HOW to USE the Chest Pulse Sensor

HOW TO PUT ON THE CHEST PULSE SENSOR

The chest pulse sensor consists of two components— the chest strap and the sensor unit.

Insert the tab on one end of the chest strap into the hole in one end of the sensor unit, as shown in the inset drawing above. The tab should be flush with the front of the sensor unit.

Next, wrap the chest pulse sensor around

your chest and attach the other end of the chest strap to the

sensor unit. Adjust the length of the chest strap, if neces-

sary. The chest pulse

sensor should be under your clothes, tight against your skin, and as high under the pectoral muscles or breasts as is comfortable. Make sure that the logo on the sensor unit is facing forward and is right-side-up.

Pull the sensor unit away from your body a few inches and locate the two electrode areas on the inner side (the electrode areas are covered by shallow ridges). Using saline solution such as saliva or contact lens so- lution, wet both electrode areas. Return the sensor unit to a position against your chest.

CHEST PULSE SENSOR CARE AND MAINTENANCE

•Thoroughly dry the chest pulse sensor after each use. The chest pulse sensor is activated when the electrode areas are wetted and the heart rate monitor is put on; the chest pulse sensor shuts off when it is removed and the electrode areas are dried. If the chest pulse sensor is not dried after each use, it may remain activated longer than nec- essary, draining the battery prematurely.

•Store the chest pulse sensor in a warm, dry place. Do not store the chest pulse sensor in a plastic bag or other container that may trap moisture.

•Do not expose the chest pulse sensor to direct sunlight for extended periods of time; do not expose it to temperatures above 122° F (50° C) or below 14° F (-10° C).

•Do not excessively bend or stretch the sensor unit when using or storing the chest pulse sensor.

•Clean the sensor unit using a damp cloth—never use alcohol, abrasives, or chemicals. The chest strap may be hand washed and air dried.

CHEST PULSE SENSOR TROUBLESHOOTING

The instructions on the following pages explain how the chest pulse sensor is used with the con- sole. If the chest pulse sensor does not function properly, try the steps below.

•Make sure that you are wearing the chest pulse sen- sor as described at the left. Note: If the chest pulse sensor does not function when positioned as de- scribed, move it slightly lower or higher on your chest.

•Use saline solution such as saliva or contact lens solution to wet the two electrode areas on the sensor unit. If heart rate readings do not appear until you begin perspiring, rewet the electrode areas.

•As you walk or run on the treadmill, position your- self near the center of the walking belt. For the console to display heart rate readings, the user must be within arm’s length of the console.

•The chest pulse sensor is designed to work with people who have normal heart rhythms. Heart rate reading problems may be caused by medical conditions such as premature ventricular contrac- tions (pvcs), tachycardia bursts, and arrhythmia.

•The operation of the chest pulse sensor can be affected by magnetic interference caused by high power lines or other sources. If it is suspected that this is a problem, try relocating the treadmill.
