•Keep hands away from all moving parts.
•The pulse sensors are not medical devices. Various factors, including the user’s movement, may affect the
accuracy of heart rate readings. The pulse sensors are intended only as exercise aids in determining heart
rate trends in general.
•Do not attempt to use your equipment for any purpose other than for the purpose it isintended.
•Wear proper shoes. High heels, dress shoes, sandals or bare feet are not suitable for use onyour
equipment. Quality athletic shoes are recommended to avoid leg fatigue.

bike may be affected. Such conditions are not covered under your warranty. If you
suspectthe voltage is low, contact your local power company or a licensed electrician for
proper testing.
•NEVER expose this exercise bike to rain or moisture. This product is NOT designed for

environmental ratings are 40-120 degrees Fahrenheit, 95% humidity non-condensing(no
water droplets forming on surfaces).
Important Operation Instructions
•NEVER operate this exercise bike without reading and completely understanding the
results
of any operational change you request from thecomputer.
•Understand that changes in resistance do not occur immediately. Set your desired level on
the computer console and release the adjustment key. The computer will obey the

Hand Pulse Grips
Your U15 Exercise bike has built-in hand pulse grips located on the handles next toeither
side of the seat. Tomonitor your heart rate, simply grasp both hand pulse gripsensuring
steady contact is made between your hands and the metal contact pads for at least10
seconds. Once the machine has detected your pulse, the heart rate will be display inthe
“Pulse” section on your screen.
Note: There are significant individual differences in the heart rate of normal adults at rest, with
an average of about 75 beats/min (between 60-100 beats/min). Factors like age, gender, and
other physiological conditions will affect heart rate. The resting heart rate of newborn babies
is fast, reaching more than 130 beats per minute. Among adults, the heart rate ofwomen
is generally slightly faster than that of men. Heart rate will slow down during quiet orsleep
and speed up during exercise or emotional excitement. Under the influence of certain drugs
or neurohumoral factors, the heart rate will increase ordecrease.
People who do physical labor or physical exercise daily oftenhave
a slower heart rate.
Wearing A Chest Strap
(Sold Separately)
1. Attach the transmitter to the elastic strap using the interlocking button.
2. Adjust the strap as tightly as possible as long as the strap is not too tight toremain
comfortable.
3. Position the transmitter with the logo centered in the middle of your
torso facing away from your chest (some people must position the
transmitter slightly left of center). Attach the final end of the elastic
strap by inserting the round end and, using the locking parts,secure
the transmitter and strap around your chest.
4. Position the transmitter directly below the pectoral muscles.
5. Sweat is the best conductor to measure very minute heart beat electrical signals.
However, plain water can also be used to pre-wet the electrodes (2 ribbed oval areas
on the reverse side of the belt and both sides of the transmitter). It’s also recommended
that you wear the transmitter strap a few minutes before your
work out. Some users, because of body chemistry, have a more difficult time in
achieving a strong, steady signal at the beginning. After “warming up”, thisproblem
lessens.
6. Your workout must be within range - distance between transmitter/receiver –to achieve
a strong steady signal. The length of range may vary somewhat but generally stayclose
enough to the console to
maintain good, strong, reliable readings. Wearing the transmitter directly on bare skin
assures you of proper operation. If you wish, you may wear the transmitter over ashirt.
Todo so, wet the areas of the shirt that the electrodes will rest upon.
Note: The transmitter is automatically activated when it detects activity from the user’s heart. Additionally, it au-
tomatically deactivates when it does not receive any activity. Although the transmitter is water resistant,moisture
can have the effect of creating false signals, so you should take precautions to completely dry the transmitter.
