3.Another scrolling prompt appears to ask you to verify your lower heart rate limit. Use the or keys if you wish to override the recommended heart rate. Press Enter.

4.The software verifies that it detects the heart rate signal. Move the foot pedals to begin your workout. A 3-minute warm-up period helps get your heart rate into its target zone. The HRC program automatically takes over once your heart rate is in the target zone or the 3 minutes elapse.

Note: If your heart rate cannot be detected or no heart rate is transmitted for more than

3 minutes, the Heart Rate Control Course begins, but its operation is the same as manual mode. Every 30 seconds the program checks for a heart rate.

5.The system automatically adjusts the resistance level to keep your heart rate within the target zone. If, during your workout, your heart rate falls outside of the target range, the system automatically overrides the resistance settings to bring your heart rate to within the target zone.

Important: While using the HRC program, strive to maintain a constant stride rate (above 100 spm) to get the best aerobic and cardiovascular workout. Use the Smart Rate display for visual cues to help keep your heart rate in its target zone.

6.When you reach the time limit, the system automatically enters a cool-down period. You can change the resistance and ramp level by pressing the or keys.

During your cool down, the displays on the console continue to appear. The Time display counts down, so you know how much time is remaining in cool down. It is recommended that you cool down for at least 3 minutes. This helps your heart rate to return to a normal rhythm.

7.At the end of the cool down period, your FINAL workout statistics appear. The display returns to the Precor banner. Hold onto the handrails while you step off the EFX and turn it 0 (OFF). Refer to Pause/Hold to Reset key on page 8 for more information.

Correcting Inconsistent Heart Rate Readings

If you have purchased the Precor Heart Rate Option and the EFX cannot pick up your heart rate signal or messages appear on the display regarding heart rate errors, stop your workout and take the following steps:

Important: Be sure that the optional heart rate receiver is installed in the display console. Also, review the information found in the Safety Information, Precor Heart Rate Option—Safety Guidelines.

1.Make sure that the electrodes on the chest strap are moist and placed properly against your skin. Sometimes, due to body chemistry, the chest strap cannot successfully detect and transmit your heart rate. If this occurs, use the electrolyte spray that accompanies your Precor Heart Rate Option package. Follow the directions on the bottle. After spraying the electrode strips on the chest strap, check to be sure that the strap is comfortably tight around your chest and centered in the middle of your chest. Refer to Diagram 11 on page 17.

2.Be sure that you are within 3 feet of the display console and facing toward it. Allow a few seconds for the receiver to display your heart rate on the display console.

3.Make sure that the EFX is turned I (ON).

If you have taken the steps above and still get erratic readings, you may need to replace the POLAR® chest strap.

Most often, when the chest strap fails to transmit a heart rate signal, the cause is incorrect placement or conduction of the chest strap electrodes. If necessary, check with your local servicer, he or she has a chest strap/heart rate simulator that can test your equipment to make sure that it is operating properly.
