Replacing the battery | P-DISC NO1

It’s easy changing the battery in your OOONO P-DISC NO1. Simply follow these steps: 

Replace the battery

1. Pull the P-DISC NO1 off the magnets on the car glass.
2. Place the P-DISC NO1 in one hand, with the display facing the palm of your hand and the P-DISC NO1 positioned with “CE” engraving closest to you.
3. With the other hand, insert a fingernail or a small flat screwdriver into the crack just below the “CE” and the waste bin engraving to loosen the battery cap.
4. Pull out the battery cap from the P-DISC NO1.
5. Replace the battery with a new CR2450 battery and reinsert the cap with the new battery.

Remember to set the time and date again, after the battery replacement.
