For a chest strap:
Make sure the strap is fastened, positioned, and

moistened correctly.
Make sure the strap is compatible with the

equipment. It must be a 5 kHz strap. Heart rate
straps that function at other frequencies, and
Bluetooth-based straps, are not compatible with
this equipment.

Precor cannot guarantee the accuracy of any readings
you may get, but for best results, follow these tips.
The touch-sensitive grips may not be making secure
contact. Try the following solutions:
Make sure that your hands are clean, slightly

moist, and positioned as described earlier in this
table.
 Try using a chest strap instead of the grips.
If you are trying to use the grips and an active chest
strap at the same time, choose one or the other. Either
do not grasp the touch-sensitive grips, or remove or
turn off the chest strap.
