The Processing Unit
The Processing Unit, incorporating Nucleus SmartSound
™
technology,
is the brain of your processor, where sound signals are encoded for
transmission to the implant.
The Processing Unit is worn on the ear, with either the BTE
Controller (or Mini BTE Controller) or the shoe that connects it to
the Bodyworn Controller or Babyworn wearing option.
Both the coil cable and Bodyworn Cable are available in a variety of
lengths and colours. The Babyworn Cable is available in one length
but comes in a variety of colours.
The controller
In addition to housing the batteries, controllers have:
•
A display that indicates the operations occurring
•
Buttons that operate your processor
The BTE Controller contains three 675 disposable batteries or the
BTE rechargeable battery, and is normally attached to the Processing
Unit when worn.
The Mini BTE Controller contains two 675 disposable batteries and is
always attached to the Processing Unit when worn.
The Bodyworn Controller can be worn in a pouch on a harness or
attached to a belt. It can also be held in a pocket or secured to your
clothing.
The Babyworn wearing option allows the BTE Controller to be
separated from the Processing Unit and worn on your child’s clothing.
�
Although very unlikely, the Bodyworn Controller may overheat
and malfunction. To prevent discomfort and/or irritation to
the skin, infants and young children should always wear the
Bodyworn Controller in a pouch provided by Cochlear Limited.
If an infant or young child cries without reason or exhibits other
behaviours consistent with discomfort, parents and caretakers
should check the Bodyworn Controller and verify that it has
not overheated.
