Turn on the Bluetooth on your mobile device.

Put on your arm or chest monitor (if you're using an arm monitor, you have to push the on/off button to turn it on; if you're using a chest monitor, it will turn on automatically).

Log into your RookMotion app.

Tap "Training" in the lower menu and choose any kind of training.

Tap the red button with a heart rate monitor icon.

In the next screen, tap the red button "Add monitor".

Your monitor should appear on the list. Tap on it and it will pair to your app.

Once you completed these steps, you should be able to see your Rook monitor and the text "Connected" in green letters.
