Determining Your OwnZone Heart Rate Limits
Find your OwnZone limits in 1-5 minutes during a warm up period by cycling or walking/jogging. You should start exercising gently at a light
intensity and gradually increase intensity to raise heart rate.
Before you start, make sure that,
• Your user settings are correct.
• The OwnZone function is activated. The cycling computer will automatically determine OwnZone every time you start exercising if the
OwnZone function is on.

and the display will automatically light up (if you have switched the backlight on once before). Avoid stopping during OwnZone
determination.
