Using the EFX
As simple as using the EFX might seem, you should read this section so that you can use it safely
and effectively. This section of the owner’s manual provides the basic information you need for
exercising on your EFX, including the following:
• locating the ON and OFF switch
• removing the locking pin
• identifying and understanding features on the display console
• changing the unit of measure and displaying the scrolling speed
Note: Instructions explaining how to use the Precor Heart Rate Option and information regarding
the Heart Rate Control Course appear in another section:
Using the Precor Heart Rate Option.
Locating the ON and OFF Switch
Use the I/0 (ON/OFF) power switch to turn the unit I (ON) or 0 (OFF). This switch is located at the
rear of the unit, near the power cord.
Removing the Locking Pin
The locking pin secures the roller arm and keeps it from traveling up or down the ramp. Pull firmly
on the pin to slide it out of the ramp. The lanyard that is attached to the locking pin and ramp,
helps keeps the locking pin nearby.
Note: The ramp on the EFX is inactive until the foot pedals complete one revolution (one complete
stride). When you begin a workout, remove the locking pin and step onto the foot pedals. Once the
foot pedals are set in motion and you complete one revolution, you can change the ramp level.
Understanding the Display Console
The display console lets you control your EFX. As you work out, its features provides constant
feedback about your progress. Information about the ramp, resistance, elapsed time, strides per
minute, total strides, total caloric burn, and heart rate (if you use the Precor Heart Rate Option) is
available at any time. When you use the Precor Heart Rate Option, the POLAR
®
chest strap that you
wear transmits a signal which is displayed numerically (when the Heart Rate indicator is lit) on the
display console.
The EFX5.21si provides several courses engineered to target lower-body muscles and enhance
cardiovascular conditioning. In addition, the ability to design your own custom courses (CST1 or
CST2) also exists. For more information, refer to
Creating Custom Courses
.
Note: Informative messages scroll across the display and prompt you to enter specific information
before a workout. These messages request information and action. Other scrolling messages can
appear and explain problems that may arise while you are using the EFX. Some problems you can
solve. Other problems may require a qualified service technician. For service questions, please call
a Precor authorized service center. For the service center nearest you call, 1-800-4-PRECOR.
