WEARING THE HEART RATE TRANSMITTER STRAP
(PULSEWARE DUO ONLY)
The heart rate transmitter strap consists of two conductive electrodes
attached to a small radio transmitter housed in the center of the
strap. The electrodes sense the electrical potential created each
time your heart contracts and the radio transmitter sends a signal
to the watch each time the electrodes sense the heart beat. For
the best performance, a layer of sweat should be built up between
your skin and the electrodes of the transmitter. This makes it easier
for the electrodes to “see” the electrical signal. On cool days or at
the beginning of your workout it may be necessary to moisten the
electrodes on the back of the transmitter using saliva or one of the
commercially available electro conductive creams. DO NOT use tap
water to moisten the electrodes as tap water will act as an insulator
rather than a conductor and may actually reduce the performance of
the system
The transmitter should be worn around the rib cage, just below the
pectoral muscles. The elastic strap of the system should be adjusted
so that it is snug enough so it does not move during use, but not so
tight as to restrict breathing. While the wearing of the transmitter
strap may feel a bit strange initially, most people become used to it
within a few days and cease to even notice they are wearing it.
INTERFERENCE
For reasons of size, cost and battery life, heart rate monitors function
using a very low transmission frequency. Because of this they are
susceptible to interference from a variety of electromagnetic and
microwave sources. High-tension power lines, traffic light controls,
home and automotive electronics, powered exercise equipment; home
security and wireless LAN systems and other things may interfere
with the ability of the system to register a heart rate. Intermittent
readings of zero or of very high heart rates (exceeding 210 beats)
are an indication of some type of interference. In general, the
interference caused by these sources is localized. After a few seconds
or at most minutes, you should pass from the area of interference and
the operation of the watch should return to normal. Additionally, other
heart monitors close by may also interfere with the function of your
unit. It is recommended that you separate yourself from other heart
rate users by a minimum of 3 feet (1 meter) in all directions.
