*1 When file devices with PC part numbers or commercially available file devices are installed, the installation environment conditions are the environmental conditions of the extended options. The clock in the main unit may deviate when stored in a location having an ambient temperature of 0 degree C or lower. Reset menu before use.
*2 Information in parentheses ( ) is when the accompanying dust-proof filter (for front side) or optional dust-proof filter (FC-FL006R) is installed.
*3 The storage temperature for keyboard and mouse is -20 to 60 degrees C for FC-KB005 / FC-MS003.
*4 Put FC-D21A / FC-D18M into a dust-proof rack, air-tight case, or the like when using in a dusty location or in an environment with metal powder, oil mist, corrosive gases, etc.
*5 There is no guarantee of resistance against resonance effects that may occur when a sound at or near this unit's natural frequency occurs or that are caused by the sound from the built-in speaker.
*6 The built-in power supply unit in the main unit has an improved power factor.
