Hi Rashers
I think you need to tick the 'Squawk' box with '7700' set-up in it. Make sure you untick the other boxes. Then tick the send email box and put your email address into the space provided.
Unfortunately it means you cannot set-up other alerts as they will all go to you in box.
I have not used it for a while and when i did i had to many alerts setup my inbox was un-managable. Providing you only set the one alert you should not have a problem.
