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.

1.  Start recording exercise. The OwnZone symbol 

 appears on the display. To skip OwnZone determination and use the limits from your  

 

previous session, press OK.

2.  OwnZone determination begins. The process happens in fi ve stages. A beep will signal the end of each stage (if the sound settings are on),
 

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

 determination.
