The Omron TH839S thermometer emits 4 beeps when checking the temperature in the ear and not providing a reading. This may indicate a problem with the measurement process or the thermometer itself. Here are some steps you can take to troubleshoot the issue:1. Ensure that the probe is clean and free from any obstructions. Clean the probe with a soft cloth or cotton swab before each use.2. Make sure the probe is inserted correctly into the ear canal. Gently insert the probe into the ear and position it securely.3. Check the battery level of the thermometer. If the battery is low, replace it with a new one.4. Confirm that the thermometer is in the correct mode for measuring ear temperature. The thermometer should be set to the ear mode, indicated by an ear icon.5. If the problem persists, contact Omron customer support for further assistance.

I suspect the battery is hidden under the front of the thermometer where the OMRON logo is. I’ve tried but can’t get the battery out to replace it. Where is it hidden? Are there any tricks to help open the thermometer to access it? I’m worried if I use a knife to pry it open that it will break. Couldn’t find any info on the instruction manual.
