OWNZONE
Polar Heart Rate Monitor is able to determine the
individual training heart rate zone for you. This exercise
zone is called your OwnZone (OZ).
For most adults, OwnZone corresponds to 65-85 % of the
maximum heart rate. OwnZone is suitable for
cardiovascular training either for health-related or fitness
improvement purposes.
OwnZone works well for those whose goal is weight
control via physical activity and exercise, because the
OwnZone corresponds to intensity from “light to
moderate” to “moderate”. Exercise of this intensity level
can be conducted even for extended periods safely and
often yields the best results for weight loss.
The OwnZone can be found during a warmup period of an
exercise session lasting 1-10 minutes.

OwnZone is easily determined by walking and jogging as
instructed below. However, you are able to find your
OwnZone with other exercise modes as well, e.g. exercising
with a stationary bike. The principle is that you start
exercising very slowly with light intensity and gradually
increase your heart rate.
1. Check that you have set your personal user information
correctly.
2. Because OwnZone determination needs every heart beat
to be picked up properly, make sure that the transmitter
belt is tight enough and the electrodes well moistened.
