1.1.1 Removal and replacement of the detector front cover
To remove the front cover, unlock it using the key provided (turn anticlockwise). The bottom of the front
cover may then be lifted away from the detector chassis until the top of the cover disengages from the
retaining rails at the top of the chassis. The cover may then be removed.
If greater internal access is required, for example for software upgrades, it may be necessary to remove
the LCD display board. To do this, unfasten the four counter-sunk crosshead screws holding the display
to the display mounting brackets
