Replace the NOBL Air+ battery
- Find the small gap on one edge of the tracker.
- Gently twist a plastic pry tool in the gap until the cover lifts. Don't use a knife or anything sharp.
- Peel the halves apart with your fingers.
- Swap the old battery for a new CR2032, with the + side facing up. The red light blinks three times when it's in the right way.
- Line the halves up and press around the edge until it clicks shut.
If the circuit board falls out
Line its three holes up with the three pins inside the case and press it gently back into place before closing.
Coin batteries are dangerous if swallowed
Keep them away from children. If one is swallowed, get medical help straight away. A battery fitted upside down can drain at once, so if the light doesn't blink, try a new one.
