Cleaning the dust filter
Your LIFEBOOK is equipped with fans to make air flow inside by pulling in outside air to cool the inside of the system.
Depending on the environment in which the system is used, dust and dirt may be pulled in along with the air.
Accumulated dust and dirt could impair the function of the system.
