6-2 Heart Rate Monitoring
A. Hand Sensor System
During exercises, grasp the stainless steel sensors on the front handrail to check your heart rate.
Two sensors are located on each of the handrails. Contact must be maintained with all four sensors
to obtain a heart rate. The console displays a heart rate within 20 to 30 seconds of contact with the
sensors.
Do not attempt to grasp the sensors at speeds above 4.5 MPH, or 7.2 KPH. For these speeds, the
use of a heart rate chest strap is recommended.
B. The Optional Heart Rate Chest Strap
The treadmill is equipped with a heart rate chest strap sensor, 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 chest strap that the user wears during the workout. The chest strap is
optional, contact Magnum to purchase

Correct Positioning of the Strap and Wearing Method
S
ee the upper drawing 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 bare skin. It 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 re-moisten them. During the setup of a heart rate zone training workout, the user
will be required to enter a start-up speed. If a heart rate chest strap is not detected, the maximum
allowable speed is 4.5 mph(7.2km). If a heart rate chest strap is detected, the maximum speed is
15.6mph(25Km)
