Support Arm Adjustment
Periodically the support arm mechanism may require adjustment.
1.
Remove the cross head arm fixing screw.
2.
Using a suitable screwdriver, turn the tensioning screw (Fig 26) anti-clockwise half a
turn.
3. Refit the leg fixing screw and repeat the operation on the opposite side.
4.
Check that the arm tension is enough to support the weight of the PDU without movement.
VIA Carrying Case
The VIA unit (0018) is secured into its carrying case with two fixing screws from the underside of the case. If a new
VIA is required, remove the two fixing screws and lift the VIA from the carrying case. Return only the VIA for
