TROUBLESHOOTING
FM and DAB reception
Check that the batteries are new or fully charged.
The quality of radio reception may vary depending on the
topography or the your environment you are in.
If reception is poor, try moving to a different area if
possible.
CLEANING AND MAINTENANCE
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 24h 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
