Call button
Press this momentary button to send a signal to the control panels calling for attention. The
ND/RE indicator in the viewfinder shows when a call signal is sent or received.
The call button can also be used to playback a voice mail message that has been recorded in
the base station. Press once to start playback; press again to stop.
Data channel
The Aux connector on the side of the adapter provides analog control signals and allows for the
connection of a two-way private data channel between camera and base station.
Tracker tally signal
The tracker connector on the side of the adapter, as well as providing full intercom facilities for
the dolly or crane driver, also carries a tally signal and a 12 VDC power supply. This allows an
external On Air lamp to be used.
