Attaching Probe Tube
A clear probe tube must be applied to the probe head before an eartip
is applied. Insert a new probe tube into the probe head until it is fully
seated (Figure 4). A properly inserted probe tube will snap securely
into place when it is fully seated in the probe head. It is not necessary
to replace the probe tube with each ear tip; the tube is reusable as long
as the probe tube is clear. To remove a probe tube, grasp the tube and
pull gently away from the probe head with a slight twist.
Attaching Eartips
The Corti instrument comes with a box of disposable, single-use
eartips that fit a variety of ear canal sizes. The Corti probe must have
a probe tube applied (Figure 4) and an eartip attached (Figure 5)
before inserting it into an ear canal. The determination of the
appropriate eartip size should be made by persons with proper
training and experience. The eartip must seal the ear canal. The best
test results are obtained when the eartip is inserted deeply into the ear
canal instead of flush with the ear canal opening. Caution must be
taken, however, to ensure that the eartip does not extend too deeply
into the ear canal. Use only the eartips approved for use with the
instrument. The eartips are disposable and must be replaced after each
patient.
After selecting an eartip, push it onto the probe tube until it is flush
against the base of the probe tube (Figure 5). Twisting the eartip
slightly while pushing it onto the probe tube is recommended. Be sure
the eartip is fully seated on the probe. There should be no gaps
between the eartip and the collar of the probe head (Figure 6).
To remove the eartip, grasp the eartip gently at the base and twist it
while pulling it straight off the end of the probe tube.
NOTE
: Grasping the base of the eartip will prevent the probe tube
from being inadvertently pulled out of the probe head along with the
eartip.
NOTE:
If the probe tube becomes dirty or clogged, it must be
replaced. See the section Probe Tube Replacement on page 42 for
further information.
Probe Holder
It is strongly recommended to place the probe into the probe holder
when the Corti is not in use. This should be done while the Corti is
placed on a counter top or table, or when the Corti unit is resting in
the Corti cradle. Placing the probe into the holder will help to protect
the probe head.
Make sure the probe holder is towards the end of the probe cable at
the GSI wave logo / HDMI connector end. Gently push the probe
