HOW TO PUT ON THE HEART RATE ONITOR
The heart rate
monitor consists of
a chest strap and a
sensor. Insert the
tab on one end of
the chest strap into
the hole in one end
of the sensor as
shown. Then, press
the end of the sen-
sor under the buckle
on the chest strap.
The tab should be
flush with the front
of the sensor.
The heart rate moni-
tor must be worn
under your clothes,
tight against your
skin. Wrap the heart
rate monitor around
your chest in the
location shown.
Make sure that the
logo is right-side-up.
Then, attach the other end of the chest strap to the
sensor. Adjust the length of the chest strap, if
necessary.
Pull the sensor away from your body a few inches and
locate the two electrode areas, which are covered by
shallow ridges. Using saline solution such as saliva or
contact lens solution, wet the electrode areas. Then,
return the sensor to a position against your chest.
CARE AND AINTENANCE
• Thoroughly dry the sensor with a soft towel after
each use. Moisture may keep the sensor activated,
shortening the life of the battery.
• Store the heart rate monitor in a warm, dry place.
Do not store the heart rate monitor in a plastic bag
or other container that may trap moisture.
• Do not expose the heart rate monitor to direct sun-
light 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 when
using or storing the heart rate monitor.
• To clean the sensor, use a damp cloth and a small
amount of mild soap. Then, wipe the sensor with a
damp cloth and thoroughly dry it with a soft towel.
Never use alcohol, abrasives, or chemicals to clean
the sensor. and wash and air dry the chest strap.
TROUBLESHOOTING
If the heart rate monitor does not function properly, try
the steps below.
• Make sure that you are wearing the heart rate moni-
tor as described at the left. If the heart rate monitor
does not function when positioned as described,
move it slightly lower or higher on your chest.
• If heart rate readings are not displayed until you
begin perspiring, rewet the electrode areas.
• For the console to display heart rate readings, you
must be within armʼs length of the console.
• If there is a battery cover on the back of the sensor,
replace the battery with a new battery of the same
type.
• The heart rate monitor is designed to work with peo-
ple who have normal heart rhythms. eart rate
reading problems may be caused by medical condi-
tions such as premature ventricular contractions
(pvcs), tachycardia bursts, and arrhythmia.
• The operation of the heart rate monitor can be
affected by magnetic interference from high power
lines or other sources. If you suspect that magnetic
interference is causing a problem, try relocating the
fitness equipment.

HOW TO USE THE ELLIPTICAL
HOW TO PLUG IN THE POWER CORD
This product must be earthed. If it should malfunc-
tion or break down, earthing provides a path of least
resistance for electric current to reduce the risk of
electric shock. This product is equipped with a power
cord having an equipment-earthing conductor and an
earthing plug. I PORTANT: If the power cord is
damaged, it must be replaced with a manufacturer-
recommended power cord.
1. Plug the indicated end of the appropriate power
cord into the receptacle on the elliptical.
2. Plug the power
cord into an
appropriate out-
let that is
properly
installed and
earthed in
accordance
with all local
codes and
ordinances.
DANGER: Improper connection
of the equipment-earthing conductor can
result in an increased risk of electric shock.
Check with a qualified electrician or service-
man if you are in doubt as to whether the
product is properly earthed. Do not modify
the plug provided with the product—if it will
not fit the outlet, have a proper outlet
installed by a qualified electrician.

the electrical components on the elliptical may
wear prematurely.
