- Make sure you are wearing your smartwatch higher and tighter on the arm with the sensors flat against your skin above the wrist bone.
- Temperature, sweat, irregular movement, and tattoos can cause interference. Keep the smartwatch as still as possible and remove any condensation between device and skin.
- If you have tattoos on your wrist, the sensors may not be able to get a reading. Wear your watch on the other hand if the skin is clear.
- If you have poor circulation or are cold, warm up first before starting your exercise to help improve heart rate readings
Note: Pertains to the Touchscreen Smartwatch HR only.
