Making conference calls with the DW 800 system
Up to four persons can make a conference call and
telephone simultaneously with the same party.
You require a mobile unit with a headset for each
participant in the conference call.
Attention!
Do not recharge the rechargeable battery of a
mobile unit during a conference call as this will end
the conference mode immediately!
Setting up the DW 800 system for conference calls
To initiate the conference mode:
왘
Place a mobile unit into the left-hand charging slot
of the docking station.
This mobile unit becomes the master mobile unit
and is able to control the other mobile units
participating in the conference call.
왘
Initiate an outgoing call or accept an incoming call
(see “Telephoning with the DW 800 system” on
page 16).
왘
Press the program key on the master mobile unit
and keep it pressed for four seconds.
The master mobile unit starts beeping in a high
tone three times a second, thus indicating
conference initialization mode.
The mobile unit belonging to the master mobile
unit automatically participates in the conference
call without the necessity of making further
settings.
