Introduction
The Cochlear Nucleus CR220 Intraoperative Remote Assistant is a hand-
held remote control that enables a clinician to perform impedance and
AutoNRT™ tests on a Cochlear implant in the operating theatre.
The intra-operative remote assistant is compatible with the CP810
processor. It does not support bilateral functionality or accessories.
The purpose of this user manual is to guide clinicians through the
functions and uses of the CR220 intraoperative remote.
It is strongly advised that you familiarise yourself with the intraoperative
remote assistant well in advance of your fi rst scheduled surgery.
The sound processor and the remote assistant are not sterilised

Hold the remote assistant in the palm of your hand. Keep it within 2
metres (about six feet) of the sound processor (about six feet) of each

Charge the remote assistant battery
It is recommended to fully charge the remote assistant battery before
using the remote assistant for the fi rst time. It may take approximately
2 to 4 hours to fully charge a completely empty battery. A fully charged
battery should provide you with enough battery life to last a full surgery.
However, battery life varies depending on amount of usage.

Technical and legal information
Technical information
The remote assistant wireless communication link operates in the 2.4
GHz ISM band using GFSK (Gaussian Frequency Shift Keying) on 10
channels. The link uses a proprietary bi-directional communication
protocol and operates over a distance of up to 2m from the
CP810 series processor. When interference is present, the wireless
communication link switches between the 10 channels to fi nd a
channel where the interference least affects the operation of the link.
The remote assistant indicates via its display when the processor is not
within operating distance, and when the link has been interrupted due
to interference.
