- 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
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.
