The chest strap comes with a pre-installed CR2 battery. If replacement is needed, refer to the Maintenance section.

- The moistened electrodes should be in firm contact with your skin.
Drift
1. Pairing with Your Heart Rate Monitor
The Sigma Analog Chest Strap is designed to work with compatible analog heart rate monitors. Typically, no manual pairing is required as the analog signal is continuously broadcast. Simply ensure your heart rate monitor is turned on and within range.
2. Start din træning
Once the chest strap is correctly worn and the electrodes are moistened, your heart rate monitor should automatically detect the signal. Begin your activity as usual. Your heart rate will be displayed on your compatible device.
3. Ending Your Workout
After your workout, remove the chest strap. It is recommended to clean the strap immediately after use (see Maintenance section).
Opretholdelse
Rensning
- After each use, rinse the chest strap under running water to remove sweat and salt residue.
- Wipe the sensor module with a damp klæde. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Allow the strap to air dry completely before storing. Do not machine wash or tumble dry.
Udskiftning af batteri
The chest strap uses a CR2 battery. When the battery is low, your heart rate monitor may display an indicator or show erratic readings. To replace the battery:
- Åbn forsigtigt batterirummet på bagsiden af sensormodulet med en lille mønt eller et passende værktøj.
- Fjern det gamle batteri.
- Indsæt et nyt CR2-batteri med den positive (+) side opad.
- Luk batterirummet forsvarligt, og sørg for, at forseglingen sidder korrekt for at opretholde vandtætheden.
Opbevaring
Store the chest strap in a cool, dry place away from direct sunlight and extreme temperatures.
