How the Watch Counts Calories

∙The watch calculates the number of calories you consume using the elapsed time measured in the Exercise Stopwatch Mode and the age, weight and other data you input in the Basic Data Input Mode. The calorie calculations made by this watch will not be correct unless you input your own personal basic data.

∙The watch also sounds a pacer signal to that you should use as a reference to control the intensity of your workouts. See “About the Pacer Signal” for details.

∙The calorie value on the display is updated every 30 seconds while a stopwatch operation is in progress.

RECALL MODE

turned on for Timers 2, 4, and 5. This loop would be repeated endlessly until you
stop it.
Timer 2	Timer 4	Timer 5
(1 hr.)	(10 min.)	(15 min.)
∙ If Auto-Repeat is turned on for only one timer, that timer’s operation is repeated
until you stop it.
