Using the Wireless Heart Rate Receiver
In general, a wireless heart rate chest strap is the most accurate and convenient method of detecting and monitoring a heart rate signal and is
a considerable upgrade from the touch type heart rate sensors. Occasionally, certain factors can negatively affect the accurate transmission of
the heart rate signal. WiFi networks, cordless telephones and large electrical appliances may degrade or corrupt the signal so that the rate
appears erratic or impossibly high. The only remedy for such a symptom is to isolate the unit from potential disturbances. Additionally, a
person's body chemistry or lack of perspiration can prevent the chest strap from providing a strong or accurate heart rate signal
A wireless telemetry heart rate receiving system is one feature found on this unit. In order for the console to detect and display your heart
rate wirelessly, four (4) conditions must be present:

A compatible heart rate chest strap transmitter (not included) must be functioning and worn. For proper function of the chest strap,
please refer to the manufacturer's instructions. Non‐coded transmitters such as the Polar model T31 and T34 are examples of
wireless chest straps known to be compatible with this unit.

The unit must be powered on.

A workout program must be running.

The user is within three (3) feet of the console.
Calculated Maximum Heart Rate & Target Training Zone
Your target heart rate depends primarily upon your age. It is important to work within a
safe and productive zone, for if the exercise intensity is too low or too high, only modest
gains will be made in strength and cardio‐vascular fitness. A workout at a very low intensity
will not offer maximum benefits. Conversely, if the workout intensity is too high, injury or
fatigue may slow the progression of your exercise goals as the body attempts to recover.
Note: It is most effective to train at a heart rate between 60% and 85% of your
maximum heart rate. Maximum heart rate is calculated as a percentage
of your maximum heart rate (estimated as 220 BPM minus your age).
To calculate your maximum heart rate and find the appropriate target training zone, use the
following formulas. The following estimation would be relevant for a 35 year‐old user:

220 – 35 = 185 BPM

0.60 x 185 = 111 BPM

0.85 x 185 = 157 BPM

(220 – Age = Calculated Maximum Heart Rate in Beats‐per‐minute/BPM)
(60% of 185 BPM [Calculated Maximum Heart Rate] = 111 BPM)
(85% of 185 BPM [Calculated Maximum Heart Rate] = 157 BPM)
