SUPPLYING POWER TO THE EFX534
The EFX does not require an electrical power connection. It has an internal battery that is recharged every time a user works out for a reasonable period of time. A pedaling speed above 40 strides per minute must be maintained for several seconds before the Precor banner appears on the display.Once the banner appears, the user can press QuickStart or Enter to begin working out. For more information, refer to page 34, Exercising on the EFX.
TESTING THE HEART RATE DISPLAY
If you have purchased the optional POLAR® chest strap, verify that the heart rate display is operational before customers begin using the machine.
Note: To conduct electrical impulses from a user’s heart, the electrode strips on the chest strap must be in contact with the user’s skin. Usually, the concentration of salts in a person’s perspiration provides enough conductivity to transmit a signal to the receiver in the display console. However some people, because of body chemistry or erratic heart beats cannot use the heart rate feature on the EFX. To purchase a POLAR® chest strap, refer to Obtaining Service on page 7.
