Before squeezing the two halves of the
clamshell together to close it, check that
the entire length of the probe section
inside the clamshell is within the
channel and that the camera head (the
thicker end of the probe) is within both
semicircular sections of the top of the
housing comprising the probe’s exit port
(Fig. 2, Callout K). Finally, squeeze the
two halves of the clamshell together to
close it. The clamshell is not properly
closed until you hear the latches snap.
If you chose the longer probe length, you
will have to wrap a long section of probe
within two turns of the channel inside
the clamshell (see sequence of six
photos beginning below).
