Heart Rate Control Important Points 2-20

•The Heart Rate Monitor strap provided with your treadmill should be worn directly against youskin,1-2inchesbelowthepectoral muscles/breast line. Initially the transmission signal for your heart rate may be erratic or nonexistent. Perspiration on your skin is necessary for proper transmission. In most cases, by the end of your warm-up, transmission becomes consistent and accurate. If not, saline solution should be used to moisten the sensors on the back of the strap. Women should be careful to place the ` transmitter below their bra line. If the transmitter strap is adjusted or moved while exercising, communication may be temporarily affected.

•If communication is lost for 30 seconds, the treadmill will automatically shut off. It is important to keep the transmitter adjusted properly.

•The transmitter emits a fairly weak signal to the receiver, so interference from more powerful airwaves (everything from other exercising equipment to airplanes) is not uncommon. The good news is that interference is usually quite brief. If you continue to have intermittent heart rate display problems, consult your local service technician. The problem may be with the transmitter batteries.

•Oxygen intake directly affects your heart rate. To prevent your heart rate from spiking up, maintain a constant rate of oxygen intake. Maintaining a fluid motion while walking or running and refraining from talking helps to keep your heart rate from spiking.

Note: Talking while in the HRC stage can cause your heart rate to rise independent of your workload and cause the software to make necessary changes. This will cause inappropriate speed and/or grade changes, and affect the efficiency of your HRC workout.

•A grounded outlet is critical for the HRC system to function properly.

•If erroneous heart readings are displayed above the target selected, you can pull the transmitter portion away from your chest for several seconds. This will keep you from exiting HRC.

•Two users wearing the same kind of transmitter at the same time, in close proximity, may cause false heart rate display readings.

•Use only the transmitter provided with your TRUE HRC Treadmill, or a Polar standard transmitter.

•Use dedicated 110 VAC, grounded outlet to help prevent interference.

Your TRUE HRC Treadmill is designed to meet the needs of both walkers and runners by adjusting speed and grade accordingly:

•To raise your heart rate in the HRC mode, speed will always increase first, until you reach your maximum speed, followed by grade (if grade is used in the workout).

•To lower your heart rate in the HRC mode, grade will always decrease first, until you reach 0% grade, followed by speed (if grade is used in the workout).

•Each change of speed is .1 MPH increments.

•Each change of grade is .5% grade increments.

•For examples of workout maximum speed and maximum grade, refer to program charts on page 2-9.

HEART RATE SAFETY PARAMETERS

Your TRUE HRC Treadmill computer software is programmed with the following safety parameters:

•If your heart rate exceeds your target by 12 beats, there will be a 30% MET reduction in workload to reduce your heart rate.

•If your heart rate exceeds your target by 20 beats, the unit will automatically shut off as a precautionary measure. (Be cautious when selecting your target heart rate so the 20 beat variance will not exceed your maximum heart rate as determined by your physician).
