Basic Heart Rate Control
This program computes your target heart rate based on the
calculation, 60% of 220 minus your age. The equipment
adjusts resistance and/or incline to maintain your target heart
rate while you work out.
When a heart rate signal is not received, a heart shape with a
question mark appears in the upper text display. Recheck your
hand grip on the handheld sensors or the placement of your
chest strap.

Note: For the unit to detect your heart rate, you must grip the
handheld heart rate sensors or wear a chest strap while
exercising. In the presence of both handheld and wireless
data, the handheld data takes precedence and displays.
Hill Climb
This preset program simulates hill climbing. The program is
fixed at 30 minutes on most equipment, and the resistance is
predetermined. Any increase or decrease made in one
program segment will increase or decrease all remaining
portions by the same amount.
