Power Source Precautions
Select the power source of large output capacity.
It is recommended to use 12V car batteries with no less than 40Ah or DC power supplies with no less than 15A
at 12 to 16Vdc that have current overload protection circuit (fuse). If you use a power source whose current
output capacity is less than the charging current, you may damage the power source.(The guaranteed operating
range of CDR-5000 is from 11V to 16V.)
Don't use the car battery installed in a car. Prepare a 12V standalone car battery for
charging.
If you use the battery installed in your car, the battery could dry up and become impossible to start your car
engine.And please don't connect CDR-5000 to your car battery while the engine is running in order to avoid the
dry-up of the car battery, because it may cause not only environmental problem and space securing problem, but
also malfunctions of CDR-5000 due to fluctuation of input voltage and vibrations.
Never use 24V batteries.
Never use 24V batteries commonly used in trucks, otherwise CDR-5000 would be damaged.
Thank you very much for purchasing a rapid charging & discharging equipment CDR-5000.

Safety Precautions
Never use CDR-5000 in the near range of flammable materials.
*Electric sparks generated by connecting or disconnecting batteries are very dangerous to trigger a fire.
Do not operate CDR-5000 for charging or discharging with wet hands.
*It may expose you to suffer electric shock especially when the voltage for charging or discharging is very
high.
Never charge or discharge any batteries other than NiCd and NiMH batteries.
*Charging or discharging the batteries other than NiCd and NiMH batteries may cause abnormally high heat
generation and fire.
Never connect batteries in the wrong direction.
*Wrong connection may cause the improper work of protection circuit and the excessive heat generation,
and may damage the CDR-5000 internal parts.
Never do an additional charging or discharging after the charging or discharging.
*It is very dangerous to do so because the "Auto-cut" will become unable to function, and the batteries will be
over-charged and overheated. Also, over-discharge may damage the batteries.
Never let the CDR-5000 be wetted by water.And do not use CDR-5000 at places such
as extremely high humidity, rain and snow.
*CDR-5000 contains electronic parts that are susceptible to malfunction by intrusion of water such as rain.If
your CDR-5000 were wetted by water, it is strongly recommended to return it for repair.
Do not use or store CDR-5000 at heavily dusty places.
* Dust, if it enters in CDR-5000, may cause malfunctions or failures since CDR-5000 has a precision elec-
tronic circuit inside.
Do not start charging or discharging while the batteries are still warm.
*If batteries are charged while they are warm, the batteries cannot be charged up to their full capacity and
cannot draw their maximum performance.There is also a possibility of abnormally being heated.So be sure
not to start charging or discharging before the batteries are cooled down.

generation.
The "Delta-peak" detection may not work properly when charging such batteries that
are newly acquired or left unused for a long time. Please stop charging when the tem-
perature of the batteries rises abnormally.
*NiCd and NiMH batteries that are newly acquired or left unused for a long time are unlikely to be detected
by "Delta-Peak" that shows a sign of completion of charging.If you continue charging the batteries as they
are, the batteries will be abnormally heated and cause danger.
Be careful so that you won't short electric cords by pinching them.
*A short between electric cords may cause high heat generation or fire to the batteries.
Monitor frequently the level of charging and discharging by data and/or chart shown on
the display while doing it. If the level of charging and discharging is unusually high,
stop it immediately.
*"Auto-cut" may not work correctly due to unknown reasons.

Caution:The setting should be carried out taking into consideration the types of batter-
ies and the number of battery cells. Parameters used in this description are rough
targets that are mainly intended to avoid damages to batteries.These targets are not
necessarily optimal to the batteries that are used for competitions.
The term of "1C" in this manual is defined by the charging/discharging capacity of a
battery cell.For example, when "2400mAh" is shown on a battery cell, then "1C" for the
battery is 2.4A.When "3300mAh" is shown on a battery cell, then "1C" for the battery
is 3.3A.
[DX SET-UP]
It is possible to memorize 10 types of charging/discharging data for DX. For example, if you memorize
two types such as 4 NiMH cells with 3300mAh and 6 NiMH cells with 3300mAh, you can select one
out of two types by selecting memory number.
<Operation key>
Push " " or " " key to select the memory number.
SET CHARGE
This is to set the charging current for DX. 0.1-12A (0.01A step)
However, the maximum charging current varies according to the charging voltage. (See page 27)
* If the "WARNING" is set to "ON" on the INITIAL-SETTING", the confirmation message "CHARGE AMPERE IS TOO
HIGH!" will be shown on the screen when the current is set between 5A and 12A. If there is no error, continue setting. The
message will be shown no more than twice. Please be aware that charging at a high current may damage batteries.
* It is recommended to set the charging current somewhere between 1C and 1.5C. Here 1C is the typical capacity specified by its
manufacture. In case of charging a large number of cells, it is recommended to set the charge current within the maximum
current shown in page 27.
(Example) When charging a NiCd battery of 2400mAh typical, the target charging current will be derived from the following
calculation: 2400mAh x 1.0=2.4A, 2400mAh x 1.5=3.6A
Therefore set the charging current in this case between 2.4A and 3.6A. However, in case of NiMH batteries, it is recommended
to charge at 4.0A for 3000mAh battery and 4.5A for 3300mAH battery.
When charging a large number of battery cells at a time, CDR-5000 might automatically limit the charging current or stop
charging before detecting correct delta-peak by its current overload protection circuit. Please set appropriate parameters within
the range listed in page 27 by estimating the maximum voltage and charging current.
SET DISCHARGE
This is to set the discharging current for DX. 0.1-40A (0.01A step)
However, the maximum discharging current varies according to the discharging voltage. (See page 27)
*If the "WARNING" is set to "ON" on the INITIAL-SETTING", the confirmation message "DISCHARGE AMPERE IS TOO
HIGH!" will be shown on the screen when the current is set between 10A and 40A. If there is no error, continue setting. The
message will be shown no more than twice. Please be aware that discharging at a high current may damage batteries. It is
strongly recommended to cool the battery by cooling fans when discharging over 10A.
*It is recommended to set the discharging current somewhere between 1C and 4C. Here 1C is the typical capacity specified by its
manufacture.
(Example)When discharging a battery of 3000mAh typical, the target charging current will be derived from the following
calculation: 3000mAh x 1.0=3.0A, 3000mAh x 1.5=12.0A
Therefore set the discharging current in this case between 3.0A and 12.0A.

*Be sure that you don't charge a battery over its typical current (1C) specified by its manufacture.
(Example) When charging a battery of 1000mAh typical, the target charging current should be lower than 1A (1000mAh x
1.0=1.0A).
*Charging a battery at over 1C may cause abnormal heat generation or deterioration of the battery. Never charge a battery at over
1C especially when the battery is connected to a transmitter.
SET DISCHARGE
This is to set the discharging current at TX/RX. The setting range is from 0.1 to 5A. (0.01A step)
However, the maximum discharging current varies according to the discharging voltage. (See page 27)
*It is recommended that discharging current is in the range between 1C and 2C. Here 1C is the typical capacity specified by its
manufacture.
(Example) When discharging a battery of 1000mAh typical, the target discharging current should be between 1.0A and 2.0A
(1000mAh x 1.0=1.0A, 1000mAH x 2.0=2.0A).
*Discharging a battery at very high current may cause abnormal heat generation or deterioration of the battery. Before discharg-
ing the battery of a transmitter, be sure to disconnect the battery from the transmitter. The CDR 5000 is not applicable for
discharging those batteries with protection circuit. (Examples: NT-8A, NT8S1100 for T9Z and so on.)
CYCLE MODE
This is to set the number of cycle times of charging/discharging at TX/RX. 1 TIME means one cycle of
a charging and a discharging. The setting range is from 1 through 99.

2. Connecting Battery
Caution:Never charge or discharge any batteries other than NiCd and NiMH batteries.
Charging or discharging the batteries other than NiCd and NiMH batteries may cause
abnormally high heat generation and fire.
Preparation: After selection of memory numbers, settings of all parameters and final
confirmation on the SET-UP screen push "Data" key to get DX-DATA screen. Pushing
"Data" key from DX DATA screen can accessTX&RX DATA screen.
1)Set DX DATA number or TX&RX DATA number to "01"
by using " " and " " keys.
*Make the Thermo Sensor contact to the battery when charging at DX
terminal. If you have Thermo Stand (option), lay the battery on the Thermo
Stand (not applicable for batteries with 7cells and more and straight packs)
instead of using Thermo Sensor. Thermo Sensor and Thermo Stand are not
applicable to batteries at TX/RX.
2)Connect a battery to the output port that should be well
matched to the battery type.Make sure that the polarity is
correct.
Caution: In case of discharging a battery of a
transmitter, do not try to discharge the battery
while it is connected to the transmitter. A pro-
tection circuit in a transmitter will prevent it.The
CDR 5000 is not applicable for discharging those
batteries with protection circuit. (Examples: NT-
8A, NT8S1100 for T9Z and so on.)
*DX port: This port is for the batteries for motors that require rapid charging
and discharging.
*TX/RX port: This port is for batteries for transmitters and receivers.
*DX and TX/RX ports of CDR-5000 can be used simultaneously
3)MODE indication changes from "NO BAT." to "READY".
*If "SHORT" is displayed in MODE, please check the possibility of reversal connection of a battery, electrical short and over-
discharge. If the "WARNING" is set to "ON" on the INITIAL-SETTING", the warning message "SHORT OR REVERCE!" will
be shown on the screen.
4)Use Terminal Harness for obtaining the each cell data of a battery connected to DX terminal.
Be sure to connect DX terminal first before connecting Terminal Harness.
*In case of using Terminal Harness, it is necessary to input the exact number of cells in the "CELL NUMBER" on the SET-UP
screen.

3. Start of Charging/Discharging
[Charging at DX]
1)Push "DX CHG" key.
2)The red LED of "DX Charging" turns on. MODE indicator changes from "READY" to "CHG".
And charging will start.
[Discharging at DX]
1)Push "DX D-CHG" key.
2)The blue LED of "DX Discharge" turns on. MODE indicator changes from "READY" to "D-
CHG". And discharging will start.
*It is strongly recommended to cool the battery by cooling fans when discharging over 10A.
[Charging at TX/RX]
1)Push "TX/RX CHG" key.
2)The red LED of "TX&RX Charging" turns on.MODE indicator changes from "READY" to "CHG".
And charging will start.
[Discharging at TX/RX]
1)Push "TX/RX D-CHG" key.
2)The blue LED of "TX/RX Discharge" turns on. MODE indicator changes from "READY" to "D-
CHG". And discharging will start.
Caution for discharging:Sensing the voltage of the battery while discharging atTX&RX,
CDR-5000 automatically calculates the voltage level that stops discharging. It sug-
gests that if you discharge a battery that has been already discharged or a battery
whose voltage is already very low, the battery will be over-discharged. Never do an
additional discharging
If the voltage of a battery under discharging declines in the early stage and becomes
lower than 0.8V/cell, stop discharging.
It is recommended to use a cooling fan to keep the temperature of a battery low while
discharging in Cycle Mode, because the temperature of the battery under Cycle Mode
generate a large amount of heat due to continuous operation. And it is also recom-
mended that "CYCLE DELAY" in the "INITIAL SETTING" be set "ON" during the us-
age.
