Cleaning, safety and maintenance
Clean the headset, including the headset boom and ear loop piece, by wiping with a slightly damp cloth
as required. Dampen the cloth with only water and a little washing-up liquid if needed.
Avoid getting moisture or liquid into any button sockets or other openings. The base and cords
may be dry-dusted as required.
The ear cushion and ear plate may be cleaned or replaced. When cleaning, use water only and a little
washing-up liquid if required.
• To clean or replace the ear plate, first remove the ear plate from the headset receiver.
• To clean or replace the headset’s ear cushion, gently peel it off the ear plate.
• Do not immerse the GN 9120 in water.
• For your convenience, replace ear cushion once a year.
