Interval Timer Mode
Interval Timer Mode offers a flexible six-interval countdown timer,
and can retain settings for up to five different training sessions. It
includes warm up and cool down intervals and four training
intervals for each training session. You can set the group of four
training intervals to repeat up to 99 times. You can set the warm-
up interval to run one time at the beginning of your training
session and the cool down interval to run one time at the end of
your training session.

Chronograph Mode example

Recently you heard that a training method for long distance
runners called the run/walk method can help you increase your
overall endurance and burn more calories. This method calls for
running for a period of time followed by a short period of walking.
You decide to use Chronograph Mode to help you try this method.
You press START/SPLITto begin your run and then after 10
minutes of running you press START/SPLITagain and walk for 2
minutes. You continue using these two timing sequences until you
have completed a 60 minute run/walk.
