•Always face forward on the EFX and use the stationary
handrail for balance. Keep upper body movement to a
minimum.
Wearing a Chest Strap
During a workout, the heart rate features appear on the
display when you wear a chest strap. To receive an accurate
reading, the chest strap needs to be in direct contact with
your skin.
1. Carefully dampen the back of the strap with tap water
Refer to Diagram 8.
Note: Do not use deionized water. It does not have the
proper minerals and salts to conduct electrical impulses.
2. Adjust the strap and fasten it around your chest. The strap
should feel snug, not restrictive. Refer to Diagram 9.
Diagram 9: Adjust chest strap
3. Make sure that the chest strap is right side up, lies
horizontally across your chest, and is centered in the
middle of your chest. Refer to Diagram 10.
Diagram 8: Moisten chest strap
Diagram 10: Fasten chest strap
After you put on the chest strap, face the display console for
a few seconds. This allows the receiver in the console to
recognize the signal from the chest strap.
Owner’s Manual: Heart Rate Features15
Using the Heart Rate
Touch-sensitive
handrail grips
Touch-Sensitive Handrail Grips
While exercising, you must grasp both touch-sensitive
handrail grips for a minimum of five to ten seconds to
transmit your heart rate to the display. Refer to Diagram 11.
Diagram 11: Touch-sensitive handrail grips
Usually, the concentration of salts in a person’s perspiration
provides enough conductivity to transmit a signal to the
receiver inside the display console. However, some people,
because of body chemistry or erratic heart beats cannot use
the touch-sensitive heart rate feature on the EFX. A chest
strap may provide better results.
Important: While exercising, do not grasp the touchsensitive handrail grips and wear the chest strap at the
same time. The touch-sensitive handrail grips override the
signals from the chest strap transmitter. If used together,
inconsistent readings may occur.
Using SmartRate
The SmartRate feature helps you monitor and maintain your
heart rate in the target zone best suited to your specific
needs. All 10 LEDs may light during a workout. When the
EFX detects a heart rate, a single LED blinks and indicates
the zone that your heart rate is in.
Important: To use the SmartRate feature, you must enter
your age during the setup phase of your exercise session.
The 10 LEDs in the SmartRate display are color-coded. A
pulsating orange LED indicates you are outside the
recommended heart rate target zone. Green LEDs indicate
when you are exercising within the recommended fat burn or
cardio fitness zones.
Owner’s Manual: Heart Rate Features16
Table 1 shows the percents used in calculating the heart rate
target zones. While your heart rate remains within these
zones, the corresponding lights blink and provide a visual cue.
The calculation used to determine your maximum aerobic heart
rate is (220 minus your age). When you multiply it by the
percent indicated in Table 1, you can understand the relationship between the pulsating LED and your target heart rate.
CAUTION: Your heart rate should never exceed 85% of
your maximum aerobic heart rate or go above PEAK. If it
does, immediately reduce your strides per minute, adjust
the CrossRamp, or resistance to return your heart rate to
your physician-recommended target zone.

Exercise to Your Target Heart Rate
A dedicated window displays your heart rate while
exercising. To view your heart rate (beats per minute) on the
display, either wear a chest strap or grasp both touchsensitive handrail grips.
The Precor web site (www.precor.com) has several
suggestions for workouts with varying levels of intensity. It
provides many workout details that include the appropriate
target heart rate.
Heart Rate Analysis
Every time you complete a program using the chest strap or
touch-sensitive handrail grips, the EFX provides a heart rate
analysis after the workout summary.
Your average heart rate appears followed by the maximum
heart rate achieved during your workout. A third display
appears, if you entered your age, and indicates the amount of
time your heart rate remained between the target zones
shown.
The EFX includes a program that lets you exercise based on
a specified target heart rate. As you exercise, the Basic HRC
Program monitors your heart rate and automatically
maintains it within a few beats per minute (bpm) of your
selected target.
To use this program, press the PROGRAMS - HEART RATE
key. For more information, refer to Programs.
Owner’s Manual: Heart Rate Features18
The heart rate analysis is based on how often your heart rate
signal is received while exercising. If you use the chest strap,
the average heart rate will be more accurate than if you
occasionally grasp the touch-sensitive handrail grips.
