branch exchange).
To make an external call
Lift your handset.
Press a free
LINE
button.
Listen for the exchange dial tone.
If you hear the dial tone, dial the number
you want in the normal way.
If the lamp does not glow, it means that
the button you have pressed is not
connected to an exchange line, or the
line is not available to you. Try the other
button.
At the end of the call:
Replace your handset.
A line is free if the lamp next to its
button is out. The lamp glows when
you press the button.
The lamp next to the

If you are using extension 2 you may receive a call from another extension
user who does not have a key module, asking you to make a call on his
behalf. For the procedure to follow, see page
