FEATURE EXPLANATIONS:
1. Brake settings: Brake Enable/ Brake Disable, default is Brake Enabled

    -> When NOT using balance discharge protection function(i.e. DO NOT plug the balance charge connector into the balance discharge protection socket on ESC, in this case, the ESC only monitors the voltage of whole battery pack)

              1) For Li-xx battery, number of battery cells are judged automatically, low/medium/high cutoff voltage for each cell are:2.5V/2.75V/3.0V. For example:3 cells Li-Poly, when medium cutoff voltageis set,the cutoff voltage is 2.75*1.44=8.25V.

              2) For Ni-xx battery,low/medium/high cutoff voltages are 60%/65%/70% of the startup voltage (i.e. the initial voltage of battery pack). For example: 6 cells NiMH battery,fully charge voltage is 1.44*6=8.64V, when "Low" cutoff voltage is set,the cutoff voltage is 8.64*60%=5.2V.                            

    -> When using balance discharge protection function (i.e. Plug the balance charge connector into the balance discharge protection socket on ESC,in this case,the ESC monitors the voltage of whole battery pack AND the voltage of each cell)For Li-xx battery,low/medium/high cut off voltage for each cell are 2.5V/2.75V/3.0V.when the voltage of any cell in battery pack is lower than the cutoff threhold,the protecting program is activated.

5. Startup Mode: Normal/Soft/Super-Soft,default is Mormal startup. Normal is good for fixed-wing aircraft.Soft/Super-Soft are good for helicopters,the initial speeds of soft/super soft mode are pretty slow,1 sec(soft startup)/2sec(super-soft statrup) from startup to full speed.Butif throttle is clsed(throttle stick moves to bottom)and opened again(throttle stick move up)within 3 seconds after the first startup,the startup will be normal mode to get rid of the chances of crash caused by slow throttle respones in aerobatic fly.

6. Timing: Low/Medium/High,default is Low. In normal cases,low timing can be used for most motors.But for high efficiency,we recommend the Low timing for 2 poles motor and Medium timing for 6 poles and above.For higher speed,High timing could be chose.        ATTENTION: After you changing the timing setting,please test your model on the ground first!

Begin To Use Your New ESC:
Before using your new ESC,please check all the connections to make sure that they are reliable,then startup the ESC in the following sequence:

1. Move the trottle stick  to bottom,and then switch on the transmitter.
2. Connect battery pack to ESC,the ESC begins the self-test process ,after 2 seconds a long "beep----" tone should be emitted, which means self-test is OK,and then the motor begins to play music,now the aircrft /helicopter is redy to go flying
     ->If nothing is happened,please check the battery pack and all the connections; 
     ->If a special tone "56712" is emitted after 2 Beep tone (beep-beep),means the ESC has entered the programming made,i.e. the throttle channl of your transitter is reversed,please set it correctly;
      ->If a very rapid "beep-beep-,beep-beep-"tone is emitted,mean the input voltage is too low or too high,please check your battery
3. After the motor begins to play music,several groups of "beep-" tones should be emitted,presenting the setting value of each program item.You can move throttle stick upwards to go flying at this time.In the unnecessary to wait the "beep-"tone finished.
4. "VERY IMPORTANT!" Because different transitter has different throttle range,we strongly suggest you using the "Throttle Range Setting Function" to calibrate throttle range.

2. Throttle signal abnormal alert tone : When the ESC can't detect the normal throttle signal,such an alert tone will be emitted:"beep-,beep-,beep-,"( every"beep-" has a time interval about 2 seconds.)
3.Throttle stick not in bottom alert tone: When the throttle stick is not bottom(lowest) position,a alert rapid alert tone will be emitted:"beep-,beep-,beep-,"(every"beep-"has a time interval about 0.25 second.)

2. Over-heat protection: When the temporature of ESC is over 110C, the ESC will reduse the output power.
