Cleaning Connector Interfaces
Caution
Be careful when using pipe-cleaners, as the core and the bristles of the pipe-cleaner are hard

Do not use pipe-cleaners on optical head adapters, as the hard core of normal pipe cleaners can
damage the bottom of an adapter.
Preferred 1. Clean the interface by pushing and pulling a new, dry pipe-cleaner into the
Procedure opening. Rotate the pipe-cleaner slowly as you do this.
2. Then clean the interface by rubbing a new, dry cotton-swab over the
surface using a small circular movement.
3. Blow away any remaining lint with compressed air.
Procedure for Use this procedure particularly when there is greasy dirt on the interface:
