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 70% size.

Selector 5:
Minimum ON and OFF duration of ringer signals effective in distinctive ringing
The ringer pattern consists of short and long rings, e.g., short-short-long rings. This selector sets the
minimum ON and OFF duration of ringer signals that are required for the machine to interpret ringer
signals as being ON or OFF. This is to prevent components of a ringer pattern from being
misinterpreted due to chattering in distinctive ringing.
The machine monitors ringer signals at 10-ms intervals. If the signal is ON, the machine 1;
if it is OFF, it counts -1. If the counter increments up to +5 or +13 when this selector is set to "1"
(50 ms) or "0" (130 ms), respectively, the machine interprets the current signal as being ON.
If the counter returns to zero, the machine interprets the signal as being OFF.
If the Distinctive Ring is set to OFF, this selector is not effective.
