USING
To store a pause in a stored
number
A pause is sometimes required
with some switchboards and
Network Services.
A pause simply gives the
switchboard a few seconds to
pick up the outside line before
dialling. Using the
Redial
button, you can insert a pause
when you store a number in
the directory.
Repeat the steps for storing a
number in the directory but
press the
Redial button where
you want to add a pause within
the number.

Your Converse 425 provides all the
basic calculator functions – addition,
subtraction, multiplication, division and

and

If the phone rings while you are using
the calculator function, simply lift the
receiver or press the
Handsfree button
as normal. Note that information
entered in calculator mode will be lost.
