Instruccions de funcionament
Once installed, the earmuffs can be easily adjusted for active use or stowed when not needed.
Deploying for Use
- To deploy the earmuffs, grasp each ear cup and pivot them downwards until they cover your ears completely.
- Ensure the ear cushions form a tight seal around your ears. Adjust the position of the ear cups slightly to achieve the best fit and seal. A proper seal is essential for effective noise reduction.
- The cushioned ear pads are designed for comfort during extended wear.

Stowing When Not in Use

- Gently push each ear cup upwards until they rest against the sides of the hard hat, out of the way.
- This allows for easy transition between noisy and quieter environments without removing the hard hat.
