Dismantling the Workabout
The modular design of the Workabout is such that the internal workings of the product can be
removed from the case by removing two screws. This means that if the outer case assembly
becomes damaged, it can be replaced quickly and easily without the need to change any
other component. If there is a fault in the Outer Case Moulding, LCD Window, Keyboard
Frame, or Rubber Keymat, the entire case should be replaced.
+
Note:- In some cases the machine may be fitted with security screws that require a suitable
screwdriver to remove them.
When you remove internal components from the case, take care not to damage the LCD
Module. Do not bend the Module, as it is prone to fracturing. Do not touch the LCD Glass as it
will show finger marks and smudges.
If the LCD glass is broken, be careful not to get any liquid in your mouth or eyes. In the event
of any liquid crystal getting on skin or clothes, wash it off immediately with soap and plenty of
water and seek a doctor’s advice.
