Question by: Product code: 49-6322

Q. We have a timer like this, how do you set the length of time the alarm sounds for? We had it set for 3 seconds, it used to work great but this function seems to have stopped working, we now have to manually switch off and reset.

A. Hi George, thank you for your question. The instructions can be found here.
