• Selectors 1 through 4: Min. detection period required for interpreting incoming
If the machine detects the OFF state of a CI signal for the period greater than the value set
by selectors 1 and 2 and less than the value set by selectors 3 and 4, it interprets the CI
signal as OFF.
• Selectors 5 and 6: Min. detection period required for acknowledging incoming
calling signal (CI) as ON
These selectors set the period required to make the machine acknowledge itself to be
called. That is, if the machine continuously detects a CI signal with the frequency set by
selectors 1 through 4 on WSW14 during the period set by these selectors 5 and 6, then it
acknowledges the call.
• Selector 7: Line connection timing
If a line is connected in a ringer-ON period, FAX models equipped with SDAA circuits may
malfunction due to the ringer voltage. To make the line connection stable, this selector
should be set to "0" so that a line is connected in a ringer-OFF period.
