Lift the edge of the microboard to reveal the
touch-screen flexi cable, and disconnect it. Place
the board in a static safe area until needed during
re-assembly.
In accordance with the manufacturer’s instructions for use,
and details provided by the manufacturer’s Safety Data
Sheet (MSDS), use a commercial ‘Freezer spray’ (available from most electronics distributors) to freeze the gasket located between the touch screen and the door. Run
the spray tube twice round the whole frame, at moderate
speed to ensure that all the gasket is frozen. Continue at
step 7 as soon as possible.
4
Remove the front cover of the recorder by undoing
the remaining four securing screws (two each side)
!
WARNING,
The next step involves using a sharp blade to remove a glass sheet from its mounting. It is recommended
that eye protection be worn, to guard against glass ingress should the touch screen break. When using
the blade, it should always be moved in a direction away from the user, and it should be ensured that,
should the blade break or slip, no contact would be made with either the person carrying out the procedure or by any nearby personnel.
The manufacturer accepts no responsibility for any damage to personnel, or their property resulting
from the carrying out of this procedure.

With the gasket frozen, use a sharp ‘Craft knife’ or similar to
separate the touch screen from the gasket. (It is likely that some
damage to the touch screen will occur during this process.)
E
D
Carefully, but firmly, press down on the touch screen to separate
it from the cover’s metal frame.
5
Remove the six securing screws from the display
backplate.
The backplate and the display can now be pulled
away carefully from the cover, using one or both of
the upper brackets ('D' in the figure). Lay the assembly to one
side, in a static safe area.
D
Discard the touch screen.
C
8
Carefully use a craft knife or small screwdriver blade
to lift a portion of the remaining part of gasket away
from the frame. Once loosened, it is normally possible just to pull the remainder away, as shown.
CAUTION
On some versions of the recorder, the display is secured only near its top edge. The lower edge
of the display ('E' in the figure) is not secured to the chassis and the display should therefore be
supported by hand, as it becomes accessible.
Once the gasket has been removed, ensure that the
frame is clean, so that the new gasket can make good
contact with the frame.
Note: For current versions of the recorder, the upper brackets are joined to the lower brackets by metal support straps
