Specifications

• Waterproof construction of watch: 5ATM
• Waterproof construction of chest belt: 1ATM (not suitable for swimming)
• Temperature: from –10°C (14°F) to +50°C (122°F)
• Radio transmission: amplitude modulation on carrier wave of 5 kHz
• Stopwatch from 0 to 99h59m59.99s:resolution 1/100 s
• Exercise stopwatch from 0 to 99h59m59.99s : resolution 1 s

Batteries:

- Watch: CR 2032 (not to be changed by the user)
- Chest belt: CR 2032
- Approximate service life of the batteries with normal use (5 hours of use per week
in heart rate monitor mode):1.5 years for the watch and approximately 1 year for
the chest belt.

Important:

The backlight feature consumes a great deal of energy (2,000

times more than the normal operation of the watch). If this function is used fre-
quently, the service life of the batteries may be very greatly reduced and the batte-
ries have to be changed after a few hours of use.

TRAINING GUIDELINES

For reasons of effectiveness and safety, you must know certain physiological para-
meters required for training. The advice that we provide here is intended for healthy,
active persons who do not present any pathologies. We strongly advise you to obtain
the advice of your physician in order to establish your training zones accurately.

obtain the advice of your physician in order to establish your training zones accura-
tely.

Important: 

Know your limits and don't go over 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 fitness program, several training zones will give specific results corres-
ponding to different objectives. Depending on the intensity of exertion, the percen-
tage of the energy coming from the combustion of sugar and that coming from the
combustion of fats varies.

E.g. A 30-year-old athlete who is training for aerobic endurance in order to increase
his stamina and improve his time in the 10,000-meter run. The most effective trai-
ning zone for his objective will be 80% to 90% of his maximum heart rate.
