Wearing the Watch

If the strap connected to the CS Watch 3 is too short, replace the strap with the longer strap provided with the CS System 3 (see item 4 Figure ‎4‑1).

To remove the strap:

  1. Turn the watch over to see its backside.
  2. Slide the small silver spring lever inwards.
  3. While under compression (spring-loaded), gently rotate the strap, pivoting around the stationary end.
  4. Remove the strap.

 

To connect the replacement strap:

  1. Insert the pin on the far end from the silver lever into the small cavity in the watch strap holder/lug, as shown in section 3
  2. Slide the small silver spring lever inwards (as shown in section 2), and while under compression (spring-loaded), gently rotate the strap into place, pivoting around the stationary end (see section ‎3).
  3. Insert the pin on the silver lever side into the other small cavity in the watch strap holder/lug. A click may sound when the pin enters the cavity.
  4. Gently push or pull the strap to hear a click and ensure the strap is firmly connected to the watch.

When the watch is fully charged, wear it on your left or right wrist, just above the wrist bone, over intact skin.

Tighten the strap so that the watch is in full contact with your skin and feels comfortable. Do not overtighten the watchstrap. A too loose or too tight watch strap may affect measurement results.

Once your CS Watch 3 and smartphone are paired, the watch starts monitoring your pulse rate. You may close the app; the watch continues monitoring your pulse rate even when the CS3 Mobile app is closed.

Warning:

Low skin temperature, restricted blood flow, or excessive movement may result in a lack of measurements. In such cases, remove the watch from your wrist, warm your hands and place it back on.

The CS Watch 3 is categorized as IP-67, meaning you may use the watch during exercise, rain, and while washing your hands or taking a shower.
