It seems really good, no false alarms or anything like that!
here is the owners manual if you don't have one -
http://www.clifford.com/guides/ogs/concept50uk_owners.pdfThe problem i have is that i don't have a cherp sound, there is an option to disable this, but when i try and turn it back on it does not seem to work!
If you your vallet code (you should) this is what you do:
enter vallet code (e.g 1-2-3) -
Flip latch down once
flip it up and back to center
Flip latch down twice
flip it up and back to center
Flip latch down three times
flip it up
(you are now in your vallet mode/ alarm disabled)
imediaetly hold down the switch for 3 secs and release and you should be in feature select mode.
hit the switch 5 times down and this should turn the cherps on or off!
does it work for you?
