Slide the wedge adaptor operating lever (1) forward (parallel to the wedge) about 6 mm (1/4 in.)
against spring tension. Pull the operating lever out, away from the body of the wedge adaptor, as
far as it will go.
Insert the camera wedge into the wedge adaptor and push it forward into full engagement. Push in
the operating lever (1) until it lies parallel with the wedge adaptor body. During this operation re-
sistance of the spring-loaded over-centre mechanism will be felt. As the lever reaches the end of
its travel it will slide back (parallel to the wedge) to the locked position.
Confirm that the lever is in the locked position. This is indicated by coloured bands above the lever.
When the green band only is visible, the lever is locked. If any of the red band can be seen, the
lever is not locked.
Install the remainder of the payload (lens, zoom and focus controls, viewfinder, prompter etc.).

Connecting the head

The encoder connector (26) connects directly to the 'Active Serial Box' which attaches to the mounting
holes (22) on the underside of the head. For more information refer to the Active Serial Box Operators
Guide (Publication Part No. V4039-4980).
Pan(23) and tilt (24) axis data indicators illuminate when an Active Serial Box is connected and switched
on, signifying the axis encoders are powered and providing output data.

Stability

When mounting the pan and tilt head on a tripod, it is possible to set the tripod legs so that the centre-of-
gravity of the tilted payload falls outside of the footprint of the tripod, leading to instability.
WARNING!
1. Always use a mid-level or floor spreader to ensure that the tripod legs
are spread sufficiently so that the centre-of-gravity of the tilted payload
remains within the footprint of the tripod.
2. Where possible, use the tie-down hook on the tripod for additional stabil-
ity.

Balancing the head

NOTE: It is important that the pan bar(s) and all camera accessories (lens, zoom and focus
controls, viewfinder, prompter etc.) are fitted in their operational position and the system
connected before balancing the head. Any equipment fitted or adjusted later will
unbalance the head.
Balancing the Vector 950 OE head achieves two objectives. Firstly, when a head is correctly balanced the
operator will need a minimum amount of even effort to move the head. Secondly, once balanced, the head
and its payload can be set to any tilt position and the head will maintain this position with 'hands off'.
The graph (Fig 3) shows the range of load and C of G height that can be maintained in balance. The shaded
area of graph corresponds to those load/C of G combinations that can be balanced over the full tilt range.
The area to the right indicate the progressively reducing tilt range with greater load and higher
C of G.
Fore and aft balance
When positioning the payload it is important to be aware of the potential danger of an unbalanced payload
falling away suddenly. Before disengaging the centre lock, set the balance adjustment knob (5) to its mid
point setting (50 on the digital display). Depending on the payload weight, it may be necessary to increase
or decrease this setting to enable the payload to be correctly balanced fore and aft.
Balance the payload fore and aft as follows:
