Placement of the Insert Phone
WARNING!
Push the correctly sized eartip onto the earphone and then place the
insert phone securely into the patient’s ear. Be sure there is an eartip attached to
the insert phone before inserting into the patient’s ear. Inserting the insert phone
without an eartip could cause harm to the patient. When using the paired insert
phones, follow the manufacturer’s recommended procedure for eartip
preparation, placement, and insertion.
WARNING!
Insert eartips are single use only. Using disposable eartips ensures
sanitary conditions for each patient.
Placement of the Bone Vibrator
The bone vibrator may be placed on the promontory of the mastoid process or on
the forehead, whichever has been selected in the Config App or modified in the
Configure screen.
Placement of the High Frequency Transducer
Remove eyeglasses and earrings if possible and position the transducer directly
on the head of the patient. Place the rubber cushions so that the earphone
diaphragm is aimed directly at the opening into the ear canal. Adjust the
headband for a tight fit. If the cushions are not tight to the ears, the test result will
be false, especially at lower frequencies.
WARNING!
Do not connect or disconnect Earphones, Insert Phones, Bone
Vibrator, High Frequency Transducers or any other accessories while in contact
with the patient.
