3. Setup
Before each temperature measurement, a new, clean lens filter must be attached to the Braun ThermoScan ear thermometer. This ensures both hygiene and measurement accuracy.
- Remove from Packaging: Take one new lens filter from its box. Avoid touching the tip of the filter to maintain sterility.
- Attach to Thermometer: Gently push the lens filter onto the thermometer's probe until it clicks into place. Ensure it is seated firmly and correctly.

4. Operating Instructions
The lens filter is an integral part of the Braun ThermoScan ear thermometer's operation. Follow these steps for accurate temperature measurement:
- Prepare Thermometer: Ensure a new, clean lens filter is used for each measurement (refer to Section 3: Setup).
- Power On: Press the power button on your Braun ThermoScan thermometer. Wait for the readiness indicator (usually a beep or a specific symbol on the display) before proceeding.
- Position in Ear: Carefully insert the thermometer probe, with the attached lens filter, into the ear canal. Ensure the probe is aimed towards the opposite temple for optimal accuracy.
- Take Measurement: Press the measurement button. The thermometer will typically beep to indicate that the measurement is complete, and the temperature reading will be displayed.
- Remove and Dispose: After taking the temperature, press the eject button (if available on your model) or gently pull the used lens filter off the probe. Dispose of the used filter immediately in a waste bin.
- Power Off: Turn off the thermometer or allow it to power off automatically.
Important: Always use a new lens filter for each measurement to prevent the spread of germs and ensure accurate readings. Reusing filters can lead to inaccurate results and hygiene risks.
5. Maintenance
Maintaining your Braun ThermoScan Ear Thermometer Lens Filters is straightforward due to their disposable nature. Proper handling ensures the longevity of your thermometer and the accuracy of its readings.
- Single Use: Each lens filter is designed for a single use only. After each temperature measurement, remove and discard the used filter.
- Storage: Store unused lens filters in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures.
- Thermometer Cleaning: While the lens filters protect the probe, it is advisable to occasionally wipe the exterior of your thermometer with a soft, dry cloth. Do not immerse the thermometer in water or use abrasive cleaners.
- Inspection: Before attaching a new filter, quickly inspect the thermometer probe for any debris or damage.
