Operating Instructions

The SC-507 is a Multi-Mode Stopwatch featuring single event timing, interval (lap) chronograph, or accumulated (split) chronograph functions. You can time events in any mode up to 24 hours with 1/1000 second resolution. The SC-507's Electro Luminescent (EL) backlight will illuminate the display at any time with the press of a button.

Before operating the SC-507, the display should show all zeros. If the timer is not running (STOP appears), press "B" until all zeros appear.
