How to Use a Triax C5

The Nike Triax C5 is a watch that displays heart rate, total workout time, and the time and date. The watch has an S-shaped polyurethane strap and a scratch-resistant mineral glass crystal display. The C5 includes an adjustable chest strap transmitter for accurate heart rate measurement. The watch can be worn for underwater activity up to 50 meters deep. The Triax C5 has a two-year limited warranty but as of 2011 is no longer available at Nike's online store.

Instructions

  1. Nike Triax C5 in RUN Mode

    • 1

      Push one end of the heart rate transmitter tab through the slot and press down until flat. Place the heart rate monitor strap around your bare chest so that it rests on your rib cage just below the breast plate. Close the other end of the tab. The strap should be snug enough that it does not slip while exercising. Wet the grooved areas on the back of the heart rate transmitter to facilitate the pulse rate reading. The heart rate transmitter reads the electrical impulses of your heart and sends the data to your Triax C5 watch. The transmitter can transmit data up to 30 meters underwater.
