This method works for most ESCs but not all. As mentioned in the manual, we really recommend you do the manual calibration instead, which always works. 

But if you do decide to try this anyway, the cable should be connected and the CLI switch should be in flight mode. Be prepared to pull the power if a motor starts shuddering. Remember, the props should be OFF to avoid any danger of injury.

Thanx Chris. I bought the copter assembled so the wires ( I assume the dark blues ones) are not free.

I am not sure what to do

You're supposed to use the signal wires, not the power ones!

We all have a Homer Simpson inside...

So I disconnect the other three and leave one connected. And do 

• 
  With NO BATTERY CONNECTED, plug the three-wire plug of the ESC you want to calibrate into channel 3 of your RC receiver.
• Turn on your transmitter and push the throttle position to full up.
• Plug a LiPo battery into the ESC
• You will hear a series of beeps. Now drop the throttle to full down. You will hear a different series of beeps. You may now disconnect your LiPo. Your ESC is calibrated.

QUESTION IS CLI switch is away from RC pins? And 4-wire power cable that goes to RC pins should that be on or off?

"So I disconnect the other three and leave one connected."

No. I just just showed you that diagram to indicate which were the signal wires, as opposed to power wires. 

As stated in the very manual text you quoted: "plug the three-wire plug of the ESC you want to calibrate into channel 3 of your RC receiver." Just do that, exactly as written.

You leave the other three connected to your PDB. Once you've done one, plug it back in and move to the next. Repeat for all four.

The ESCs are 3D robotics

This method works great for me. It should work 100 % of the time with HK style programmable ESCs. 

You should have everything hooked up as in normal flight. 

Flight mode does not matter.

Special gratitude for Chris, Mr. Sanchez and Mr. Short

I get my green LED blinking, so I am looking in the trouble shooting manual. 

I calibrated the ESCs as was told and nothing burnt :)

I repeat the steps one more time tonight

Thank you again from both Homer and myself

Ok it worked, However I had to push the THROTTLE stick all the way down and to the LEFT. 

So my MODE I or II are confsued

I am in Canada so it should have been MODE2 but I am MODE1 !!!!

That means that your yaw channel is reversed.
