The heart rate is displayed in beats per minute .
The computer signals a warning if the preselected value is exceeded . The
display starts blinking .

For all programs with the exception of Program 9 (Individual
Heart Rate Control), 10, 11 and 12 (Heart Rate Control) the
optimal target heart rate is calculated (TARGET HR). The computer
calculates the target heart rate as a value of 70 % of the maximum
heart rate.

Measurement via hand pulse sensors: Die Sen-
sors to record heart rate from the palms are located
on the handlebars . For recording to take place
both palms have to be in contact with the sensors
simultaneously [1] .
Measurement via chest strap (optional): Heart
rate measurement takes place through sensors
integrated in the chest strap . There is a wireless
signal to a receiver in the computer . The chest strap
has to be worn correctly and the sensors may need
to be moistened [2] . This measurement is constant
and accurate .
All commonly used analog chest straps, with a frequency of 5,4 – 5,7 Hz can
be used .
Important information to determine your correct and optimal
heart rate as well as the heart rate's proper application
during the work out can be found in the training guide on the
ENERGETICS CD "Personal Training Instruction".
Hand pulse sensor record the variation in resistance which
is created by the pulsation of the blood flowing through
the palms. Movement on the hand grips, friction, moisture
and perspiration will influence the transmission. There are among
people appreciable physiological differences in the characteris-
tics of the resistance change. For some people the resistance is to
weak to even be measured. In this case the computer will show
no heart rate.
All these factors influence the measurement, which makes it
imprecise and it should only be used for orientation.
If the hands are dry at the beginning of the workout the hand
pulse sensors might not pick up a signal at all or register a faulty
one. Usually it is sufficient to moisten the palms to correct this.
Electromagnetic influence factors
All electronic devises such as T. V., computer etc. are surrounded
by electromagnetic fields or respectively use wireless transmis-
sion like a cordless telephone. The receiver in the computer can
only conditionally differentiate between a "good" and a "bad"
signal. Interfering signals from another source can disturb the
recording of the heart rate. Your exercise equipment should be
