Forerunner 405 Owner’s Manual

Using Accessories

Synthetic fabrics that rub or flap 

against the heart rate monitor 

can create static electricity that 

interferes with heart rate signals. 
Move away from sources of 

strong electromagnetic fields and 

some 2.4 GHz wireless sensors, 

which can interfere with your 

heart rate monitor. Sources of 

interference may include very 

high voltage power lines, electric 

motors, microwave ovens, 

2.4 GHz cordless phones, and 

wireless LAN access points. 

Heart Rate Zones

 

Caution: 

Consult your 

physician to specify heart 

rate zones/targets that are 

appropriate for your fitness 

level and health condition. 

Many athletes are using heart rate 

zones to measure and increase their 

cardiovascular strength and improve 

their level of fitness. A heart rate 

zone is a set range of heartbeats per 

minute. The five commonly accepted 

heart rate zones are numbered from 

1–5 according to increasing intensity. 

The Forerunner sets the heart rate 

zone ranges (see the table on 

page 

45

) based on your maximum and 

resting heart rates set in your user 

profile (see

 page 29

).

You can also customize your heart 

rate zones in your user profile of 

Garmin Connect or Garmin Training 

Center. After customizing your heart 

rate zones, transfer data to your 

Forerunner.
