"Why doesn't my caller ID work?"に関する回答Caller ID is a subscription service. You must subscribe to this service from your telephone service provider for this feature to work on your phone. The caller may not be calling from an area that supports caller ID. Both your and your caller’s telephone service providers must use caller ID compatible equipment.
"Why is my device not recording any messages?"に関する回答Make sure the answering system is on. ANS ON light on the telephone should be on. Make sure the memory of the answering system is not full. If there is a fax machine connected to the same telephone line, try disconnecting the fax machine. If that solves the problem, consult your fax machine documentation for information on compatibility with answering systems
"How come I can hear other calls while using my phone?"に関する回答Disconnect the telephone from the telephone jack, and plug in a different telephone. If you still hear other calls, call your telephone service provider.
