Set number of rings
You can set the answering system to
answer an incoming call after two, three,
four, five or six rings; or toll saver.
If you choose toll saver, the answering
system answers a call after two rings

after four rings when you have no new
messages. This enables you to check
for new messages and avoid paying
unnecessary long distance charges if
you are calling from outside your local

answers an incoming call after three
rings.

phone is not in use.

6, 5, 4, 3, 2 or Toll saver.
• Toll saver - the answering system
answers a call after two rings
when you have new messages, or
after four rings when there is no
new message. This feature allows
you to check for new messages
and avoid paying long distance
charges when calling from out of
your local area.
6. Press MENU/SELECT to save.
NOTE
• If Smart call blocker is on, the first
ring of all calls will be muted.
