BRAKE/REVERSE OPERATING INSTRUCTIONS

Operation can be switched to reverse operation by returning the throttle trigger (or throttle stick) from the brake

position to the neutral position.

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)

While pressing

the pushbutton switch,

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.)

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.

PROTECTION CIRCUIT OPERATION

The following protection circuits are built into the MC230CR / MC330CR. When a protection circuit operates,

remove the cause before operating the model again.

*Not used with PCM receivers.

*When the transmitter is OFF, this function is

not performed in environments such that the

servo operates erroneously.

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.

Overcurrent

protection

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 Ni-Cd/Ni-MH battery voltage drops, this function limits the motor output current and ensures steering

operation.

After the speed drops, immediately recover the vehicle.
