• Do not adjust a bit switch or use a setting that is described as "Not used", as this may cause
the machine to malfunction or to operate in a manner that is not accepted by local regulations.
Such bits are for use only in other areas, such as Japan.
Default settings for bit switches are not listed in this manual. Refer to the System Parameter List printed
by the machine.
