Hand Pulse Grips
Your SB4500 Fitness Bike has built-in hand pulse grips located on the handles next to either
side of the seat. To monitor your heart rate, simply grasp both hand pulse grips ensuring
steady contact is made between your hands and the metal contact pads for at least 10
seconds. Once the machine has detected your pulse, the heart rate will be display in the
“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 of women
is generally slightly faster than that of men. Heart rate will slow down during quiet or sleep
and speed up during exercise or emotional excitement. Under the influence of certain drugs
or neurohumoral factors, the heart rate will increase or decrease.
People who do physical labor or physical exercise daily often have
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 to remain
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”, this problem
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 stay close
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 a shirt.
To do 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.
