If a connection already exists between standard unit 2 and the base unit when standard unit 1 sets up a

connection with the base unit, the connection between standard unit 2 and the base unit is retained and

the base unit switches over automatically to three-party conference mode.

Subsequently duplex communication (speech and simultaneous listening) is possible for the three

parties. In the case of communication sets with PTT button, press the PTT button and keep it pressed

while speaking (see section 2.10).

Connection release

Press one of the three push-buttons in the middle of the push-button bank on the standard unit 1. The

standard unit 1 disconnects itself from the base unit. A high beep tone then sounds in the

communication set of the standard unit 1 and of the base unit. If a connection still exists at this time

between the base unit and standard unit 2, the connection between the base unit and standard unit 2 is

retained. Not until one of the three push-buttons in the middle of the push-button bank on the standard

unit 2 has been pressed does standard unit 2 disconnect itself from the base unit.
