Physical configuration
The CP802 Sound Processor is a modular device, made of four parts: the
processing unit, battery module or battery pack, coil and coil cable. The
complete device sits behind the ear (when using the battery module)
during normal operation, with the coil placed over the implant.
The processing unit comprises:
• Two omni-directional microphones for receiving sound.
• Custom analogue and digital integrated circuits with digital signal
processing (DSP) and bi-directional wireless communication
capabilities.
• A dual-colour light emitting diode (indicator light) for visual
indication of processor function or processor problem.
• Two push-buttons to allow user control of key features.
• Custom 4-pin accessory connector for connection of accessories
(e.g. monitor earphones).
• Custom 4-pin coil connector for connection of the coil cable.
• A range of earhooks.
The batteries provide power to the processor. The following options are
available for powering the processor:
• Disposable batteries.
• Rechargeable batteries.
The coil transfers energy and data to the implant. It is connected to the
processing unit by the coil cable. The coil cable can be detached from
both the coil and the processing unit. It is connected to both the coil
and the processing unit by custom 4-pin connectors. The connection
forms a seal to prevent moisture access.
