Yes, it is possible to record an intercom conversation for up to 4 users. The procedure for this operation is:

1. Connect headset to up to 4 mobile units
2. Set up a conference call (refer to instruction manual) with up to 5 mobile units and leave one of them in the master slot (left slot) of the docking station.
3. Press the AUX button down on the docking station, to connect the conference call to the AUX connection instead of the telephone.
4. Now use the AUX-multimedia-PC cable included in the DW 800 package to connect to a tape recorder. Remember to adjust the recording level on the tape recorder.

Please note that in most countries, legal restrictions apply to the recording of telephone conversations.
