Selector 1: Definition of programmable key
This selector defines a programmable key as a TEL key or TEL/POLLING key.
Setting this selector to "1" allows the programmable key to function as either a TEL or POLLING
key if pressed when the handset is off or on the hook, respectively.
Selector 2: Ringer OFF setting
This selector determines whether or not the ringer can be set to OFF.
Selector 4: Detection of distinctive ringing pattern
If this selector is set to "1," the machine detects only the number of rings; if it is set to "0," the
machine detects the number of rings and the ringing time length to compare the detected ringing
pattern with the registered distinctive one.
