Brake MAX 
point setting
* Since the data is read at the end of setting of all points, the points cannot be set independently.
* If the amp power was turned off during setting, the setting points cannot be memorized. (The previous settings are retained.)
* The confirmation beep sounds only when the motor was connected.
If the LED does not go off 
but blinks rapidly, setting 
was not performed 
normally. Repeat setting 
from "Neutral point 
setting".
Set the steering angle adjustment function (ATV) to 
100% and the ABS function and acceleration function 
to OFF using the transmitter throttle channel function.
If the steering angle is too large or the ABS and acceleration 
functions are on, erroneous operation may occur.
*When using the ABS function, after setting up 
the MC230CR / MC330CR, stop the reverse 
function, then turn on the ABS function. If the 
ABS function is on, the MC231CR / MC331CR 
cannot be set up correctly.
