Footswitch
The footswitch is connected to the Cryomatic at the rear of
the console. The footswitch is not a serviceable item and if
it is faulty then it should be returned to the manufacturer for
replacement.
Controller PCB Assembly
Observe proper precautions for the prevention of damage
to static sensitive devices.
The Controller PCB Assembly can be removed in the
following manner.
a) Unlatch the connection for the LCD panel in
position CN1. Carefully withdraw the flexible cable
assembly.
b) Unplug the front panel membrane connector in
position CN13.
c) Remove the 6 pozi pan-head screws that secure the
PCB to the enclosure (being careful to retain all
washers).
d) Withdraw the PCB from the enclosure.
e) Re-fitting is the reverse of removal. Care should be
taken when re-connecting the LCD flexible cable
assembly as this is easily damaged. Ensure that the
latch is closed properly.
