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.
