The cable from the Temperature probe socket plugs into connector PL14 on the Main Board and is easily
removed.
The SpO
2
cable runs from the small front panel connector printed circuit board to another small PCB with
integral connector attached to the Nellcor Puritan Bennett
™
module. To remove the PCB from the front
panel, locate and remove the two small Pozidriv
™
retaining screws, which fix the PCB metal support bracket
to the front panel. The cable and PCB assembly can then be lifted away.
Finally remove the two rubber hoses, disconnect the pump hose at the pump and pressure sensor hose
from the front panel, noting their routing. The front panel can now be lifted away.
3.4.2 Removal of the Switch board, Display board and Liquid Crystal Display
module
The switch board, display board and LCD module are held in place with Pozidriv
™
screws which, in some
cases, also hold the RFI earthing fingers in position. When removing the boards, note the orientation of the
copper RFI earthing fingers so that these can be replaced in the same position later.
