2/ Use / Precautions for use

This heart rate monitor is made up of a watch and a chest strap. The watch is designed to be worn on the
wrist or placed on a bicycle holder during various sporting, physical activities in a temperate climate. The
chest strap has a 32 channel coded transmitter. You must be inside the reception area (diagram 2).

User limitations / precautions for use:

All precautions for use and restrictions are listed page 3 of these instructions.

WARNING!!!

This equipment is designed for sports and leisure use. It is not a medical monitoring device. The information
provided by this equipment or manual are only used by way of example and must only be used to monitor a
medical disorder after consulting and obtaining agreement from your doctor.

Similarly, athletes in good health must take into account the fact that determining your maximum heart rate
and personal training zones are vital elements in designing an effective and risk-free training programme.

We recommend that you seek advice from your doctor or health adviser to set your maximum heart rate,
your upper and lower heart rate limits and the frequency and duration of exercise suitable for your age,
physical condition and desired results.

Finally, as a result of possible disturbance caused by the radio transmission system, we do not recommend
that users of heart stimulators use a heart rate monitor which uses this form of technology.

Not observing these precautions may put your life at risk.

3 / The chest strap

Fitting the chest strap

The installation process for the strap is explained at the start of these instructions (diagram 1). The chest
strap serves as a sensor and transmitter. It measures the differences of potential created by the heartbeat
on the surface of the skin. It transmits this information
to the watch by radio signal. The quality and accuracy
of its measurements and comfort during use depend on
it being correctly positioned. As shown in the diagram,
the sensors are black rubber surfaces either side of the
central part.

When correctly placed, the strap sends heart rate information to the watch. Located in the reception cone
(diagram 2), the watch displays the heart rate and other information (target zone, exercise intensity... ) to

optimise your tness and training.

Avoid positioning the sensors in overly hairy areas. In cold and dry climates,
the strap may need several minutes to work properly. This is perfectly normal

as the sensors need a lm of sweat to ensure contact with the skin. When

measurements start, the watch may indicate very high values for around 20
seconds. This is due to the initialisation of the algorithm. It will display correct
values following initialisation. Take care when inserting the elastic strap binding

into the hole designed to house the strap. Hold the pin while passing your nger

behind the strap.

5.1/ Using cardio mode and main information

The main information in this mode is the heart rate.

IMPORTANT:

• To get heart rate information, you must be wearing the strap. (Don’t forget to moisten it rst.) If it is correctly
tted it will automatically emit the heart rate signal. For more information on tting the strap, see diagram

1 or paragraph 3.
