WARNINGS AND PRECAUTIONS
WARNING
Refers to a hazardous situation that could result in death or serious injury if not avoided.
•Information on how the hazardous situation is avoided.
CAUTION
Refers to a hazardous situation that could result in minor or moderate injury or material damage
if not avoided.
•Information on how the hazardous situation is avoided.
WARNING
System components immersed or in contact with liquids may cause electrical shock.
•The Battery Pack is classified as an IP0 –ordinary degree of protection against ingress of water
according to IEC 529. The Battery Pack is not water proof. Prevent detergent solution or cold
sterilization agents from seeping into the electronics of the system.
Battery pack stored by plugging into the charging source reduces the battery life.
•Do not store the battery pack plugged in to the charging source.
Cleaning the device while it is connected to an EMU40EX amplifier or a charger could lead to
electric shock to the user.
•Do not clean the device when it is connected to an amplifier or a charger.
CAUTION
Unauthorized use of the battery pack can affect function and performance.
•Use with EMU40EX Breakout Box only.
Unauthorized modification of the battery pack can affect function and performance.
•Do not attempt to disassemble the Battery Pack. It does not have any serviceable parts.

CAUTION
Disposal of battery pack in the fire could lead to explosion.
•Do not dispose the Battery Pack by burning.
Device used at higher temperature than the intended leads to functional failure.
•Do not use the Battery pack under ambient temperature higher than +40C°.
Device exposed at higher temperature than the intended leads to functional failure.
•Do not expose the Battery Pack to temperatures higher than +60C°. It may cause fire or
permanent damage to the Li-ion battery.
Battery Pack completely discharged for a long time before storing could lead to failure of
battery.
•Do not keep the Battery Pack completely discharged for a long time. Optimal is to pre-charge it to
50~75% before storage (i.e. charge it for about 2 hours).
Device dropped or damaged in transit/use could lead to loss of function or delayed diagnosis.
•Inspect the device prior to each use and do not use if damaged.
Modifications to the device can affect function and performance.
•Do not modify device or use unauthorized accessories supplies or components.

INTENDED USE
The EMU40EX Battery Pack is intended for use with EMU40EX Breakout Box only, which is used in
combination with NeuroWorks®/SleepWorks™ software to allow a qualified medical practitioner trained in
electroencephalography or polysomnography to acquire, display, archive, review, and analyze
physiological signals. It can be used with patients of all ages, but it is not designed for fetal use.
INTENDED USERS AND PATIENT TARGET GROUP
The intended users of the EMU40EX battery pack are trained medical professionals or someone
instructed by a trained medical professional. At minimum, it is expected that the user has a basic
understanding of clinical EEG and PSG, conducting an EEG or PSG study, proficiency with computers
and modern operating conventions. The user is typically trained on the use of the
NeuroWorks/SleepWorks software to operate the system or conduct a study acquisition using the
EMU40EX amplifier.
CLINICAL BENEFITS
The EMU40EX batter pack extends the period that a patient may be in an ambulatory position or not
physically connected to an amplifier base through a cable to facilitate the continuous recording of a
patient’s physiological parameters.
CONTRAINDICATIONS AND SIDE EFFECTS
There are no known contraindications or side effects for procedures performed with the EMU40EX battery
pack.
CHARGING THE BATTERY PACK
•Connect the Battery Pack (Fig.1) to USB Power Adapter (Fig.2) or to a computer USB port using USB
Power Cable (Fig.3).
•Check that “Charging” yellow light is on. If yellow light is off, it means, that charger does not detect
sufficient power and will not charge properly. Check cable connections and try again.
•Leave the Battery connected to the power source until continuous yellow light (“Charging”) is turned
off and continuous green light (“Battery”) is turned on.
•Unplug USB Power Cable (Fig.4) from the Battery Pack. All lights should be off. The Battery Pack is
now ready to use.
NOTE: Complete charging cycle may take about 3½ hours when using USB Power Adapter (Fig.2) and
5~6 hours when using PC USB port. Charging the Battery Pack from USB port is not recommended
due to longer charging time.

USING THE EMU40EX HEADBOX WITH THE BATTERY
PACK
•Connect Battery Pack (Fig.1) to EMU40EX Breakout Box using EMU40EX power cable (Fig.4).
•Green light (“Battery”) will keep flashing as long as the battery is at least 20% full.
•When the Battery Pack is discharged to less than 20% of its capacity, flashing light “Battery” changes
its color to RED. This is a warning for you to complete the study or to change the power source in less
than 1 hour.
•Even after the Battery Pack is discharged and all lights are off, there may still be some power available
stored in the internal battery of the EMU40EX Breakout Box.
USEFUL TIPS
•In order to check condition of the battery simply connect the EMU40EX Power Cable (Fig.4). There is
no need to connect the headbox for this check. Three cases are possible:
1. “Battery” LED is off the battery is completely discharged.
2. “Battery” LED is flashing GREEN the battery is more than 20% full.
3. “Battery” LED is flashing RED the battery is less than 20% full.
•Please do not leave EMU40EX Power Cable (Fig.4) plugged if you do not intend to use the Battery
Pack for a long time. When the EMU40EX Power Cable is unplugged, the Battery Pack automatically
enters low-power standby mode prolonging battery life.
•All lithium batteries are “perishable products”. Their life expectancy is limited to 500 charge-discharge
cycles or 5 years due to chemical degradation of active electrodes. You may see very slow degradation
of the lithium cell performance even if it is not used.
•Lithium battery will last much longer when using more shallow charge-discharge cycles rather than
full-charge —full-discharge cycles. Battery life in charge-discharge cycles is specified for the latter
(worst) case. Use fresh or fully charged batteries before beginning a study.
•If you are not going to use Battery Pack for a few weeks or longer, please pre-charge it approximately
to 50~75%. This is optimal for long-term storage. Do not store a totally discharged battery as this may
render the battery pack inoperable.
•Do not continuously leave the battery pack charging. Overcharged cell leads to faster electrode
degradation.
•If you need longer continuous operation two (or more) batteries can be used to prolong disconnected
operation of EMU40EX headbox. This is limited by the memory storage capacity of the EMU40EX
headbox.

lint-free cloth dampened with tap water to wipe the surface area.
•Dry using a lint-free cloth and air dry.
•Do not allow any liquid or cleaning solutions to come into contact with the LED electronics, contacts, or
connectors.
•Do not use alcohol-based or harsh abrasive cleaners.

DISPOSAL 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.
