Electrode Areas

Pull the

3 sensor unit away from

your body a few inches and locate the two

electrode

areas on the inner side. Using a saline solution such as saliva or contact lens solution, wet both electrode areas. Return the sensor unit to a posi- tion against your chest.

CHEST PULSE SENSOR TROUBLE-SHOOTING

If the chest pulse sensor does not function properly, or if the displayed pulse is excessively high or low, try the trouble-shooting steps below.

•Make sure that the chest pulse sensor is under your clothing, against your skin, and as high under the pectoral muscles or breasts as is comfortable. Note: If the chest pulse sensor does not function when positioned as described, try moving it slightly lower or higher on your chest.

•Make sure that the logo on the sensor unit is facing forward and is right-side-up.

•Each time you use the chest pulse sensor, use saline solution such as saliva or contact lens solution to wet the two electrode areas on the sensor unit (see the drawing at the top of this page). If pulse readings do not appear until you begin perspiring, re-wet the elec- trode areas.

•As you walk or run on the treadmill, make sure that you are near the center of the walking belt and within arm’s length of the console. For the console to dis- play pulse 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. Pulse read- ing problems may be caused by medical conditions such as premature ventricular contractions (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 magnetic interference may be causing a problem, try relocating the treadmill.

•If the chest pulse sensor still does not function prop- erly, test the chest pulse sensor in the following way:

Hold the chest pulse sensor and place your thumbs over the electrode areas as shown above.

Next, hold the chest pulse sensor near the console. While holding one thumb stationary, begin tapping the other thumb against the electrode area at a rate of about one tap per second. Check the pulse reading on the console.

•If the chest pulse sensor does not function properly after you have followed all of the above instructions, the battery should be replaced in the following way:

Locate the battery cover on the back of the sensor unit. Insert a coin into the slot in the cover, turn the cover counterclock- wise, and remove the cover.

Remove the old bat-
tery and insert a new
CR 2032 battery.
Make sure that the	CR 2032
battery is turned so
	Battery
the writing is on
top. Replace the
battery cover and
turn it clockwise to
close it.

CHEST PULSE SENSOR CARE

•Dry the chest pulse sensor after each use. The chest pulse sensor is activated when the electrode areas are wetted and it is put on; the chest pulse sensor shuts off when it is removed and the elec- trode areas are dried. If the chest pulse sensor is not dried after each use, it may remain activated longer than necessary, 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 the chest pulse sensor 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.
