CAUTION:
The safety key must be in place on the treadmill console, and should be attached to the user’s clothing. The treadmill will
not operate if the safety key is not attached to the console.
HEART RATE MONITORING:
This treadmill can monitor a user’s heart rate using either a Polar® compatible chest strap or the metal grips on the hand
rails (called contact heart rate or CHR pads). A chest strap transmits the user’s heart rate to the treadmill via radio, and the
CHR pads connect to a special computer circuit to extract the user’s heart rate.
Chest Strap Heart Rate Monitoring:
Although this treadmill functions fine without using the heart rate monitoring feature, this
kind of monitoring gives valuable feedback on the user’s effort level. Chest strap monitoring
also allows users to use Heart Rate Control, the most advanced exercise control system
available.
When users wear a Polar® compatible transmitter strap, the treadmill will display the user’s
heart rate as a digital beats-per-minute (bpm) readout.
The transmitter strap should be worn directly against the user’s skin, about 1-2 inches
below the pectoral muscles/breast line. Women should be careful to place the
transmitter below their bra line.
Initially the transmission signal for heart rate may be erratic or non-existent. Some moisture is
necessary between the strap and the user’s skin for proper transmission. Sweat from exercise
works best, but ordinary tap water may be used prior to the workout if desired.
A Note on Chest Strap Heart Rate Monitoring:
The chest strap produces a radio signal that the treadmill reads and registers as the user’s heart rate. The accuracy of a
reading may be affected when outside interference is present.
Contact Heart Rate (CHR):
The CHR system will let the user monitor their heart rate without wearing a chest strap. When using the CHR system
users should gently grasp the CHR pads with both hands. Within 30 seconds, the user’s heart rate should be displayed as a
digital bpm readout (during the first 30 seconds the system is analyzing and locking in the user’s heart rate). Users should
exercise with smooth body motions and breathe regularly. It is best to avoid talking while using the CHR system, as
talking will cause unrepresentative heart rate spikes of 5 to 10 bpm. To ensure an accurate reading, the user’s hands should
be clean, free of both dirt and hand lotions.
*For increased safety and accuracy the CHR system should only be used at speeds of 4 mph or lower (CHR readings are
less accurate due to large muscle movements above this speed).
A Note on CHR Accuracy:
CHR monitoring may be less accurate than chest strap monitoring since the heart rate signals are much stronger at the
chest. When using a HRC workout, it is best to use a chest strap because of the stronger and more accurate readings.
CAUTION:
Do not use the contact heart rate grips as a handlebar during a workout.
