Use • Precautions for use
Normal conditions of use:
This watch is designed to be worn on your wrist for mountain sports
(hiking, mountain-biking, etc) It is for telling the time and measuring
lap times, using the stopwatch function. It features several
measurement instruments (barometer, altimeter, compass) to orient
yourself and describe outdoor environmental conditions.
Usage restrictions/recommendations for use:
• Waterproof design: This watch is waterproof to 5 ATM. It can therefore be
used in damp conditions, in heavy rain, in the shower, and for swimming.
However, do not wear the watch while diving or at a depth greater than 5
metres. However, you should not swim while wearing it. Do not press the
buttons under water.
• Handle the device with care: do not drop it and do not subject it to
significant impacts.
• Do not dismantle the watch. This would void the warranty and could
cause damage and loss of waterproofing.
• Read the instructions carefully before using it. Keep the instructions for
the entire life of the watch.
• Do not subject the watch to extreme temperatures. If the watch is
exposed to direct sunlight for long periods of time, the display may
darken temporarily, but will go back to normal once it has cooled down
again.
• Only clean with a soft, damp cloth. Do not use detergents, which risk
damaging the watch equipment.
I WARNING: Altitude calculations are based on variations in
pressure. We also advise you to set the value of the “sea level
pressure” parameter every time there is a significant change in the
weather or altitude (aeroplane) and the first time you use the watch in
order to avoid calculation errors. Indeed, air pressure varies not only
according to altitude but also because of the weather. To set “sea
level pressure” contact a meteorological centre or get the information
from an official website and see the adjustment section of these
instructions. Important This watch has an accuracy tolerance of +/- 8m
in altimeter function.

First use
Batteries: This watch uses a CR2032 battery. Please note: if you note
that the display is flashing unusually or doesn’t appear to be working
correctly, this usually means that the watch battery is low and needs
to be replaced. We recommend that you take the watch to a
DECATHLON specialist to have the battery replaced. If you change
the battery yourself, you risk damaging the seal, thus impairing the
waterproof design as well as voiding your warranty. Please check the
availability of the battery with your dealer before travelling. The
approximate battery life is one year, but this can vary depending on
how long it was stored in the shop and the way in which the watch is
used. The raw materials and the battery contained in this device can
be recycled by a professional. In order to protect the environment, we
encourage you to dispose of this product and/or the batteries which it
contains after using them in a collection site designed for this purpose.

Using the time mode
This mode provides information relating to the time and date, and
optionally displays weather conditions and the temperature.
The watch can display two time zones (indicated by T1 and T2)
• You can quickly see the time zone which is not displayed by
pressing B
• You can choose to display either time zone permanently by holding
down B (T1 or T2 flashes while you press the button and is then
displayed continually).
NB : The two time zones, T1 and T2, are independent:
hour, minutes, date. Only the seconds are identical in the two zones.
T1 and T2 must therefore be set separately.
The calendar automatically calculates the day of the week for all dates
from 2000 to 2049.
There are three time display modes:
• Time/date (TIME)
• Barometer time (BAROMETER)
• Time/weather forecast (WEATHER)
You change between modes by pressing A or E as in the following
diagram:
NB : The graphic display of sea level pressure and barometric trends
are described in the barometer chapter.

The value displayed in the table includes the corrected declination. This is
the correction between the geographic North pole and the magnetic North
pole.
I WARNING: it is very important to hold the screen horizontally so that
the calculated measurements are reliable. Otherwise the measurements
will not be correct. Like all compasses, this watch is sensitive to magnetic
fields. It is designed to be used outdoors, away from any metal parts and
magnetic sources (pay particular attention to watches, keys, table legs,
electric cables, computers, mobile telephones) which would cause
incorrect measurements. Also, before any significant use of the compass,
do not forget to calibrate it.
IWARNING: the compass function uses a lot of energy.
To save the battery, it will only be activated for around ten seconds before
the display turns off (- - -).
However, you can reactivate measurement by pressing button A again.
You can also hold down A for as long as you like.
In this case, the direction will be displayed for as long as you press the
button.

Weather conditions display:
The watch displays symbols to give an idea of the local
meteorological trends over the coming hours. The calculation is based
on barometric measurements, and the display is the same as in time
mode.
There are four trend symbols:
I WARNING!
Weather forecasting is not an exact science!
No professional institute in the world is capable of 100% certainty.
The forecasts given by the watch should be taken as an indication.
If you have to make an important or dangerous excursion (sea,
mountains), confirm the MW500 predictions by contacting your local
meteorological institute.
Furthermore, at sea and in the mountains, climatic conditions can
change extremely rapidly, creating life-threatening conditions.
Be prepared and extremely careful.
IWARNING:
The meteorological predictions will only be reliable if the barometer
has been functioning correctly for at least the last 12 hours. (for
example, if there have been no significant changes of altitude or
aeroplane journeys).
Barometric pressure display:
On the top line:
Sea level pressure over the last 24 hours. The latest value is on the
right. Each point represents one hour. It is impossible to read the
exact values on the graph. Only the trend can be read from the graph.

On the middle line:
The pressure displayed in the large digits on the middle line is the sea
level pressure in current conditions. This system ensures a continuity of
trends, even if your altitude has varied.
On the bottom line:
Three displays are possible.
Press Aor Eto go from one to the next according to the following
model:
NB : The barometer varies by intervals of 1mbar and displays
pressures from 300mbar to 1100mbar.
To change the barometric pressure units, hold down B until the unit of pres-
sure (mbar or mmHg) stops flashing to change from mbar to mmHg and
vice versa.
Temperature display:
IWARNING: Body temperature may influence the value
displayed. For an accurate idea of the outside temperature, take the
watch off your wrist and place it on a surface at ambient temperature.
Allow the watch to adjust to the ambient temperature (three to five
minutes) and the display will stabilise.
NB : The temperature varies by intervals of 0.1°C and variations are
recorded very precisely. However, the accuracy of the absolute figure is
lower (1 to 2°C). Comparing the display with another thermometer may
lead to errors, as the value depends on the calibration of the two devices.
To change the units of temperature measurement (°C <> °F).
You must be in “BAROMETER” mode.
Keep pressing A or E to
display the temperature on the bottom line.
Hold down B until the unit of temperature (°C or °F) stops flashing to
go from °C to °F or vice versa.

Calibrating measurements.
The watch measures altitude and atmospheric pressure using the same
sensor. It cannot therefore determine whether the atmospheric pressure
changes because of a change in altitude or changed climatic conditions.
You therefore need to calibrate the barometer to the altitude of the mea-
surement site.
Calibrating sea level atmospheric pressure.
Hold down D until the words “SET CURRENT WEATHER” scroll
across the screen. The weather symbol starts to flash. Press C: “SET
SEA LEVEL PRESSURE” scrolls across the screen.
Sea level pressure begins to flash. Press A (+) and B (-) to increase
or decrease the displayed value, according to the information in an
official meteorological report for example. Press D to exit adjustment
mode.

4 - Altimeter Mode
A : display cumulative altitude difference and max
altitude/waypoint storage
B : adjust the unit
C : go to Alti data mode
D : electroluminescence
E : inactive
In this mode the watch measures and displays local altitude in relation to
sea level. This mode can also graphically display recent variations in
altitude.
NB : altitude is displayed in metres (m) or feet.
The accuracy of the sensor allows for measurements at intervals of 1m (or
1 foot) and in a range from -700m (-2296 feet) to +9000m (29520 feet).
IWARNING: altitude is calculated on the basis of atmospheric
pressure measurements. If changes in the weather cause variations in
pressure, altitude will be measured incorrectly as a result, and it is
therefore necessary to calibrate it very frequently when the weather is
changeable. Similarly, the accuracy of altitude measurements is indicative.
Even though the pressure sensor is very accurate, climatic factors, even if
imperceptible, affect the accuracy of the value (1mbar pressure difference

perspective yourself.
Altitude display
On the top line:
Graph of variations in altitude over the last six hours. One dash
corresponds to a time period of 15 minutes. The range of the graph is
calculated according to the variations in maximum altitude. You cannot
therefore read the altitude value from the graph.
On the middle line:
In the middle, the altitude at the measurement site is displayed. The
unit of measurement (m or ft) is indicated at the bottom right of the
figure.
On the bottom line:
Local time display.
To change the units of altitude measurement (m/ft) Hold
down Buntil the unit symbol (m or ft) stops flashing to set the display to
the corresponding unit.
Display maximum altitude and positive altitude difference
The watch stores the maximum altitude and the positive altitude
difference measured throughout the time spent in Altimeter mode.
IWARNING: these values are not updated when the watch is in a
mode other than “altimeter” mode.
IWARNING: the watch does not calculate negative altitude difference.
•Calculating positive altitude difference: the watch takes the sum of
all positive vertical movements (climbs) made during the
measurement period. E.g. if a hiker climbs 10 metres, descends 5
metres and then climbs a further 10 metres, the positive altitude
difference is 20m.
IWARNING: The calculation of cumulative altitude difference is a
mathematical one. If the display oscillates between two values, the
cumulative value will increase every time it oscillates between the
lowest and the highest value. The cumulative value will therefore be
more accurate when climbing regularly than when travelling at an
altitude which is more or less constant.

•Measuring maximum altitude: the watch displays the maximum
altitude reached by the user since the device was last started. The
positive altitude difference and maximum altitude are displayed when
entering altitude mode. The values scroll across the top line: ACC xxx
MAX xxx. To display the values while using altimeter mode: Press A
to display the positive altitude difference and maximum altitude.
Calibrating measurements.
The watch measures altitude and atmospheric pressure using the same
sensor. It cannot therefore determine whether the atmospheric pressure
changes because of a change in altitude or changed climatic conditions.
You therefore need to calibrate the altimeter every time weather
conditions change.
Calibrating local altitude.
Carry out this operation based on a point at a known altitude
(refuge, boundary marker, mountain summit or pass). Hold down D
until the altitude in the middle of the screen begins to flash.
Press A (+) or B (-) to
increase or decrease the displayed value to reach the known
altitude. Hold down A or B to scroll through the values more quickly.
Press C to start the positive altitude difference count.
Press A or B to reset the altitude difference counter to zero.
Press C to start the maximum altitude count.
Press A or B to reset maximum altitude to zero.
Press D to exit adjustment mode.
If no button is pressed for 2-3 minutes, the display automatically
returns to normal.
Memorising altitude and waypoints.
The watch can store the altitudes of landmark waypoints: cottages, passes,
summits, valleys and villages. The date and time of arrival will also be stored.
RECALL mode, described in the following chapter, will recall these points.
To store a waypoint:
Hold down A until the word “DATA” stops flashing to store the altitude
of the waypoint in the memory. The word “STORED” is then displayed
as confirmation.
