< Making a call >

1. Hands-free conversation may be made by simply
touch dialing the station number you wish to call.
2. When you wish to use the handset, pick it up, then
touch dial the station number you wish to call, or
reverse the order.
3. Start conversation after the calling tone stops.
4. When you hear a busy tone that indicates the party
you call is on another line, you can camp on the line
by simply waiting. As soon as the line becomes free,

your call is automatically connected.

5. In the event that the party you are calling does not
respond and the continuous calling tone is still heard
from your station, or when the station of that party
is in the Privacy mode and the Privacy tone is sound-
ed, you can break in on the c alling tone by continu-
ously depressing the key to make a voice call
through the stati on speaker of the c alled party.
6. During hands-free conversation, when the person you
are talking to is in a high noise level area,
(1) Pick up the handset to talk or (2) depress the
key continuously for one-way conversation
to that party. As long as the key is depres-
sed, your voice has dominance, and releasing the
key will reverse the one-way conversation
from that party to you.

or depress the key.
