< Making a call >
1. For hands-free conversation, touching the key
makes a call to the designated other station whether
the Privacy switch on your station is in the ON posi-
tion or OFF position.
[In the case that the Privacy switch is in the OFF posi-
tion.]
2. When you wish to use the handset, pick it up, then
touch dial the key to make a call or reverse the
order.
[In the case that the Privacy switch is in the ON posi-
tion.]
3. Picking up the handset makes a call to the designated
other station.
4. Start conversation after the calling tone stops.
5. 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.
6. In the event that the party you are calling does not
respond and the continuous calling tone is still heard
from your station, you can break in on the calling
tone by continuously depressing the key to
make a voice call through the station speaker of the
called party.
7. 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 de-
pressed, your voice has dominance, and releasing
the key will reverse the one-way conversa-
tion from that party to you.
8. To terminate the conversation, hang up the handset
or depress the key.
< Responding to a call >
[In the case that the Privacy switch is in the OFF
position.]
9. Respond to call after the calling tone stops.
[In the case that the Privacy switch is in the ON posi-
tion.]
10. The continuous calling tone function is made avail-
able to any station when its Privacy switch is in the
ON position. Depressing the or key or picking
up the handset of the station called makes the con-
tinuous calling tone stop and puts the station in the
conversation mode.
