HOW A HEART RATE MONITOR WORKS
Your new LifeSource XC Heart Rate Monitor is a sophisticated athletic training tool that is
capable of measuring your heart rate with 99% accuracy. Top quality heart rate monitors use
a chest strap to pick up the electrical signal caused by the contractions of the heart and trans-
mit the information to the watch.
Every time the heart contracts, a short radio signal is sent from the chest transmitter to the
watch. The watch measures the time between the incoming signals, filters and averages
them and displays a heart rate number on the screen. The heart rate display on the screen
is updated every few seconds to assure you of an accurate measurement.
OPERATING TIPS
To achieve the most accurate heart rate reading possible, it is important to be aware of
circumstances that can cause false signals to enter the system and make your heart rate
measurement incorrect.
1. Your chest strap should be worn as tightly as possible without being uncomfortable. If the
chest strap is not tight enough, movement between it and your body can cause false
signals to be generated that may be seen as heart beats by the watch. This is especially
true during high impact activities such as running.
2. Environmental factors such as high-tension power lines, home security systems and radio
towers may interfere with the ability of the watch to receive a signal from the transmitter.
A loss of the heart rate signal and the heart rate display showing zero will usually indicate
this. This problem is transient in nature and will stop once you have passed out of the area
of interference.
3. Occasionally, if you are using your heart rate monitor in close proximity to other heart rate
monitors, it is possible for your watch unit to pick up the signal from the other transmitters
as well as yours. This is called cross-talk. When you are experiencing cross-talk, you will see
a very high heart rate or a heart rate of zero, if the combination of heart rates is greater
than 240 beats per minute. If this happens, simply allow a bit more space between you
and the other users.
4. Some clothing fabrics, especially in dry climates, are capable of generating a great deal
of static electricity. This static electricity is capable of significantly interfering with the sig-
nal from the transmitter. This shows up as erratic readings on the display. Over time you
should be able to tell what clothing, if any, you own which cause this problem.
Sometimes spraying the clothing before you workout with a commercially available anti-
static product will help reduce the problem.
5. If you are using your heart rate monitor indoors on an electrically powered piece of exer-
cise equipment it is possible that the power sources found in the equipment may inter-
fere with the heart rate signal in much the same way as in point 2. If you find that your
monitor is not working, try moving it to your other arm, or to another location on the
piece of equipment itself until you find an area where there is no interference.
6. Heart surgery or coronary events may cause changes to the function of the heart that will
make it difficult or impossible for your heart rate monitor to get a proper reading. Contact
your physician to determine whether you have a condition related to the above.
Being aware of these circumstances and knowing how to avoid them will significantly
increase your enjoyment of your new LifeSource Heart Rate Monitor.

GETTING STARTED
1. In dry and cold climates it may take a few minutes of use for the electrodes to soften and a layer
of perspiration to form between the contact and the skin for good performance. Moistening the
electrodes with saliva or conductive gel can speed up this process.
2. To ensure the most accurate operation we recommend wearing the chest transmitter against your
bare skin.
Users with a lot of chest hair may have a problem getting contact between the trans-
mitter electrode areas and their skin, resulting in poor performance. Because of this it may be
necessary for these individuals to shave the area of their chest beneath the transmitter.
3. Do not use water, moisturizing creams or suntan oil, as these are insulators and will
interfere with the heart rate signal.
4. Wear the wrist receiver as you would any
wrist watch. Keep the wrist receiver and the
transmitter within 3 feet/1 meter of each
other.
3. Adjust the strap so the transmitter fits tightly
below the pectoral muscles with the
LifeSource logo centered on the sternum as
shown in the picture.
2. Moisten the electrode areas —located to
the right and left on the back side of the
transmitter —with saliva or conductive gel.

SETTING AND OPERATING
PROGRAMMING THE XC100 & XC200
The programming of all functions of the XC100 and XC200 are accomplished in the same way.
The unit’s simple, one-button design makes programming easy with these three simple steps:
STEP 1: Enter a programming sequence by pressing and holding the key for 2 seconds. Once the screen changes
and you enter a sequence, release the key.
STEP 2: Adjust the display on the screen by pressing and releasing the key. The segment of the display being
adjusted will flash.
STEP 3: Once you have adjusted the display on the screen, set your choice by again pressing and holding the
key for 2-seconds. The screen will then advance to the next programming variable, or exit the programming
sequence.
SETTING THE CLOCK
1. From the Time of Day screen, enter the programming sequence by pressing and holding the key for 2 seconds.
2. Choose 12 or 24-hour format by pressing and releasing the key. Set and advance the display by pressing and
holding the key for 2 seconds.
3. Set hours, minutes (10’s) and minutes (1’s), and exit the clock programming sequence in the same manner.
SETTING AND OPERATING
SETTING THE HEALTH ZONE (XC200 ONLY)
The HEALTH ZONE functions are set from the Heart Rate screen. Your HEALTH ZONE is calculated using your
Maximum Heart Rate (MHR). The XC200 will estimate your MHR using your age and gender, or you can
set an actual MHR if you know it. Enter the HEALTH ZONE programming sequence by pressing and hold-
ing the key for 2 seconds.
A. Following the directions for programming listed on page10, begin by programming your age into the unit.
The unit will display “AGE” on the screen for a few seconds, and then advance to the number 10 with the
first (10’s) digit flashing. First program the 10’s digits of your age, followed by the 1’s.
B. Next choose either Male “M” or Female “F” and enter your choice.
C. The next screen will show your Maximum Heart Rate “MHR” for a few seconds, followed by the number that
the XC200 has estimated for your MHR.
D. If you wish to accept your estimated MHR, press and hold the key for 2 seconds.
E. If you know your actual MHR (from a stress test or other means), you can adjust the MHR setting to the
number that you desire, by 5’s. The XC200 will allow you to choose an actual MHR by cycling through a
range of ± 30 beats of your estimated MHR.
SETTING ABSOLUTE HEART RATE (AHR)
F. The last heart rate programming screen is Absolute Heart Rate (AHR). This number will usually be used if you
are under the care of a physician for cardiac rehabilitation. The first programming screen for AHR shows three
dashes “ --- --- --- “ indicating that the AHR function is inactive. To skip the AHR programming sequence,
simply press and hold the key for 2 seconds.
G. If you wish to program the AHR function, simply press the key until the number you want appears on the
screen, then set the number. Programming the AHR function will disable the Health Zone functions of the
XC200.
The Absolute Heart Rate Feature is designed for persons under the care of a cardiologist or in cardiac rehabilitation
therapy. It allows you to set a single heart rate number that is not to be exceeded during exercise. Once you have
programmed an Absolute Heart Rate number into the unit, exceeding that number will cause the display to flash and
the audible beeper tone to sound until you have reduced your heart rate.

SETTING AND OPERATING
OUT OF HEALTH ZONE AUDIBLE ALARM
The XC200 is equipped with an audible beeper alarm that lets you know when you are in your Health
(fat burning) Zone. This alarm is automatic, and cannot be turned off. If you are below your Health
(fat burning) Zone, the alarm will sound with a single beep. If you are above your Health (fat burning)
Zone, the alarm will sound a double beep. The alarm will sound approximately every 6 seconds.
CLEARING THE TIME IN HEALTH ZONE SCREEN
To clear the Time in Health Zone Screen, simply press and hold the key for 2 seconds when the watch
is in the Time in Health Zone Screen. Because the XC200’s Time In Health Zone screen will keep track
of up to 9 hours and 59 minutes of time, you can easily track the time that you spend in your Health
Zone for up to a week or more, if you wish.
SETTING AND OPERATING
HEALTH ZONE INDICATOR (XC200 ONLY)
At the bottom of the Heart Rate and Time in Health Zone screens is the Health Zone Indicator. The Health
Zone Indicator consists of a left and right arrow, and 4 small oval icons. Once you have programmed
the XC200, the Health Zone Indicator will light up as soon as the watch begins receiving a pulse. If you
are below 50% of your Maximum Heart Rate (MHR), the left arrow will light up, telling you that you
need to increase the intensity of your exercise. Once you are above 50% of your MHR and in your Health
Zone, the left arrow will go out and the first oval will light up. The 4 ovals represent 50-55%, 56-60%,
61-65% and 66-70% of your MHR respectively, and light up sequentially as you increase the intensity of
your effort. This makes it easy to tell where you are in your Health (fat burning) Zone. If you exceed
70% of your MHR, the four ovals and the right arrow will light up, telling you that you need to reduce
your exercise intensity to return to the Health (fat burning) Zone.

WARNINGS AND CAUTIONS
WARNING The LifeSource XC Heart Rate Monitors are training and fitness tools. Before begin-
ning any exercise program, consult your doctor for a complete physical and to discuss your
exercise plans.
CAUTION LifeSource XC Heart Rate Monitors are highly accurate and sophisticated technical
instruments. To ensure continued proper operation and to maintain a waterproof seal,
LifeSource recommends that only a jeweler or a qualified LifeSource technician replace the
battery in the watch unit. Improper replacement of the battery could damage the watch and
may void the manufacturers warranty.
CAUTION LifeSource XC Heart Rate Monitors are designed to be water resistant to 65 feet
(20m). This means that you should be able to shower and swim without water entering the
unit. However, to maintain water resistance you should be careful not to press any of the
buttons of the unit while it is wet or under water as this may allow water to enter the unit.
NOTICE TO ALL USERS High tension power lines, home security systems, automobiles, televi-
sions, microwave ovens, exercise equipment and other product cause various types of interfer-
ence that may temporarily affect the transmission of heart rate information from the chest strap
to the watch unit. These interferences are usually temporary and can generally be eliminated by
moving to an area away from the source of the interference.
NOTICE TO SWIMMERS Operating heart rate monitors while in the water may cause prob-
lems for a variety of reasons. First the chemicals in pools or the salinity of ocean water may
cause the chest strap to short circuit and be unable to detect a heartbeat. Second, water
resistance encountered while swimming will often cause the chest strap to move or pull away
from the skin making it difficult for the unit to detect a heart rate.
NOTICE TO PEOPLE WEARING PACEMAKERS While your heart rate monitor should
have no direct effect on your pacemaker, we strongly recommend you consult your physician
or cardiologist before using this product or embarking on an exercise program.
