with a new one according to the following instructions.
Warning!!!:
Safely dispose of the old batteries, and do not place them within reach
of children. If a battery is swallowed, consult a doctor immediately.
When any battery for the wristwatch, heart rate sensor, or speed sensor is depleted, *
we recommend replacing all batteries at the same time.

cover and the o-ring are dirty, wipe off carefully and check that it is installed properly.
