Precor 9.21i owner manual Correcting Inconsistent Heart Rate Readings

4.The software verifies that it detects the heart rate signal and a prompt appears requesting that you press the SPEED ▲ key to begin your workout.

Important: Hold onto the handrail. If the treadmill is not already at 0% incline, it automati- cally returns to 0% incline.

5.Use the SPEED▼ or ▲ keys to control the running belt’s speed. The treadmill automatically adjusts the incline to keep your heart rate within the target zone. You can use the INCLINE or SPEED ▼ or ▲ keys any time during the 3-minute warm-up period to get your heart rate into its target zone. The program automatically takes over once your heart rate is in the target zone or the 3 minutes elapse. If, during your workout, your heart rate falls outside of the target range, the treadmill automatically overrides the incline (in 2% increments up to 10%) to bring your heart rate to within the target zone.

Note: If your heart rate cannot be detected or no heart rate is transmitted for more than 3 minutes, the Heart Rate course begins, but its operation is the same as Manual mode. Every 30 seconds the program checks for a heart rate.

6.When you reach the time limit, the treadmill automatically enters Manual mode so you can begin a cool-down period. You can change the speed and incline by pressing the ▼ or ▲ keys.

During your cool down, the displays on the console continue to appear. The TIME display counts up from zero, so you know how long you have been in the cool-down period. It is recommended that you cool down for at least 3 minutes. This helps your heart rate to return to a normal rhythm.

7.Hold onto the handrail and press the STOP key or press the SPEED ▼ key until the running belt slows to a gradual stop. The displays on the console freeze which lets you review your workout statistics. Straddle the running belt and remove the safety clip from your clothing. Step off the treadmill if you have finished your workout and turn it OFF.

8.To prevent unauthorized use, remove the magnetic safety key from inside the electronic console and store it in a safe place.

Correcting Inconsistent Heart Rate Readings

If you have purchased the Precor Heart Rate Option and the treadmill 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 electronic 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. The brand name of the strap should be upright and centered in the middle of your chest. Refer to Diagram 13 in the section titled, Wearing the Chest Strap Transmitter.

2.Make sure that the treadmill is turned ON and the magnetic safety key is secure.

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

If you have taken the steps above and still get erratic readings, you may need to replace the chest strap transmitter or its battery. For chest straps with batteries, refer to Changing the Battery in the Chest Strap.

Most often, when the chest strap fails to transmit a heart rate signal, the cause is incorrect placement or problems with the electrodes. 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.
