Owner's Manual: Advanced Programming and Troubleshooting
What to Do
You should not attempt to
service the treadmill
except for maintenance
tasks as described in this
manual. The treadmill
does not contain any
user-serviceable parts
that require lubrication.
For information about
product operation or
service, see the Precor
web site at
www.precor.com. For
future reference, write
the model, serial number,
and date of purchase for
your unit in the space
provided. The serial
number is printed on a
label located on the front
panel, near the power
cord (Diagram 2).
Begin your workout and
your heart rate should
appear if you are wearing
a chest strap or holding
the touch-sensitive grips.
What appears
on the display Cause

Heart rate is not
detected when you
access the Heart
Rate Control
Programs.
Note: To conduct electrical impulses from a user's heart,
the electrode strips on the chest strap must be in contact
with the user's skin. Usually, the concentration of salts in a
person's perspiration provides enough conductivity to
transmit a signal to the receiver in the display console.
However, because of body chemistry or erratic heartbeats,
some people cannot use the heart rate feature.
What to Do
Be sure the chest strap is
moist, centered and in
direct program contact
with your skin. Stand
within three feet of the
display and face it. Allow
a few seconds
for the receiver to detect
a signal.
If using the touch-
sensitive handrail grips,
use both hands and make
sure your hands are
moist, not dry.
