• Keep the equipment dry. Although the chest strap should not be immersed in water, wetting the
electrodes and your chest will improve the initial performance. Note that perspiration on the
chest strap during workouts is normal and actually enhances the signal being sent from the
chest strap’s transmitter.
• 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 if necessary. See

Information Regarding Use in the U.S.A. and Canada
Federal Communications Commission, Part 15
The M9.25i treadmill has been tested and found to comply 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 harmful interference in a residential installation. The M9.25i treadmill generates, uses, and
can radiate radio frequency energy and, if not installed and used in accordance with the owner’s
manual instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation.
If the M9.25i treadmill does cause harmful interference to radio or television reception, which can be
determined by turning the M9.25i treadmill OFF and 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 M9.25i treadmill and the receiver (TV, radio, etc.).
• Connect the M9.25i treadmill into a different power outlet—on a dedicated circuit different from
the one used by the receiver (TV, radio, etc.). No other appliance should be plugged into the
same power outlet that the treadmill is connected to.
• Consult your dealer or an experienced radio/TV technician for help.
WARNING
Per FCC rules, changes or modifications not expressly approved by Precor, could void the user’s
authority to operate the equipment.
