Heart Rate Monitoring
CHAPTER ONE: BASIC OPERATIONS
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.

(CHR)
Contact Heart Rate
CHAPTER ONE: BASIC OPERATIONS
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.
CS Treadmill Owner’s Guide |
15 |
Contact Heart Rate
CHAPTER ONE: BASIC OPERATIONS
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.

Pre-Set Workouts
CHAPTER ONE: BASIC OPERATIONS
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
Changes in Grade
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.

CHAPTER ONE: BASIC OPERATIONS
These are True’s original four pre-set workouts. Changing the workout time stretches and compresses the workout profile, in ontrast to the four new pre-set workouts. Other differences are explained below in the individual workout sections.
Incline changes in varying amounts in contrast to the new Hills workout, which has hills of the same size all throughout the workout.
Very similar to Hill Intervals, with varying incline changes.
Similar to Speed Ramp, except both speed and grade change.
