keys have fi xed functions in the immediate and setup modes, but can also
be assigned various functions in Intermec Fingerprint programs. In IPL,
the keys are not user-programmable.

pcb.

of the front moulding. There are one slot for the display and another for
the cable running from the membrane-switch keyboard to the console pcb.
Two brackets at the lower edge are used to connect the plate to the front
moulding using two 2 mm hexagon grub screws.
