starts to play back the greeting and records incoming messages. There
are three options of ring time. Select the ring time by setting the
RINGER SELECT switch.

TS (Toll Saver) If new messages have been recorded, the phone
answers at the second ring and records incoming
messages; if no new messages are recorded, it
answers at the fifth ring. When you call from an
outside phone and hear three rings, you know that
there are no new messages. If you hang up at this
point before the phone answers, you can save the
toll for the call.
5 The phone always answers at the fifth ring and
records incoming messages.
2 The phone always answers at the second ring and
records incoming messages.
