Inc. or authorized bodies.
The operator must be trained to recognize
the difference between signal artifacts and
valid bio-signals caused by movements,
interference, or misplacement of sensors
or electrodes.
Inspect all cables before and after each use.
Discard cable if insulation is damaged or if
the cable or connectors are damaged in any
manner.
This manual provides an operational
summary for the Easy III system. It does
not provide clinical training. It is assumed
that the user has adequate clinical
training.
The proper use of this device, for its
intended use, can only be assured once all
instructions have been read and understood.
Contact Cadwell with Easy III operational
questions.
The system is not defibrillator proof.
Do not use the system in an MRI
environment.
The system is not designed to operate in
an explosive environment.
A possible loss of data can occur if acquiring
data on a machine that has a network data
folder.
Do not immerse the amplifier, remote
input box, power-communications
module, flash stimulator, and system
cables in liquid.
Do not use power strips with the system
unless they are connected downstream of an
isolation transformer.
The system is designed to be used with
one patient at a time. Do not connect
multiple patients to one amplifier.
Do not connect items which are not
specified as part of or for use with the Easy
III system.
Never place an isolation transformer on
the ground.
Do not exceed the medical isolation
transformer maximum load.
When attaching the Easy III system to a
patient, verify that the subject will not
become entangled in the wires. Do not
allow the electrode wires to wrap around
the patient's neck.
Do not use the isolation transformer to
power non-system components; it may
overload the transformer or defeat the
separation by providing additional leakage
sources.
Do not update Persyst software
components without Cadwell approval.
Do not exceed the medical isolation
transformer maximum load.
Do not plug non-medical electrical equipment in the patient environment directly into a wall
outlet. This may cause excessive leakage current in the patient environment.

When active/reference pairs 1A-Ref, etc. are used, their references cannot be
changed during review. Usually these channels are unlinked and are used to
monitor non-EEG signals such as ECG or respiration.
If an active/reference pair is used, the active electrode cannot be used in any other
channel. For example, 4A-Ref and 4a-C3 cannot exist in the same montage.
Montages used during a recording are permanently saved with the record,
although you may select another montage for viewing at any time during review.
Even if you change the montage while reviewing, you can still re-display the EEG
as originally recorded.
113
