My Philips Avent digital thermometer shows a dot on the display

Replace the battery as soon as you see the battery indicator to ensure the accuracy of your thermometer.

Instructions on how to replace the battery

1. Gently squeeze the side of the cap to remove
2. Carefully remove the battery from the tray. Note: do not pull out the battery tray (A) more than 1cm, otherwise the sensor might break off. You have to pull it out a little bit to get to the battery.
3. Insert the new battery
4. Place the cap back on the thermometer

NOTE: Batteries contain hazardous materials. Make sure that you properly dispose of used batteries.
