Introduction
The Natus ErgoJust LTM and Natus ErgoJust ICU are ergonomic carts used with Natus
NeuroWorks/ SleepWorks devices and accessories to provide a complete portable workstation for
EEG applications.
The Natus ErgoJust LTM cart provides a portable workstation at the point of care in any hospital
room requiring EEG monitoring or testing. It is ideally designed for as a comprehensive solution
for long-term EEG monitoring (LTM). It features mounting brackets for Natus amplifier base units,
acquisition computer with NeuroWorks/SleepWorks software, a monitor, pan-tilt-zoom (PTZ) or
high-definition (HD PTZ) video camera options, IR light and microphone, Natus photic stimulator,
isolation transformer (ISO) or uninterruptible power supply (UPS) and basket(s) for clinical
supplies.
The Natus ErgoJust ICU cart is ideal for EEG monitoring applications in an Intensive Care Unit
(ICU). It offers the same features as the Natus ErgoJust LTM cart but utilizes an All-in-One
desktop acquisition computer, ideal for a smaller footprint, touchscreen operation in the ICU.
Natus ErgoJust LTM and ErgoJust ICU features and options include:
•Height adjustable work surface and
keyboard tray
•Adjustable and tilting monitor
•Sit-to-stand adjustment range
•Quick disconnect attachment for Natus
amplifier base units
•Computer with Natus Neuroworks/
SleepWorks software
•Standard, high-definition (HD) and full
high-definition 1080p (fHD) cameras
•Small footprint base
•4-wheel lockable casters

Using this manual
This manual describes the theory, features, set up, operation and maintenance of the Natus ErgoJust
LTM and Natus ErgoJust ICU cart. It also provides information on specifications and getting help.
When reviewing the procedures, we recommend you read the entire section first, before beginning
a sequence. Please follow the instructions carefully.
IMPORTANT: All Natus ErgoJust LTM and Natus ErgoJust ICU cart systems must be installed or
upgraded by a qualified and trained Natus technician or representative.
IMPORTANT: Do not attach any cables until all components have been mounted. Chapters 3 and
4 describe where to connect and how to route cables.
Some components may have been factory mounted and cabled on the cart. The cabling diagrams
include steps even for those cables that have been factory connected so you can confirm the
connections are secure.
We strongly recommend that you read the Warnings or Precautions section of this
manual before operating this cart system.
Intended use
The Natus ErgoJust LTM and Natus ErgoJust ICU carts are portable workstations that house all
Natus devices and accessories needed to conduct a video or non-video EEG study for routine
testing, long-term monitoring (LTM) and EEG monitoring in an intensive care unit (ICU).
Intended user
The ErgoJust LTM and ICU carts are intended to be used by trained medical professionals.

Safety summary
Warnings or
precautions
The following is an overview of Warnings pertaining to the Natus ErgoJust LTM and Natus
ErgoJust ICU system cart. Additional Warnings and Precautions are located in the various sections
of this User guide. Please read and understand the information in this User guide and any
accompanying documentation thoroughly before using the Natus ErgoJust LTM and Natus
ErgoJust ICU cart system.
The function or safety of the equipment could be impaired if it has been subjected to
unfavorable conditions in storage or in transit. If, at any time, function or safety is thought to
be impaired, the instrument should be taken out of operation and secured against unintended
use.
Disconnect all power sources from all system components before servicing.
Conductive parts of electrodes and their connectors are not to contact other conductive parts
and earth.
The Natus Neurology Incorporated system is NOT intended for use with High Frequency
Surgical Equipment.
To avoid possible safety hazards caused by the summation of leakage currents when several
system components are interconnected, other equipment connected to the system should be
powered by a Natus-approved isolation transformer (ISO) or Uninterruptible Power Supply
(UPS).
Connecting other medical equipment, such as a cardiac pacemaker or other electrical
stimulators, simultaneously to the same patient may constitute a safety hazard. The Natus
ErgoJust LTM system is not defibrillator proof. The Amplifier Base Unit (electrode input
device) should be disconnected before using a defibrillator.
The oximeter port is only rated for ESD (Electrostatic Discharge) immunity when the
oximeter is connected or if an oximeter port cover is in place. Either the oximeter or the
oximeter port cover should be connected to the port at all times when in use.
This product must be cleaned and checked periodically. Do not use a defective product. Parts
that are broken, missing, worn, or contaminated should be replaced immediately.
This product must not be altered without the prior written approval of Natus Neurology
Incorporated. The user of this product shall have the sole responsibility for any malfunction
that results from improper use, faulty maintenance, improper repair, unauthorized service,
or alteration by anyone other than Natus Neurology Incorporated or a Natus qualified
service representative.
The safety, reliability, and performance of this device can only be assured under the
following conditions:
•If the device has been used according to the accompanying operating instructions.
•If changes or repairs have been carried out by Natus Neurology Incorporated.
•If it is used in buildings having ground equalization wiring that complies with relevant
UL, CSA, IEC or other local standards and regulations.

Impact Hazard! Moving parts can crush and cut.
Minimize lift tension before removing mounted equipment. Failure to heed this warning may
result in serious personal injury or property damage.
1. Lower work surface to lowest position.
2. Turn the adjustment nut at top of the riser counterclockwise until it stops (may require
40-60 turns to minimize lift tension).
3. After removing or adding equipment, adjust lift tension to compensate for weight of new
load.
Do not load cart below minimum or above maximum weight capacities. Do not mount a
display larger than the recommended size. Failure to comply with this warning may result in
cart instability leading to equipment damage or personal injury.
NOTE: If the lift tension is not adjusted to the weight of the monitor, the monitor or work
surface may shift by itself. Adjust the lift tension so that the monitor and work surface
remains stationary.

Disposal at end of operating life instructions.
Natus is committed to meeting the requirements of the European Union WEEE (Waste Electrical
and Electronic Equipment) Regulations 2014. These regulations state that electrical and electronic
waste must be separately collected for the proper treatment and recovery to ensure that WEEE is
reused or recycled safely. In line with that commitment Natus may pass along the obligation for
take back and recycling to the end user, unless other arrangements have been made. Please contact
us for details on the collection and recovery systems available to you in your region at natus.com
Electrical and Electronic Equipment (EEE) contains materials, components and substances that
may be hazardous and present a risk to human health and the environment when WEEE is not
handled correctly. Therefore, end users also have a role to play in ensuring that WEEE is reused
and recycled safely. Users of electrical and electronic equipment must not discard WEEE together
with other wastes. Users must use the municipal collection schemes or the producer/importers take-
back obligation or licensed waste carriers to reduce adverse environmental impacts in connection
with disposal of waste electrical and electronic equipment and to increase opportunities for reuse,
recycling and recovery of waste electrical and electronic equipment.
Equipment marked with the below crossed-out wheeled bin is electrical and electronic equipment.
The crossed-out wheeled bin symbol indicates that waste electrical and electronic equipment
should not be discarded together with unseparated waste but must be collected separately.
