I have just moved into a house with a ts400 alarm system and I would like to change the pass code. But no matter what I do it just won't happen.
In fact I can't even get passed the first step in the manual!
It says to put in the first 3 digits of the code then press home then 4 but as soon as I press home the alarm starts to set.
What am I doing wrong.
