The calculation used for the heart rate target zone is:
(220 minus your age) multiplied by a percent.
For example:
Low range: (220 minus your age) multiplied by 55%
High range: (220 minus your age) multiplied by 85%
Refer to Table 1 in Using SmartRate.

•
To use the touch-sensitive grips on the EFX, grasp both
grips and wait five to ten seconds. Make sure both hands
are moist.
•
If Hr appears in the HEART RATE display, the EFX is not
detecting a signal, or has not yet determined your heart
rate.
Note: When a signal is detected, the heart rate icon
flashes and a number appears in the HEART RATE
display that indicates your heart rate.
•
Always face forward on the EFX and use the stationary
handrail for balance. Keep upper body movement to a
minimum.
