When the air duster gas is combustible, do not use it near fire. Doing so could result
in a fire.
Use an air duster specially designed for cleaning optical connectors. Using another
type of air duster could cause the ferrule tip to become dirty.
Keep the nozzle or container of the air duster from coming into contact with the
ferrule tip. Contact could result in a malfunction.
See the instructions of the air duster before use.
