11. PRODUCT LIFETIME
It is recommended that you replace your product within
5 years from date of manufacture. The lifetime of the product
will be highly dependent on the environment in which the
product is stored, used, serviced, and maintained. The user
must regularly inspect the product to determine when it has
reached its end of life. Examples that the product may have
reached its end of life are:
• Visible defects such as cracks, deformations, loose or
missing parts.
• Experience of a deterioration in the hearing protector's
attenuation performance, strange noise or abnormal high
sound volumes from the product's electronic sound
reproduction.
NOTE: Product lifetime does not include batteries.
12. CLEANING AND MAINTENANCE
Carry out a visual battery condition check. Replace if battery
leakage or defects are detected.
Use a cloth wetted with soap and warm water to clean the
outer shells, headband and ear cushions.
NOTE: Do NOT immerse the hearing protector in water.
If the hearing protector gets wet from rain or sweat, turn the
earmuffs outwards, remove the ear cushions and foam liners,
and allow to dry before reassembly. The ear cushions and
foam liners may deteriorate with use and should be examined
at regular intervals for cracking or other damage. When used
regularly, 3M recommends replacing the foam liners and ear
cushions at least twice a year to maintain consistent
attenuation, hygiene, and comfort.
