Set distinctive ring
Ring-pattern or distinctive-ring service is available through some local telephone companies. The service
provides a way to have more than one telephone number on a single line. Each telephone number has a
unique ring pattern, so that you can answer voice calls and the product can answer fax calls.
If you subscribe to a ring-pattern service with a telephone company, you must set the product to answer the
correct ring pattern. Not all countries/regions support unique ring patterns. Contact the telephone company
to determine if this service is available in your country/region.
NOTE: If you do not have ring-pattern service and you change the ring-pattern settings to something other
than the default, All Rings , the product might not be able to receive faxes.
The settings are as follows:
● All Rings : The product answers any calls that come through the telephone line.
● Single : The product answers any calls that produce a single-ring pattern.
● Double : The product answers any calls that produce a double-ring pattern.
● Triple : The product answers any calls that produce a triple-ring pattern.
● Double and Triple : The product answers any calls that produce a double-ring or triple-ring pattern.
