Exercise Stress Testing
The exercise test advances automatically through the exercise stages unless
the operator manually overrides the test.
NOTE:
When the stages in the treadmill protocol have durations other than infinite,
the exercise test advances from stage to stage automatically. However,
you can press
Exercise (on the treadmill controller keyboard) at any time
to manually advance to the next exercise stage.
3. Manually adjust the treadmill's speed and grade, or the ergometer's load, as
necessary.
You can adjust the speed, grade, or load in the following ways. However, once
you press these keys, the pre-programmed protocol becomes inactive: you must
manually control the speed and grade during the remainder of the exercise
and recovery phases.
• Press Speed W + (to increase speed) within 5 seconds of your last workload
change.
• Press Speed W – (to decrease speed) within 5 seconds of your last workload
change.
• Press Grade + (to increase grade) within 5 seconds of your last workload
change.
• Press Grade – (to decrease grade) within 5 seconds of your last workload
change.
