Insert earphones with ear tips

The ear tip is a small silicone tip that is placed on the infant ear tip adapter that is attached to the tubing of
the insert earphones. The ear tip is inserted into the baby's ear canal.

Peel the EarCup attached to the red tubing from the backing card. Place it
around the baby's right ear with the adapter and tubing pointing toward the
top of the head. Press around the entire circumference of the EarCup to
ensure adhesion to the baby's skin.
Peel the EarCup attached to the blue tubing from the backing card. Place it
around the baby's left ear with the adapter and tubing pointing toward the
top of the head. Press around the entire circumference of the EarCup to
ensure adhesion to the baby's skin.
Place the insert earphone transducer boxes above or to the side of the
baby's head away from electrode leads to reduce electrical interference.
Do not insert the ear tip adapter into the baby's ear without an ear tip
attached.
Please note: When using insert earphones, you cannot use the same
transducer for testing both ears. Only use the red colored transducer for the
right ear and the blue transducer for the left ear.
Choose the appropriate size of ear tip based on your inspection of the size
of the baby's ear canals (Figure 8). The Sanibel green ear tip fits most
newborn ears. Other sizes are available for larger ear canals.
Place the ear tips onto the ear tip adapters at the end of the insert earphone
tubing.
Insert the ear tip attached to the red tubing into the baby's right ear. Do this
by pulling gently down and out on the baby's ear lobe to open up the ear
canal. Hold the adapter, aim and gently twist the ear tip into the ear canal.
The fit of the ear tip should be secure; not superficial. Release the earlobe.
Repeat this procedure for inserting the ear tip attached to the blue tubing
into the baby's left ear
If you find that it is difficult to keep both ear tips secure in the baby's ear
canals at the same time, you can choose to test one ear at a time. It is
important that you use the transducer with the red tubing for the right ear
and the transducer with the blue tubing for the left ear.
Place the insert earphone transducer boxes above or to the side of the
baby's head to reduce electrical interference (Figure 9).
