This depends on the legal warranty conditions.

To activate the chest belt, regardless of the model, the electrodes must be moist. If these are NOT moist, a seamless heart rate measurement cannot be guaranteed.

If an inaccurate heart rate reading is often displayed at the start of a training session, this can be due to the chest belt being too dry. If you experience this problem regularly, also moisten the chest belt at the points that are directly beneath the contact surfaces of the chest belt. This will provide moisture for the first few minutes until you start to sweat. The heart rate measurement should now work properly again.

Care instructions for the standard chest belt:

After every training session, wash the belt and the transmitter with clean water and hang them up to dry.

Regularly clean the transmitter with a mild soap solution.

Wash the belt regularly (every 3 – 4 weeks) using your washing machine’s hand wash program. For washing, only use mild detergent and a wash bag.

Care instructions for textile chest belts such as COMFORTEX/COMFORTEX+:

Remove the transmitter from your COMFORTEX/COMFORTEX+ chest belt after every training session. Wash the COMFORTEX/COMFORTEX+ belt with clean water and hang it up to dry.

Wash the COMFORTEX/COMFORTEX+ chest belt regularly (every 3 – 4 weeks) using your washing machine’s hand wash program. For washing, only use mild detergent and a wash bag.

Please note that you should never put your COMFORTEX/COMFORTEX+ in a dryer or allow it to dry in direct sunlight. It should also not be bleached or ironed.

Never clean your COMFORTEX/COMFORTEX+ chest belt with aggressive detergents or chemicals.

You can change the battery yourself in all SIGMA heart rate monitors and running computers with a battery compartment. The battery type name can be found on the battery cover.

For heart rate monitors and running computers without a battery compartment, we recommend having a specialist sports retailer or watchmaker change the battery.

You can also wear your SIGMA heart rate monitor and running computer when swimming. However, please note that this is not a diving instrument and you must not press any buttons whilst underwater as the water resistance can then not be guaranteed.

Water resistance

The water resistance is tested in the watch industry in line with the international standard ISO 2281. This states that the water resistance is marked with the level of the water column which corresponds to a static water pressure in a certain depth of water. This is a theoretical value as a dynamic pressure is always exerted in water. This depends on the movement in the water and the movement of the water itself. The dynamic water pressure, at a particular depth, is far higher than the static water pressure. It is therefore only possible to use products given a water resistance of at least 3 ATM for swimming.

You are furthermore unable to access the heart rate measurement underwater as the water prevents signal transmission from the chest strap to the device.

You can store up to seven training sessions with up to 99 laps.

When you finish your training, this is automatically stored in the memory.

You can then use the memory to access the last seven training sessions and all the laps.

If you want to view your completed laps while still training, you can do so using the EasyLap View function.

The upper or lower operating temperature limits may have been breached.

Your sport computer is designed for temperatures from 1°C to 55°C.

A weak display can be caused by a weak battery.

The battery should be changed as quickly as possible – battery type CR 2032 (ref. no. 00342).

No as the elasticated belt is infinitely adjustable.

No. In standby mode, only the time, date and heart rate monitor are displayed so that you can also use the heart rate monitor as a normal watch. In this mode, the heart rate monitor uses very little power.

Yes, the signals can be received and displayed by almost all appropriate cardio equipment.

In some cases. We strongly recommend consulting a doctor before use.

Yes. The pulse computers are not encoded and all transmit at the same frequency.

As soon as they are 1.5 m apart they no longer interfere with one another.

You can also use your heart rate monitor without a chest strap. As long as the stopwatch is running, the time is displayed instead of the pulse. If the stopwatch is stopped, your heart rate monitor will return to sleep mode after 20 seconds.

You can make a warranty claim in relation to material and workmanship defects. The warranty does not cover batteries, wear-and-tear parts, wear caused by commercial usage, or accidents.You are only entitled to make a warranty claim if the SIGMA product itself has not been opened without authorization and the receipt of purchase is provided.

Accessories are available in the SIGMA Webshop.

Warranty claims can be made in the event of material and workmanship errors. Excluded from the warranty are batteries, elastic straps, textile chest straps, e.g. Comfortex, wear and tear parts and wear due to commercial use or accidents. If no speed is displayed, this can be due to the transmitter or the computer.
