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 remote assistant is to be used for surgery only.
The sound processor and the remote assistant are not sterilised
and should be enclosed in sterile plastic bags during surgery.

Features of the remote assistant
How to hold and operate the remote
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
other. Operating it at a greater distance may cause increased delay
between the sound processor and the remote assistant response time or
loss of communication all together.

Getting started
Initial set-up
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.
Ensure that you only use battery charging equipment supplied by
Cochlear to charge the remote assistant battery.
Tools to charge the remote assistant battery
To charge the remote assistant battery, you will need:

The impedance test indicates the electrical status of the intra-cochlear
electrodes. It loops continuously through the 22 electrodes, displaying
which electrode is being tested, and the status of all electrodes already
tested.

AutoNRT test
Neural Response Telemetry (NRT) measures neural activity within
the cochlea in response to electrical stimulation from the implant.
An AutoNRT test provides a quick, non-invasive, objective measure of
peripheral neural function.

• Only use the intraoperative remote assistant while the recipient is
under anaesthetic.
• Do not use or store the device in dusty or dirty areas, extreme high
or cold temperatures (e.g. Do not store in direct sunlight, behind a
window or in a car for extended periods of time)
• Take care when placing the remote assistant in a bag or pocket
with other objects as the display may scratch. Commercially
available protective fi lms may be used to protect the remote
assistant display from scratches.
• Do not use alcohol, household cleaners or abrasive materials to
clean the remote assistant.
• Do not use any commercial or household appliance to dry the
remote assistant.
• Only use the CR200 Series Global Power Adaptor, the CP900
Series Global Power Adaptor (if using the CP900 Series Battery
Charger) or the CR200 Series Global charging kit when charging
your remote assistant from mains power.
• Do not bend or compress the display on the remote assistant.
• Do not use excessive force when connecting or disconnecting the
USB cable or when using the buttons on the keypad.
• Do not disassemble, deform or immerse in water. If the remote
assistant is not working, return it to your clinician. Warranty will be
void if opened.
• Do not use the remote assistant if it becomes unusually warm.
Inform your Cochlear representative immediately.

regulations.
• When charging the remote with a computer, ensure the computer
conforms to IEC 60950 standards.
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.
Specifi cations
Physical confi guration
The remote assistant comprises:
• Custom analogue and digital integrated circuits based on a micro-
processor design, with bi-directional wireless communication
capabilities.
• Push-buttons/keys and a slider for control of processor features
and its own system features.
• A display for indicating system status and activity.
• A speaker for sounding an audible alert.
• In-built coil sensor to check if the processor’s coil is receiving
sound signals from the processor and for pairing.
• On-board battery charging circuit.
• A temperature sensor for battery safety.
• A micro USB connector for charging the remote assistant and
updating the fi rmware.
Materials
The remote assistant housing, including non-metallic buttons/keys, is
made of polycarbonate.
