Thanks for the info!

The device did come with paper copies of the appropriate BSP's for identification, maintenance, and connections. Unfortunately, as I do not have the appropriate 565-type set or 6040H key, the connections guide doesn't really explain much of what all the screw terminals are for. When I received it, there were jumper wires on the following terminals:

Between 9 and 10
Between 11 and 12
Between R and 19
Between T and 29
Between G and 38
Between 5, 26, and 36
Between 27, 28, and 37
Between 45 and 46

The cut-off wires were connected as follows:

Black-37
Orange-36
Violet-20
Brown-T
Yellow/Green-23
Yellow-24

Not sure of the significance of these terminals. I do know based on the BSP's my unit is a 'List 2' type, which implies it can be used on ground start lines.
I'd also like to note that it has the operator's headset type jacks with a handset connected to them. When the switch is in the 'check' position, the drum starts rotating and I can hear some noise through the receiver. When the switch is held in the 'dictate' position, the green light comes on and the drum spins. It doesn't seem to want to record anything though.
