Note: Selectors 1 through 7 are applicable to the European models.
Note: Selector 8 is applicable to models with a cordless handset.
• 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 (Not used.)
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.
• Selector 8: Start key on the machine after dialing with cordless handset (Not used.)
Pressing the Start key on the machine to send a fax during a telephone conversation with
the cordless handset cannot start a sending operation by default. Setting this selector to "1"
enables the
Start key pressed even after dialing with cordless handset.
