.00A~2.5A (0.5A steps)
Never charge with a current exceeding the nominal capacity (1C) of the
charged battery.
•Charging with a current exceeding 1C will cause the battery to abnormally heat up
and deteriorate.
The current setting screen closes and the data display screen opens. Each data is displayed
during charging.

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.
(Displayed for about 5 secs)
[Data display screen]
Each data other than the output voltage is displayed
until the next battery is connected even if charging
is finished and the battery is disconnected.
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.
(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.

(Data display and charging operation output switching)
Normally, when a battery is connected, its output data is automatically displayed and the
charging operation by button becomes possible. However, when connecting batteries to the
two outputs simultaneously, you may want to switch the output that is operated. In this case,
switch the output by pressing the SELECT button. Each time the SELECT button is pressed,
the output is switched in TX->RX->GLOW->TX--- order.
Switch the output to
be operated by pressing
the SELECT button.

When charging 2 outputs simultaneously, part of the LED of the "Charging Method" item at
the left may be different. Perform charging by referring to the display example shown below.
[Connection example]
When a receiver battery was connected while charging a transmitter battery, the LEDs are
displayed as shown below and the charger enters the receiver battery side charging current
setting mode.

side state.)
When a charging current setting mode was finished, the LEDs are displayed as shown below
and the receiver battery side data display and charging start and end operations are possible.

When the screen display mode was switched to the "TX" side by pressing the SELECT button
twice, the LEDs are displayed as shown below and the transmitter battery side data display
and charging start and end operations are possible.

Error display, etc.
[When battery disconnected while charging]
When the battery is disconnected while charging, an audible
alarm sounds and the error message shown at the right
appears. The "CHG" LED goes off.
[When input voltage dropped]
When the input voltage dropped, the error message shown at
the right appears. Check the parent power supply.
[When output side shorted]
When the output side of the charger is shorted, the error
message shown at the right appears. Remove the short
circuit.
[When output voltage rose abnormally]
When the output voltage of the charger rose abnormally,
charging is forcibly ended and the error message shown at
the right is displayed. Check the battery.
<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.
<Recycling nickel batteries>
Used nickel batteries are a valuable resource. Tape or other wise process the
terminals so that are not shorted and take the used battery to your local recycling
center.
