TRAP
The treadmill is equipped with telemetry, a heart rate monitoring system in which electrodes, pressed against the
skin, transfer heart rate signals to the treadmill console. These electrodes are attached to a telemetry heart rate
chest strap that the user wears during the workout. The chest strap is included with the treadmill.
See the diagram below for correct positioning of the strap. The electrodes (A), which are the two grooved surfaces on
the underside of the strap, must remain wet to transmit accurately the electrical impulses of the heart back to the
receiver. Moisten the electrodes. Then, secure the strap as high under the chest muscles as possible. The strap
should be snug, but comfortable enough to allow for normal breathing.
The transmitter strap delivers an optimal heart rate reading when the electrodes are in direct contact with skin.
However, it also functions properly through a thin layer of wet clothing.
If it becomes necessary to re-moisten the chest strap electrodes, grasp the center of the strap, pull it away from the
chest to expose the two electrodes, and moisten them.
