Set time and date on a sportline 240 - Sportline 345 Electronic Pedometer

Do you mean the 240 Econosport sports watch (stop watch)? The manual is available for download here: http://www.sportline.com/product.php?prod=26

To set the date and time, press the center button (Mode) on the top three times. Press the left button (Split/Reset) to select seconds, minutes, hour, day, month or date. Use the right button (Start/Stop) to change the value of each selection. Hold the Start/Stop button to change the value rapidly. (When changing the seconds, you will only be able to set the value to 00.)

Press the Mode button to return to the Time Display.

I hope this helps.
