Garmin 405cx Guida Utente

Getting Started

While you are trying to pair your 

heart rate monitor with your 

Forerunner for the first time, move 

10 m away from other heart rate 

monitors. 
The heart rate monitor is on standby 

and ready to send data. Wear the 

heart rate monitor directly on your 

skin, just below your breastplate. 

It should be snug enough to stay in 

place during your run.

1.  Push one tab on the strap through 

the slot in the heart rate monitor. 

Press the tab down.

2.  Wet both electrodes on the back 

of the heart rate monitor to create 

a strong connection between your 

chest and the transmitter.

3.  Wrap the strap around your chest 

and attach it to the other side of 

the heart rate monitor.

  note: The Garmin logo should 

be right-side up.
