0 If the detector is beeping every 30 seconds and it displays LB it means you need to replace the battery. Disconnect the detector from the wall, replace the battery and then reset the alarm. You can reset the alarm by holding the button on the left, until it clears and beeps. Cover your ears because the it wil start beeping VERY loud for a few seconds while it resets, then it will give you a reading.
