Instruction for use
Ear defenders are personal protective equipment that reduces the impact of noise on hearing.
Product / model: Models 4957000, 4958000, 4959000, 4960000, 4961000 are headband ear defenders with height-adjustable capsules and replaceable ear pads (TPE/PU), capsule foam inserts and capsule retainers (stainless steel or plastic).
Recommendations
- The user should ensure that the ear defenders are correctly seated, well-adjusted and serviced in accordance with the manufacturer’s instructions.
- Ensure that you always wear the ear defenders in all noisy environments and that the maintenance requirement is determined at regular intervals.
Caution
- A non-adherence to these recommendations results in a great reduction in the protective effect of the capsule ear defenders.
