CORRECTING INCONSISTENT HEART RATE READINGS
If you have purchased the Precor Heart Rate Option and the Precor optional
heart rate receiver is installed in the electronic console, the EFX544 should be
able to pick up your heart rate signal. However, if messages appear on the
display regarding heart rate errors, stop your workout and take the following
steps:
Important: Be sure that the heart rate being displayed correlates to your
“normal” heart rate during exertion. Also, read the information found in the front
section Precor Heart Rate Option—Safety Guidelines .
1. Check with the club manager to make sure that the EFX544 contains the
heart rate receiver inside the electronic console display.
2. Make sure that the electrodes on the chest strap are moist and placed
properly against your skin. Check to be sure that the strap is comfortably
tight around your chest and centered in the middle of your chest. Refer to the
section in your Precor Heart Rate Option Owner’s Manual titled, Wearing
the Chest Strap Transmitter .
3. Be sure that you are within 3 feet of the electronic console and facing toward
it. Allow a few seconds for the receiver to display your heart rate on the
electronic console’s display.
4. Make sure that the EFX544 is turned ON.
Most often, when the chest strap fails to transmit a heart rate signal, the cause
is incorrect placement or conduction of the chest strap electrodes. A spray is
included with the Precor Heart Rate Option that, when sprayed onto the
electrodes, can enhance the conductivity. For other problems, check with your
local servicer, he or she should have a chest strap/heart rate simulator that can
test your equipment to make sure that it is operating properly.
If you have taken the steps above and still get erratic readings, you may need
to replace the chest strap transmitter or its battery. Refer to your Precor Heart
Rate Option Owner’s Manual . If you have difficulty correcting a problem, call your
local servicer.
