12. Repair and Replacement
If a lanyard must be constructed locally in emergency, it should have an internal length, measured over 8mm
pins, of 98.5cm.
Servicing the Surface Electronics
Some items are SENSITIVE TO ELECTROSTATIC DAMAGE and must be handled accordingly.
Be careful not to stress cables or connectors when disassembling equipment.
Before removing any component or internal cable, observe carefully how it is secured and replace it exactly
as found.
Consult the local C-MAX representative or the factory for advice.
Servicing the STR
To gain access to the internal parts of the STR remove the three M3 screws at the lower rear of the unit and
carefully slide the chassis out.
Take care when replacing the chassis not to trap the LED leads between the chassis and the top of the
enclosure.
Servicing the C-Shell
To gain access to the internal parts of the C-Shell release the black plastic panel (STR base) and then
remove the two M3 nuts holding the black anodised cover from the connector panel. This reveals the printed
circuit board mounted on the back of the connector panel that carries the 20x5mm 10A fuse in the DC supply
to the STR. This PCB also includes the 12V regulator for the fan and power LED.
Servicing the C-Case 2
To gain access to the internal parts of the C-Case 2 remove the eighteen M3 screws securing the edge of
the main panel. Do not attempt to remove any of the screws visible on the outside of the case.
Carefully lift out the panel and examine for defective components or connections.
Note that the monitor panel is a sealed unit. Do not attempt to remove the screws on its upper edge. A
defective monitor must be returned to C-MAX for repair. An external monitor can be used in the absence of
the normal unit.
Servicing the C-Case SE
To gain access to the internal parts of the C-Case SE remove the eighteen M3 screws securing the edge of
the main panel. Do not attempt to remove any of the screws visible on the outside of the case.
Carefully lift out the panel and examine for defective components or connections.
