the intensity level during an EXERCISE interval. The intensity level shown
during an EXERCISE interval is indicative of your current speed. However, the
current speed during a REST interval is equal to a scaled percentage of the
displayed intensity level. Note that the program profile does not change at any
time during the workout session.
The Constant Heart Rate Program
The Constant Heart Rate program maintains a chosen target heart rate by
automatically varying the climbing speed during each workout. The default
target heart rate is equal to 70% of your maximum heart rate which is calcu-
lated by the following equation: 220 - (Age) x .70. Choose a different target
heart rate (between 80 and 180 beats per minute) at any time during the
workout by using the numeric keypad to enter the new target heart rate,
followed by the [ENTER] key. The following messages may be shown during a
workout:
• “ CHECK HR BELT ” - The heart rate signal has been missing for
the last 30 seconds in telemetry signal detection.
• “HR BELT NEEDED” - No telemetry belt signal has been sensed
during the initial setup time.
• “HOLD HR SENSORS” - In contact heart rate signal situations
this message will come every 30 seconds to prompt the user to
hold the sensors.
• “ HR MODE DISABLED ” - No heart rate signal is allowed due to
the set up option that was chosen. Heart rate monitoring is not
possible.
