Restrictions on use / guidelines governing use :

•

If you do not respect the following precautions, you risk losing the

Décathlon

guarantee.

•

Waterproof design: The stopwatch is classified as "water resistant". It can therefore be used

in humid conditions and is w

ater-resistant in rain or water spray. But it is not waterproof in

cases of immersion, nor is it designed to be used under water.

•

Care and maintenance : To preserve the Décathlon guarantee, any operation or repair must
be exclusively entrusted to a Décathlon electronics shop. If one is not available, no dysfunction
can be claimed in the context of the Decathlon guarantee, with the exception of hidden defects.

•

When changing the battery, replace the seal and check for water-tightness.

•

If condensation appears or water infiltrates, check the device immediately. Water may
attack the electronic elements inside the casing.

•

Avoid submitting the device to hard shocks like those received when falling onto a hard

surface.

•

Do not expose the stopwatch to extreme temperatures.

•

Clean only with a slightly damp, soft cloth, and do not use detergents or soap, which may
cause the materials to deteriorate.

•

Keep the device away from any strong electrical field or area of static electricity.

Operating problems:

If you encounter a problem with the read-out please check the batteries first.

Recycling:

The ‘crossed out dustbin’ sign means that this product and its batteries cannot
be thrown out with domestic waste. They should be treated apar t. When you
have finished with them, drop them at an authorised collection point so they
can be recycled. This gesture will go towards protecting the environment and
your health.

First use

The setting of the time

, the date

, the

TIMER and the PACER are explained in the sections

dedicated to the different modes

Initialization : In case of problems with the display or a significant dysfunction,

press the 4 buttons simultaneously (START/STOP, MODE, RECALL, SPLIT/RESET)
to reinitialize the stopwatch (RESET).

batteries : The stopwatch uses a CR2032 type battery

Replacing the battery is done by unscrewing the back cover a quarter turn, using a coin,
for example.

Inserting the battery is done according to the following diagram. Make sure the polarities
are correctly placed. Remember to protect the environment and dispose of your batteries
or y

•

Use

Using the RECALL button (brief press), scroll through the different countdowns until you
come to the one that indicates the interval of time for the first block (in our case T1).
This step enables you to check that the device is correctly programmed.
The START/STOP button starts or stops the session
The countdowns are strung together in numerical order (T1-T2-T3…) until a countdown
programmed at a null value, then begins again with T1.The repetition counter counts up.
If the first countdown is not T1, the repetition counter increases by 1 just before beginning
again with the countdown from the beginning (ex: 3 countdowns, T1, T2, T3 have been
programmed. The first of the session is T3. The counter is therefore increased after having
completed T3, then T1, then T2, and just before beginning T3 again).

•

Buzzers :

To differentiate auditorily between the types of buzzing for countdowns and for the
progression of the session, the final beeps have been differentiated:
End of a countdown: 3 beeps in close succession.
End of a repetition: 2*3 beeps in close succession
End of the session: 4*3 beeps in close succession

- Bottom line : SPLIT, the intermediate time

•

In this mode, the screen will display the letters STW in the middle of the screen when

the stopw

atch is functioning. When the stopwatch is stopped, the word STOP will appear

on the left of the screen.

•

The stopwatch enables you to measure intermediate times (SPLIT, the time passed

since the start up to the given point) and laps (LAP, the time passed since the last
partial time measurement up to the given point).
It enables you to measure up to 999 intermediate times and to store the first 299
measurements in memory.

•

On the top line, you will read the current stopwatch value (Format - hour :minutes : seconds

: 1/100s).The maximum value is 99 h 59min 59s 99

•

On the middle line

, you will read the lap time value

(LAP) (F

ormat - hour : minutes :
seconds, hundredths of seconds).
On the top left of the screen, the three-digit indication of the intermediate time counter will
appear.

•

On the bottom line you will read the value for the intermediate times (SPLIT).

•

To re-initialize the stopwatch

When the stopwatch has stopped, press the SPLIT/RESET button for 3s to reset to 0.

The stopwatch is started/stopped by pressing the START/STOP button. You can accumulate
several time measurements by pressing

START/STOP again between each measurement.

When the stopwatch is going, by pressing repeatedly on the SPLIT/LAP button, you can
display intermediate times and lap times on the corresponding lines. With each press, the
intermediate time counter goes up by one.

Once the number 299 is reached, the counter will flash to signal that the memory is full.
Display of the word

FULL

When the stopwatch has stopped (START/STOP), the last lap is put into memory.

•

Using the memory.

When using the stopwatch, the first 299 intermediate times and lap times are memorized.
They can be recalled, whether the stopwatch is in action or not, by pressing the RECALL
button. The order of reading is different depending on whether the stopwatch is
functioning or not.
