that was a real response.
there is a wire that sends a signal to the piezo element to make the noise, cut that wire and the timer is a silent timer.
if you aren't familiar with what the piezo element looks like,
take it into radio shack during a slow period and tell them what you need.
if they aren't busy, and are bored, they will open it up and show you the piezo element and cut the wire, then you'll be all set
