Changed line 15 from:
## The Throttle switch is opened, i.e. pin D11 is HIGH: close the switch.
to:
## The Throttle Cut switch is opened, i.e. pin D11 is HIGH: close the switch.

Added lines 8-18:

If the throttle channel (channel 3 by default) is not working:

*Check why this channel is not responding by issuing a PRINT PPM command:\\
you should see that CH3's pulse = the lowest possible value (this value is set by var PWL3, display it with PRINT PWL3)
*then check that CH3's pulse is constant even if you move the throttle pot.
*There are 2 possible causes:
## The Throttle switch is opened, i.e. pin D11 is HIGH: close the switch.
## The throttle channel is forced to the lowest possible value by the security check, possibly because the throttle pot is not well calibrated.\\
do PRINT POT3, PRINT KL3, PRINT TSC and check that POT3-KL3 < TSC else redo calibration for POT3.

Changed line 3 from:
The software checks the position of the throttle potentiometer at startup when you turn on your transmitter, and each time you exit the Command mode. If the stick is not in the idle position, it will be disabled until you move it back to this idle position.

Changed line 5 from:
The threshold value corresponding to the idle position is defined by the Global variable TSC (see [[Cmd.GlobalVars|Global variables]]). TSC values range is [0-1023] and the default is 50, roughly 5% of 1024. If your throttle channel is permanently cut the first time you use the software, then your throttle potentiometer is not properly calibrated and you must perform the [[Calibration|potentiometer calibration]]. Notice that the throttle potentiometer number is defined for each model by the global variables THR1...THR9 (see [[Cmd.GlobalVars|Global variables]]), its default value is 3.

If the throttle channel is connected to an ESC, then you must also calibrate this ESC. Calibration lets it know what zero and full throttle are with your transmitter. Refer to the manual of your ESC to learn how to do it.

the TSC variable, you must perform the throttle [[Calibration|potentiometer calibration]]. The throttle potentiometer number is defined by the global variable THR (see "Understanding global variables" in  [[Command|Command mode]] page), its default value is 3.

After calibrating POT3, enter Command Mode. If the potentiometer has a mechanical trim, move the trim slider to its middle position, then move the potentiometer to its lowest position and type ? POT3:
->1>? POT3\\
POT3=87\\

Here, 87 is the lowest value returned by POT3. Since the default value for TSC is 50, the software will disable the throttle at startup.

Now let's change the TSC variable:

TSC=96\\

Here we used 96 instead of 87 to define a 10% idle threshold: 87 x 1.10 = 95.7
