Selector 2:
Default reduction rate for failure of automatic reduction during recording
This selector sets the default reduction rate to be applied if the automatic reduction function fails
to record one-page data sent from the calling station in a single page of the current recording
paper.
If it is set to "0," the machine records one-page data at full size (100%) without reduction; if it is set
to "1," the machine records it at the size* specified according to the current paper size.
(*American versions allow the user to select the desired paper size from the control panel. According to the
paper size setting, the machine determines the reduction rate. Other versions can handle only A4-size
paper, so the reduction rate is always 87%.)

Selector 5:
Minimum short-OFF duration in distinctive ringing
The ringer pattern consists of short and long rings, e.g., short-short-long rings. This selector sets
the minimum OFF duration following a short ring in order to avoid missing ringer tones in
distinctive ringing.
If this selector is set to "1," when the short-OFF duration is a minimum of 90 ms long, then the
machine will interpret the short-OFF as OFF.

Selector 8:
"CHANGE DRUM SOON" message
This selector determines whether or not the "CHANGE DRUM SOON" message should appear on
the LCD when the service life of the laser-sensitive drum in the laser unit will expire soon.
