Usage Features
Insertion:
- Ensure earplugs are clean before insertion.
- Hold the end of the earplug between your thumb and index finger.
- To facilitate insertion, use your free hand to pull the top of your ear outward and upward. This action straightens the ear canal, allowing the earplug to fit easily and effectively.
- Gently push and twist the earplug until it forms a comfortable seal in the ear canal.
- Apply enough thumb pressure during insertion for the earplug to move slowly into the ear.
- Crucially, avoid over-inserting the earplug and ensure that the tab remains protruding enough for easy removal after use.
Removal:
- Gently grasp the end of the earplug with your thumb and index finger.
- Slowly pull the earplug out of the ear.
- The removal process should not be painful. If pain occurs, contact a medical professional.
Important Usage Considerations:
- The effectiveness of the earplugs is influenced by the user's ear size and shape, as well as the noise levels in the environment where they are used.
- Always wear the earplugs in noisy surroundings.
- The earplugs must be properly fitted, adjusted, and maintained according to these instructions.
- Do not use these earplugs if there is a risk of the connecting cord (if applicable) getting caught during use.
Safety Warning:
- Keep away from infants and small children. This product is non-toxic, but if swallowed or if the cord wraps around the neck, it could interfere with breathing, leading to serious injury or death.
- Improper fitting or disregard of recommendations can reduce effectiveness, potentially leading to hearing loss or injury.
- If the provided recommendations are not followed, the protection offered by the earplugs will be severely compromised.
- The earplugs may react with certain chemical substances. For more information, consult the manufacturer or visit www.schallwerk.eu.
Maintenance Features
Cleaning:
- The earplugs are reusable and should be regularly inspected for serviceability.
- After use, clean the earplugs with neutral soap and lukewarm water to disinfect them.
- Ensure the earplugs are completely dry before re-inserting them into the ear.
- Store the earplugs in a cold, dry place after use, preferably in their protective case.
Storage and Lifespan:
- The earplugs are designed to be used within a temperature range of -20°C to 35°C.
