•To conduct the electrical impulses from your heart, the chest strap’s electrodes require a certain percentage of salts and minerals in the water used to wet them. The electrodes continue to transmit your heart rate reading as long as they are in contact with your skin and your skin is providing enough moisture through your perspiration to keep the electrodes wet. However, if the concentration of salts in your perspiration is not high enough to conduct electrical impulses and send them to the receiver, your heart rate reading will appear erratic or not appear at all. Some people cannot use the heart rate feature because they do not have the proper body chemistry.
•Do not use the chest strap if you are taking any medication or have a cardiac pacemaker. Inaccurate heart rate readings can occur due to medication or electrical impulses from the cardiac pacemaker.
•Stretching or bending the electrode strips on the chest strap may cause the strips to lose their conductivity. Handle the chest strap with care.
•After extensive use, the chest strap (transmitter) may wear out, causing inaccurate heart rate readings. With every use, check the strap for excessive wear and replace it or the battery if necessary. See Obtaining Service on page 23.

Information Regarding Regulatory Requirements
FCC Federal Communications Commission, Part 15
The EFX5.21s has been tested and it complies with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against detrimental interference in a residential installation. The EFX generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the owner’s manual instruc- tions, may cause harmful interference to radio communications. However, even with following the owner’s manual instructions, there is no guarantee that interference will not occur in a particular installation.
If the EFX does cause interference to radio or television reception, which can be determined by pressing the power switch to 0 (OFF) and then I (ON), you are encouraged to try to correct the interference using one or more of the following measures:
•Reorient or relocate the receiving antenna for your TV, radio, VCR, etc.
•Increase separation between the EFX and the receiver (TV, radio, etc.).
•Connect the EFX into a different power
•Consult your dealer or an experienced radio/TV technician for help.
CAUTION: Per the requirements of the Federal Communications Commission, changes or modifications to this product, not expressly approved by Precor, could void the user’s authority to operate the product.
