Read the following before using the heart rate or 
SmartRate features.

•

Consult your physician before engaging in any vigorous 
exercise. Do not use the heart rate programs until 
authorized by your physician.

•

Know your heart rate and your physician-recommended 
heart rate target zone. 

Note: While exercising, you must grasp both touch-
sensitive grips for a minimum of five to ten seconds to 
transmit your heart rate to the display.

Note: Handheld heart rate performance may vary based on 
a user’s physiology, fitness level, age, and other factors. 
You may experience an erratic readout if your hands are 
dry, dirty, or oily, or if the skin on your palms is especially 
thick. Wearing hand lotion can also cause an erratic 
readout. 

To use the handheld heart rate feature place the palm of 
your hands directly on the metal heart rate sensors on the 
unit’s handlebars. To ensure a more accurate heart rate 
readout, make sure you follow these tips. 

•

It takes a number of consecutive heartbeats (15-20 
seconds) for your heart rate to register. 

•

When gripping the sensors, do not grip tightly. Keep a 
loose, cupping hold. Holding the grips tightly can make 
it difficult to read your heart rate. 

•

Make sure that the sensors are clean to ensure proper 
contact can be maintained. 

•

As you work out, your perspiration will help in 
transmitting your heart rate signal. If you are having 
difficulty using the handheld grips to determine your 
heart rate, try the sensors again later in your workout to 
see if you can get a heart rate signal.
