Although foam swabs can leave filmy deposits, these deposits are very
thin, and the risk of other contamination buildup on the inside of adapt-

2 Clean the adapter with the foam swab.
3 Dry the inside of the adapter with a clean, dry, foam swab.
4 Blow through the adapter using filtered, dry, compressed air.
Nitrogen gas or compressed dust remover can also be used. Do not
shake, tip, or invert compressed air canisters, because this releases par-
ticles in the can into the air. Refer to instructions provided on the com-
pressed air canister.
