• 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.
