Precautions

Normal conditions of use:

This heart rate monitor consists of a watch and

a pectoral belt. The watch is designed to be worn on the wrist or on its bicycle support
during the practice of various light sports in a temperate climate. It indicates time and
date and measures intervals of time manually with its stopwatch function. The pecto-
ral belt must be placed on the chest. If it is positioned correctly, it transmits information
on your heart rate to the watch. If placed in the reception cone, the watch then dis-
plays your heart rate and sounds an alarm if you exceed the "target zone" that you
are able to program yourself.
The purpose of this information is the planning and optimization of your shape-up
program or training.

Restrictions on use / guidelines governing use

•

Waterproof design: The watch is waterproof to 5 atmospheres. It can therefore be

use in humid conditions, in heavy rain, in the shower and for swimming. However,
avoid diving and wearing the watch at a depth of below 5 meters. Do not operate the
buttons underwater.

•

The chest belt is only "water resistant". It is therefore impermeable to sweat and

can be used in rain or under damp clothing. It must not be worn in the shower or
when swimming, however.

•

Treat the watch with care; do not drop it or bang it.

•

Do not dismantle the watch. This will render the guarantee invalid and could cause

damage and loss of waterproofing.

•

Please read guidelines carefully before use. Retain these guidelines for as long as

you have the watch.

•

Do not operate the buttons under water and do not go beyond the depth indi-

cated in the following table with the watch.

•

Do not subject the watch to extremes of temperature. If the watch is subjected to

direct sunlight for a long period, the display may darken temporarily, but will go back
to normal once the temperature has dropped again.

•

Do not operate the buttons under water and do not go beyond the depth indi-

cated in the following table with the watch.

•

Do not subject the watch to extremes of temperature. If the watch is subjected

to direct sunlight for a long period, the display may darken temporarily, but will go
back to normal once the temperature has dropped again.

•

Clean the watch and the belt with a soft, damp cloth only. Do not use detergents

since they may damage the materials of your watch. Only the elastic of the belt may
be machine washed (30°).

CAUTION!!!

This device is designed for use in sports and leisure activities. This is not a medi-
cal monitoring device. The information provided by this device or this booklet are
for information only and must not be used for monitoring a pathology except after
consultation with and the agreement of your physician.
Even athletes in good health must take into account that the determination of
your maximum heart rate and your personal training zone is a vital element in the
scheduling of effective, risk-free training. The advice of your physician or health
professional is recommended for determining your maximum heart rate, your
upper and lower cardiac limits and the frequency and duration of exercise
adjusted for your age, physical condition and targeted results.
Finally, because of possible disturbances generated by the radio transmission
system, we do not recommend that persons who wear pacemakers use a heart
rate monitor utilizing this technology, like the CW.
Not taking these precautions may entail serious risk.

Wearing the chest belt.

The chest belt acts as a sensor
and emitter. It measures
the differences in potential
created on the surface
of the skin by the beating of
your heart. Then it sends this
information to the watch by radio signal.
The quality and precision of the measurements depends on correct positioning, but
also the comfort during practice.
As indicated in drawing 1, the sensors are the surfaces of black rubber on both
sides of the central part.

Installation procedure:

Wet the sensors with water or a water-based conducting gel
to ensure good contact

Introduce one rib of the elastic into one of the holes on the belt
provided for this purpose.

Attach the belt around the chest, then position
the belt just below the pectoral muscles with
one of the sensors under the heart and
the other under the right pectoral.

Adjust the length of the elastic so that
it holds firmly but is still comfortable.
The belt must not move around if you jump
or move your arms.

Check the positioning of the belt

by bringing it to 50 cm from the watch.
The heart rate should flash on the
display. If it does not flash normally:

- reduce the distance between the belt

and watch

- adjust the position of the belt and

wet the sensors well

- check that the batteries are good,

especially in the belt

- go to cardio mode (see paragraphs 6 and 7 for procedure)

and press S1 to test the connection

ATTENTION :

Avoid positioning the sensors in areas that are too hairy.
In cold and dry climates, the belt may need several minutes to function correctly.
This is normal because sensors need a film of sweat to ensure contact with
the skin.
When it first begins measuring, the watch may indicate very elevated values
for about for about 20 seconds. This is because the algorithm is initializing.
The display will stabilize at correct values after this interval of time.
Take precautions when fixing the elastic strap in the hole of the belt provided for this
purpose. Maintain the ergot by placing your finger behind the belt

Navigation system

Using the heart rate monitor:

See paragraph “Wearing the chest belt” for positioning the belt.
Once everything is installed, bring the watch to within less than 50 cm of the belt
and then press S1 to test the connection.
-> The heart on the display begins to flash and a value is displayed.

ATTENTION :

Disregard the values indicated before the device stabilizes (about 20 seconds).
This is the time necessary for the calculation algorithm to provide smooth, reliable
numbers.

ATTENTION :

The pectoral belt does not have an encoded emitter; interference is to be
expected if you are located too close (about 1 meter) to other heart monitor
wearers.
If the radio connection between the watch and the belt is interrupted for more than
1 minute, " ---" will be displayed on the middle line. To reactivate the connection,
press S1.

Setting the target zone:

In cardio mode (PULS), press S2 for more than 3 seconds (the word HOLD is dis-
played and then disappears) to return to the settings mode for the target zone.
The upper limit of the target zone is displayed and flashes with the indication "HI"
at the bottom of the screen.
Set this upper limit by pressing S1 (scroll rapidly by holding S1 down)
Press S3 successively to change the parameters to be set, in accordance with the
following drawing:

Then press S1 to set the different values of the parameters.
When you have finished with all the settings, press S2 to exit the settings mode.
In the "cardio" function, if the heart rate displayed is higher than the upper limit of
the target zone, the display indicates this with the following symbol (fig a.).
If it is lower than the lower limit, the symbol displayed is the one in figure b.
If the passing alarm is activated (ON), the watch emits 1 beep every 6 seconds if
the heart rate is LOWER than the target zone.
The watch emits 2 beeps every 6 seconds if the heart rate is HIGHER than the tar-
get zone.

Watch:

We recommend that you not change the watch batteries yourself, but rather

have the job done by a specialized DECATHLON repair shop. If you change the battery
yourself, you may damage the seal and lose both the water tightness and guarantee on
the product.
Please check the availability of the battery with your dealer before replacing it.

Pectoral belt:

If the heart rate indications become inconsistent, or if the heart

monitor light on the watch does not flash when it is close to the belt, it may be
necessary to change the battery in the chest belt. You can easily change the belt
battery yourself, without the aid of any particular tool.

Changing procedure:

Unscrew with the aid of a coin, then remove the cover of the battery compartment

Remove the old battery by tapping on the opposite side of the belt

Replace the used battery with a lithium 3V type CR2032 battery without touching it
on its 2 terminals (it may discharge), with the +terminal (printed surface) up

Carefully replace the cover, then screw it down again by a quarter turn to the
"closed" position

If there is a problem, contact your retailer..

If you do not find a solution to your problem in this troubleshooting table,
please contact DECATHLON after-sales service.

Notice CW:NOTICE CW 28/03/07 11:11 Page 22

Operation / Procedure

Moisten the electrodes using conducting aqueous gel or water.

Check the positioning of the belt around your chest: it should be positioned as
shown in the instruction leaflet.

Bring the HRM watch and the belt closer together, check the above points, and
then check transmission. If there is no transmission, change the belt battery as
shown in the instruction leaflet.

Please visit a DECATHLON workshop to have your HRM battery changed.

You may be in an area with a strong magnet field, a high voltage power line,
radio communication equipment, etc.
If this is the case, move away from this area.

The belt does not have a coded transmitter. You will receive interference when
less than 1 metre from other HRM users.

Check that the belt is tightened and that the electrodes are moistened. Rubbing
of the belt sends a signal different to that of a heart rate.

During cold and dry weather, the product may give incorrect information for a
few minutes. This is normal, as a film of perspiration is necessary for good
contact between the electrodes and your skin.

For around ten seconds, the displayed value may be inconsistent with your real
heart rate. This is because the algorithm is initialising.

Hold down buttons S1, S2, S3 and S4 together for 1 second to RESET the device.
Now set the device as shown in the instruction leaflet.

The target zone alarm is probably active and you are outside of the zone.
See the instruction leaflet for details of how to set or deactivate the target
zone alarm.

Principles of training

For reasons of effectiveness and safety, it is indispensable for you to know certain
physiological parameters required for training. The advice that we provide here is
intended for healthy, active persons who do not present any pathology. We stron-
gly advise you to obtain the advice of your physician in order to establish your most
precise training zone.

ATTENTION :

Know your limits and do not exceed them !!

To optimize the benefits of your physical preparation, you must first know your
maximum heart rate (FCmax) expressed in beats per minute (bpm)
The FCmax can be estimated by the following formula:
FCmax=220-your age

During a shape-up program, several training zones will give specific results corres-
ponding to different objectives.
Depending on the intensity of the exercise, the percentage of the energy coming
from the combustion of sugar and that coming from the combustion of fats changes

Ex: A 40-year-old athlete who is training in order to maintain her figure and control
her weight. She must optimize the part of her energy coming from the burning of fat.
Her chosen training zone is 60-70% of her FCmax.

The lower and upper limits of the target zone are calculated by multiplying your
FCmax by the limit percentages of the selected training zone.
This equation also measures your resting heart rate (FC rest), which you can sim-
ply measure with your heart rate monitor early in the morning when you wake up.

Limit of the target zone = FC rest+ intensity % *(FC max –FC rest)
FC max=220-40=180 bpm
FC rest = 60bpm
The upper limit of the target zone is
FC rest + 70%*(Fcmax-FC rest) = 60 + 70%*(180-60) =144 bpm
The lower limit of the target zone is
FC rest + 60%*(Fcmax-FC rest) = 60 + 60%*(180-60) =132 bpm
