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.

CAUTION: Do not allow children on the EFX. Be aware that injuries can occur from roller arm movement. Always use the locking pin to secure the roller arm when the EFX is not in use.

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.
