True Fitness 400 Series Treadmill User Manual


 
their speed or grade at anytime. The warm-up stage is not
predetermined by the amount of time input prior to workout,
and the user may take as much time as they wish to
approach their target heart rate. The warm-up stage ends
when the user’s heart rate is 10 beats below the pre-set
target heart rate.
At this point, the user enters the Heart Rate Control stage
and the treadmill’s computer takes control of both the speed
and grade (hands free).
The treadmill software gradually increases the user’s heart
rate to within 10 beats of the target heart rate.
In the situation where workload needs to be increased in
order to elevate the heart rate, the speed will be increased
first in 1/10 mph increments.
If needed, the speed will continue to increase up to the
pre-set maximum. If the user still requires additional
workload to raise the heart rate, the grade will be raised in
.5% increments up to the maximum pre-set grade (unless zero
grade was entered).
Conversely, whenever the workload needs to be reduced in
order to lower the heart rate, the grade will always be
reduced first. The grade will be reduced to zero (if required),
before speed is reduced.
