Frequently Asked Questions - TRIAX C3 NIKE

How to properly wear the heart rate transmitter?

Place the transmitter around your chest, on the ribs just below the sternum. It should be in direct contact with the skin and tight enough not to slip during running. Generously wet the two grooved areas on the back of the transmitter to ensure good signal reception.

What to do if the watch does not display heart rate?

Check that the grooved sensors are sufficiently wet and that the transmitter is positioned correctly, flat against the skin. If the problem persists, replace the transmitter battery. Move away from sources of electromagnetic fields (household appliances, computers, power lines).

The displayed heart rate is irregular or stops, what to do?

This may be due to a low battery in the transmitter or electromagnetic interference. Replace the transmitter battery and change location. Also check that the transmitter is in good contact with the skin and that the electrodes are wet.

How to reset the watch if the display is frozen?

If the display freezes (e.g., after a static discharge or battery replacement), press and hold both buttons simultaneously. This clears the data in memory and restores factory settings.

Is the watch waterproof? Can I swim with it?

The watch is water-resistant up to 30 meters (IPX8) and can be used underwater. Caution: do not press the buttons underwater, as this could damage the watch.

What battery does the watch use and how to change it?

The watch uses a CR2032 3V Lithium battery. Replacement must be done by an authorized Nike service center to keep the warranty. The transmitter also uses a CR2032 battery; open the cover with a coin, insert the battery with the positive side visible without touching the contacts.

Can I use this watch if I have a pacemaker?

Consult your doctor before using the heart rate monitor. It is not recommended for wearers of pacemakers or other electronic implants without prior medical advice.

How to clean and maintain the transmitter?

Wipe the transmitter after each use. Do not store it near conductive materials. Avoid bending it or exposing it to extreme temperatures.

What is the accuracy of the heart rate measurement?

The accuracy is ±1% or ±1 bpm (whichever is greater) in steady state. For optimal measurement, wear the transmitter directly on the skin and wet the electrodes.

Where can I find the full manual?

The user manual is available for free download in PDF format on notice-facile.com or on the site www.nike.com/manuals.

Heart Rate Transmitter

Your Heart Rate Transmitter reads the electrical impulses of your heart and transmits data to your watch. It is one of the most accurate ways to measure heart rate. The Transmitter will function automatically if it is worn correctly within a meter of the watch. The Transmitter is ergonomically designed to fit comfortably during all types of exercise.

ATTENTION: Anyone beginning an exercise regimen for the first time (especially users of pacemakers or other implanted devices) should consult their physician or health professional before using the heart rate monitor.

Troubleshooting

No heart rate displayed on watch:

The grooved sensors may not be wet enough. Wet and try again. It is recommended that you wear the Heart Rate Transmitter directly against your skin. If you are wearing the HR Transmitter over clothing, try getting the clothing wet also.

The HR Transmitter may not be positioned correctly.
Make sure the grooved sensors are flat against the skin.

Heart rate reading on watch is erratic or stops:

You may need to replace the battery in the HR Transmitter .

Sources of electromagnetic fields like appliances, computers and power lines can cause interference. Change your location.

This product complies with EN60601-1-2

Watch display is frozen:

The display of your watch may "freeze" due to static electricity or recent battery replacement. If this occurs, press and hold both buttons at the same time. This will erase the data in the memory and allow you to reset the watch to the factory settings.
