This treadmill can monitor your heart rate using either a chest
strap or the metal grips on the hand rails (called contact heart
rate or CHR pads). A chest strap transmits your heart rate to
the treadmill via radio, and the CHR pads connect to a special
computer circuit to extract your heart rate.
Although this treadmill functions fine without using the heart rate
monitoring feature, this kind of monitoring gives you valuable
feedback on your effort level. Chest strap monitoring also allows
you to use Heart Rate Control, the most advanced exercise control
system available.
When you wear a Polar® or compatible transmitter strap, the
treadmill will display your heart rate as a digital beats-per-minute
(bpm) readout.
The transmitter strap should be worn
directly against your skin, about one inch
below the pectoral muscles/breast line (see
picture). Women should be careful to place
the transmitter below their bra line.
Some moisture is necessary between the
strap and your skin. Sweat from your exercise
works best, but ordinary tap water may be
used prior to your workout if desired.

The contact heart rate (CHR) system lets you monitor your heart
rate without wearing a strap.
Gently grasp the contact heart rate pads as shown.
When the system detects your hands, the Heart Rate label will
start flashing in time with your heart beat. During this time, the
system is analyzing and locking in your heart rate. Within about
15 seconds, your digital heart rate in beats per minute should be
displayed.
Important: The CHR System should only be used while walking
at speeds of 4 mph or lower. Above this speed the CHR accuracy is
unavoidably unreliable due to large muscle movements.

1. Exercise with smooth body motions.
2. Breathe smoothly and regularly, and avoid talking. (Talking
will cause unrepresentative heart rate spikes of 5 to 10
bpm.)
3. Grip the pads lightly, not tightly.
4. Make sure your hands are clean, free of both dirt and hand
lotions.
When using a Heart Rate Control workout, it is best to use chest
strap monitoring. These workouts work best with the extra
accuracy gained from a chest-contact heart rate monitoring
system.
A Note on CHR Accuracy
CHR monitoring may be a bit less accurate than a
chest strap, since the heart rate signals are much
stronger at the chest.
About 5% of the population cannot be picked up
by any CHR system. This is because their heart is
positioned in a more up-and-down manner in their
chest, as opposed to leaning over to one side.

Each workout has a four-minute warm up and a two-minute cool
down. Speed or grade changes stay in effect until the next change
is requested by the program. Changing the default workout time
adds or removes segments; it does not stretch or compress the
workout profile.
Change workout levels during your workout by pressing the
key for the workout you are using (its LED will be lit), adjusting
the numeric level, then pressing . Change to a new pre-set
workout during your workout by pressing any of the present
workout keys and pressing at your desired workout.
In a walking workout, all speeds are under 4 mph. Increasing
levels increases speed from 2 to 4 mph and grade from 4% to 10%;
speed and grade stay constant in the work section. Speed or grade
changes in the work section are permanent
Walking intervals with grade alternate between hills and nearly
flat in two-minute segments. Speed changes are permanent; grade
changes affect the current two-minute segment only.
