Setting %HRR and %Max on Forerunner 405/405CX/410

Depending on whether the Forerunner 405, 405CX and 410 has a resting heart rate (HR) inputted in the user profile, you can display either HR-%HRR¹ or HR-%Max². You can set the %HRR data field when a resting heart rate value is inputted in the user profile. With no resting heart rate, you can set the %Max as a data field.

To make the HR-%Max visible, the resting HR will need to be removed from the user profile. To access the user profile:

1. Press and hold menu on touch bezel.

2. Select Settings.

3. Select User Profile.

4. Enter 000 as resting HR.

The resting heart rate should now read Unknown. You can now change the data field to HR-%Max as a data field on the Forerunner.

¹ Percentage of heart rate reserve.

² Percentage of maximum heart rate.
