NOTE: Selectors 1 through 7 are applicable to the European models.
Selectors 1 through 3: Caller ID judgment voltage level to discriminate caller ID event from ring
event
If the machine misdetects a caller ID event as a ring event due to voltage variation, it fails to display
a caller ID. If it happens, increase the judgment voltage level provided that the setting made by these
selectors is equal to or more than the setting made by selectors 4 through 6.
Selectors 4 through 6: Caller ID judgment voltage level to detect line polarity reversal
If the machine fails to detect a line polarity reversal for a caller ID due to a great difference between
the line voltage when a polarity reversal occurs and the one at the steady state, it fails to display a
caller ID. If it happens, increase the judgment voltage level provided that the setting made by these
selectors is equal to or less than the setting made by selectors 1 through 3.
Selector 7: Time limit for judging a caller ID burst ring
The time limit for judging a caller ID burst ring is enabled by default so that receiving a burst ring
out of the specified time limit causes the machine to interpret it as an ordinary call involving no
caller ID signal, resulting in no caller ID display.
When the machine fails to display a caller ID if you have the caller ID subscriber service from your
telephone company, disable the time limit with this selector to receive a caller ID burst ring
independent of the burst ring time.
