If you notice that your thermometer is showing an intermittent or jumping temperature, please first check that the jack plug is pushed fully into the back of the jack socket at the rear of the thermometer.
It can sometimes be a little difficult to push it all the way in. If it is not pushed all the way in, it's very likely you will see an intermittent/flashing temperature reading.
If you continue to experience problems after this, please reach out to our Customer Experience team who will be happy to help further.
