"If you love it simple" is their tag-line, but I don't really see anything simple about having to reference a piece of paper and then dial a 13 digit number each time I want to call home.
"You can allocate 10 speed dial numbers, each under one of the ten digits. You can allocate a telephone number (in this case, 0612345678) to a speed-dial number (in this case 1) by entering: * * 1 * 0612345678#. Subsequently, hold down the ‘1’ button for two seconds to automatically call the telephone number entered. To delete the speed-dial number in the above example, enter * * 1 * #. If you wish to alter a telephone number allocated to a speed-dial number, simply write over it with the new number."
