STOPWATCH EASY TO USE
Whether your timing the length of a presentation, or how long it took you to run that two kilometer race, you might try the 95LX's Stopwatch function -- it's really pretty easy to use.
From the APPT main screen press (F9) (Watch) and (F4) (Reset) to clear the clock. Press (F6) to start the timer and (F6) again to stop it. You will see the time elapsed displayed to the 100th of a second.
You could also use Stopwatch to time phone conversations, sales presentation, or anything that you can rehearse and that needs to fit into a specified time slot.
