Mc231Cr/Mc331Cr - FUTABA 2HR Instruction Manual

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)
(Pushbutton switch operation)

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.
Overcurrent
protection
Heat protector
Low voltage
operation
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.
Operation
Amp power ON
High point
Neutral point
Brake MAX point
(Amp power left on alarm)
When the transmitter power
was turned off first.
* Confirmation beep only sounds when the motor was connected.
MC231CR/MC331CR Function

MC231CR/MC331CR

(Power switch)
ON
set the power switch to ON.
When an overcurrent flows due to an output short circuit, etc., the overcurrent protection circuit automatically
limits the current to protect the FET.
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.
When the NiCd/NiMH battery voltage drops, this function limits the motor output current and ensures steering
operation.
After the speed drops, immediately recover the vehicle.

* When desired, you can enable the cancelled reverse
function by repeating the operation shown at the left.
(The reverse function is switched alternately.)

*Becomes brighter nearer the high
point.
*Becomes brighter nearer the
brake MAX point.
*Not used with PCM receivers.
*When the transmitter is OFF, this function is
not performed in environments such that the
