Note: Selector 5 is applicable only to the U.S.A. models.
• Selector 2: Limitation of reduction ratio in copying
When the user selects a ratio less than 70%, if the reduction ratio is limited ("0"), the
machine prints in 70% (fixed); if not limited ("1"), the machine prints in the reduction ratio
matching the horizontal scanning width of recording paper.
• 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-millisecond 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" (90 milliseconds) or "0" (130 milliseconds), 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.
