Electric motor Idle Up

Mike, this is an extract from the manual:

Transmitter set up:
Check that throttle end point settings are +/-100% .
For Futaba transmitters, reverse the throttle channel.

Normal start up:
Switch the transmitter on and pull the throttle stick down to idle position.
Connect battery pack to the controller
Turn receiver switched “On” (BEC switch on).
You will hear one tone for Brake on or two tones for Brake off, followed by a series of tones that will verify the number of cells connected.
The position of full throttle will be calibrated automatically.:

I'm now confused.
Edit: perhaps the +/- 100% bit is the key element here, but I don't know.

Chris,
Thanks for the link, providing the ESC is still at default then I'm ok with that. I've read that people have had a problem with the ESC being set to soft start but I don't think this is set. I might have a go at factory resetting later.

Alan, your instructions in red are perfect. This is what you should normally do. I was only pointing out that if you did start with the throttle in any other position the motor will not start. The video that Chris linked shows that if you leave the throttle stick fully open for a few seconds you will enter programming mode. And although they removed the prop for safety you will have seen that the motor did not spin.
Phil's description of always connecting the battery with the throttle fully open so that it knows where full throttle is is a very unusual and antiquated way of doing things.
And to be clear, I always connect the battery with my throttle off and/or arming switch off. But I know that if I get it wrong my ESC will not work until it sees an off command.
