TIPS
• The position of the chest belt affects its performance.
Move the chest belt along the strap so that it falls
above your heart.
• Avoid areas with dense chest hair.
• In dry, cold climates, it may take several minutes
for the chest belt to function steadily. This is
normal and should improve with several minutes
of exercise.
NOTE If the belt is kept idle without receiving a heart
rate signal for 5 minutes, the unit will automatically
return to Sleep Mode.
HEADPHONE
You can wear the headphone
as you would for a portable
audio player or similar device.
Connect the headphone directly
to the chest belt as shown.
NOTE For more information on how to connect the
radio (AH310, AH310A, AH310E models only) see FM
Radio section.
