Operation Precautions
 WARNING
using a NiCd/NiMH battery to power your system, always charge and check
￸ When
the battery voltage prior to operation. Should the battery discharge below the
minimum voltage level, control will be lost.
Prior to operation always perform a range test. Even one abnormality in the R/C
￸ system
may cause loss of control.

Storage and Disposal Safety Precautions
 WARNING
the end of a day's operation, store the system with NiCd/NiMH battery
￸ Atdischarged.
Be sure to recharge the system before it is used again.
You should fully discharge your system's batteries periodically to prevent a condition
called "memory". For example, if you only make two runs in a day or you regularly use
a small amount of battery's capacity, the memory effect can reduce the actual capacity even if the battery is charged for the recommended amount of time.
not throw a NiCd/NiMH battery into a fire. Do not disassemble or attempt to
 Do
repair a NiCd/NiMH battery pack.
Overheating, damage and acid leakage may lead to burns, loss of eye sight as well as
numerous other types of injuries. The electrolyte in NiCd/NiMH batteries is a strong
alkali. Should you get even the smallest amount of the electrolyte in your eyes, Do
Not rub. Wash immediately with water, and seek medical attention at once. The electrolyte can cause blindness. If electrolyte comes in contact with your skin or clothes,
wash with water immediately.
not leave the radio system or models within the reach of small children.
 Do
A small child may accidentally operate the system. This could cause a dangerous
situation and injuries. NiCd/NiMH batteries can be very dangerous when mishandled
and cause chemical damage.
6
 CAUTION
not store your R/C system where it will be exposed to the following conditions.
 Do
• Extreme heat or coldness
• Exposed to direct sunlight
• Where humidity is high
• Where vibration is prevalent
• Where dust is prevalent
• Where there is steam and condensation
Storing your R/C system under adverse conditions could cause deformation and
numerous other problems with operation.

and store in a cool, dry place.
If the batteries are left in the model, electrolyte may leak and damage the model.

MC231CR Operation
Forward :
Brake :
Throttle stick is turned
up, the speed increases.
Throttle stick is turned
down, the brake works.
Reverse :
Operation can be switched
to reverse operation by
returning the throttle stick
from the brake position to
the neutral position. Then
turn down the stick.
Stick is turned
down from the

MC231CR Function
CANCELLING THE REVERSE FUNCTION
The amp reverse function can be cancelled by the following method so that the model can be used even in races
that prohibit reverse running. (Brake operation only)

function
cancellation
While pressing
the pushbutton switch,
ON
set the power switch to ON.
* When desired, you can enable the cancelled reverse
function by repeating the operation shown at the left.
(The reverse function is switched alternately.)
BRAKE/REVERSE OPERATING INSTRUCTIONS
Operation can be switched to reverse operation by returning the throttle stick from the brake position to the neutral
position.
PROTECTION CIRCUIT OPERATION
The following protection circuits are built into the MC231CR. When a protection circuit operates, remove the
cause before operating the model again.
When an overcurrent flows due to an output short circuit, etc., the overcurrent protection circuit automatically
limits the current to protect the FET.
Overcurrent
protection
Remove the cause of the short circuit, etc. before operating the model again.
When abnormal heating of the FET due to an overload, etc. is detected, the heat protector operates so that
the speed is gradually reduced.
When the FET temperature drops, the heat protector automatically resets. However, remove the cause
of the overheating before operating the model again.
Heat protector
When the NiCd/NiMH battery voltage drops, this function limits the motor output current and ensures steering
operation.
Low voltage
operation
After the speed drops, immediately recover the vehicle.
CHECKER LED DISPLAY
The amp operates linearly in proportion to the amount of forward, reverse, and brake operation. The amp operating
state can be checked with the checker LED as shown below.
