I just bought a Sportline 241 last week. The instructions are as follows. Note that there are no instructions for setting the 12/24 hour time option. Mine is in 24 hour mode (which is what I wanted), but I do not recall if it arrived that way or if I stumbled onto this mode when setting the time/date or alarm functions.

I hope this helps.
