Figure 2: Decasing the Transceiver
c) With the transceiver held face downwards, squeeze the sides of the case at point
`C'. At the same time hook the first and second fingers of the other hand round the
lip at the end of the case back, and then peel back. The case back will unclip itself
from that end.
d) Squeeze the case sides with thumb and fore finger at points `D'. If the case back
does not come free, squeeze the case at either side of the speaker aperture: the
case back will now hinge clear.
e) Undo the two screws securing the Radio Board and gently prise the board out from
the battery end with a blunt instrument.
f) Undo the six screws securing the Decoder Board to the case front. Take care not
to damage the loudspeaker wires when lifting the Decoder Board away. Note that
on early models the two screws nearest the Display Module are longer.
g) To remove the Decoder Board completely, release the loudspeaker from its retainer
by undoing one or more of the screws securing the retainer to the case front. Lift
out the Decoder Board with the loudspeaker.
h) If required, the Display module may be disconnected by unsoldering its ribbon cable
from the Decoder Board. Likewise the loudspeaker may be disconnected by
unsoldering its wires from the Decoder Board.
