nect the CEP connector end from the helmet connector before removing the helmet. If
you are wearing a CB protective mask, remove the helmet; disconnect the extension ca-
ble from the helmet; disconnect the extension cable from the CEP after removing the CB
protective mask; and proceed with Step 3.
2. Remove the helmet.
3. Remove each earplug by grasping the housing and pulling the earplug out of the ear.
4. Store the CEP in the container provided.
5. Store the CEP extension cable in a marked container so that it is available when
c. Care of CEP
Do not leave the CEP attached to the helmet when not in use; always store the CEP
in the container provided.
When the foam tips become soiled, remove them from the earplugs. Hand-wash
the foam tips with warm water and mild soap, and allow them to air-dry. Do not wash
the foam tips any more than necessary (about once a week); the more often they are
washed, the sooner they will wear out.
With normal use, the foam tips will last about one month. Discard the foam tips if the
foam is degraded or pulled away from the plastic tube inside.
