Battery Warnings and Cautions
The PowerShell comes with a removable Lithium Ion Battery. Care-
ful attention must be paid to the warnings and cautions described
below relating to the Battery. Misusing the Battery may cause the
Battery to get hot, rupture, ignite and cause serious injury.
WARNINGS:
•Do not place the Battery in fire or heat the Battery.
• Do not install the Battery backwards so that the polarity is
reversed.
• Do not connect the positive terminal and the negative
terminal of the Battery to each other with any metal object
(such as wire).
• Do not carry or store the Battery together with necklaces,
hairpins, or other metal objects.
• Do not pierce the Battery with nails, strike the Battery with
a hammer, step on the Battery or otherwise subject it to
strong impacts or shocks.
• Do not solder onto the Battery.
• Do not expose the Battery to water or salt water, or allow
the Battery to get wet.
• Do not disassemble or modify the Battery. The Battery
contains safety and protection devices which, if damaged,
may cause the Battery to generate heat, rupture or ignite.
• Do not place the Battery on or near fires, stoves or other
high-temperature locations. Do not place the Battery in
direct sunlight, or use or store the Battery inside cars in
hot weather. Doing so may cause the Battery to generate
heat, rupture or ignite. Using the Battery in this manner
may also result in a loss of performance and a shortened life
expectancy.
• Immediately discontinue use of the Battery if, while using,
charging or storing the Battery, the Battery emits an
unusual smell, feels hot, changes color, changes shape or

appears abnormal in any other way. Contact the Breas
Medical Service Center at 1-855-436-8724 if any of these
problems are observed.
• Do not place the Battery in microwave ovens, high-
pressure containers, or on induction cookware.
• In the event that the Battery leaks and the fluid gets
into one’s eye, do not rub the eye. Rinse well with water
and immediately seek medical care. If left untreated the
battery fluid could cause damage to the eye.
• Only charge the Battery with the supplied Breas Medical
PowerShell and the supplied Breas Medical Power
Supply. Do not use any other removeable battery
charger, AC adapter, or other device to charge the
Battery.
• Do not attach the Battery directly to a vehicle cigarette
lighter or to the Power Supply plug.
• Do not continue charging the Battery if it does not
recharge within the specified charging time. Doing so
may cause the Battery to become hot, rupture or ignite.
• Remove the Battery from the PowerShell if the Z2 is not
likely to be used for some time. Do not use the Battery
to power any device other than the Z2.
• Only use or charge the Battery within the operating
temperature, humidity and altitude conditions specified
in the Technical Specifications section of this User
Guide.
• Only store or transport the Battery within the storage
and transport temperature and humidity conditions
specified in the Technical Specifications section of this
User Guide.
CAUTION:
• When the Battery is worn out, insulate the terminals
with adhesive tape or similar materials before disposal.

PowerShell Getting Started Guide

1. Slide the battery into the lower
bay of the PowerShell until you hear
the shuttle click indicating the bat-
tery has locked into place.
NOTE: The Battery can
be removed from the
PowerShell by pressing the
two blue buttons on the
Battery Shuttle and sliding
the Battery out.
2. Slide the Z2 all the way into the
upper bay of the PowerShell. You
will hear the Z2 click indicating that
it has locked into place. The Z2 will
power on in standby mode. The
display will read .
CAUTION: Insert the
Z2 carefully ensuring the
power barrel connector
slides into the power input
on the Z2.
Instructions for Use
NOTE: The Z2 can be removed from the PowerShell
by pressing the two [ ] symbols on the sides of the
PowerShell and sliding the Z2 out.
NOTE: Remove the Battery from the PowerShell when
the Z2 is not in use, unless the Power Supply is plugged
into the PowerShell to charge the Battery. Otherwise
the Z2 and PowerShell will drain the battery completely
within 2-3 days.

3. Connect one end of the CPAP
tube to the round end of the tube
adapter. Insert the other end of the
tube adapter into the outlet of the
Z2 as shown.
Connect the other end of the CPAP
tube to the mask. Ensure all con-
nections are tight to avoid air leaks.
If you are using a Qtube and HME,
the order of pieces are as follows:
PowerShell, tube adapter, 8”tube,
Qtube, 4’ tube, HME, mask.
4. Push the start/stop button ( )
to initiate therapy. Push this button
a second time to stop therapy.
Alternatively, the Z2 Auto fea-
tures an Auto On/O which starts
therapy when you place the mask
on your face and start to breathe
and stops therapy when the mask
is removed.
NOTE: It is recommended
that you fully charge the
battery prior to each use.
Instructions on how to
charge the battery follow
in this guide.

Charging the Battery
1. With both the Z2 and the Bat-
tery fully inserted into the Power-
Shell, plug the Power Supply into
the PowerShell as shown and into
a power outlet.
2. Ensure the Z2 is in standby mode
(display reads 0.0). The Battery
will not charge unless the Z2 is in
standby mode. The Battery status
indicator on the Z2 will flash when
the Battery is charging. The number
of solid bars indicates the current
level of charge. The battery status
indicator will stop flashing when the
Battery is fully charged.
WARNING: Only charge the Battery with the supplied
Breas Medical PowerShell and the supplied Breas Medical
Power Supply. Do not use any other battery charger, AC
adapter, or other device to charge the Battery.
CAUTION: Make sure your Battery is fully charged
before commencing CPAP therapy using the PowerShell.
The battery life of a fully charged Extended Life Battery in
the PowerShell is typically 8.9 hours or longer, after which
treatment will terminate.

Trouble Shooting Tips
Battery is not charging
1. Disconnect the Z2 from the Battery and the power
supply.
2. If you squeeze the arrows on the sides of the
PowerShell, you should feel the Z2 release.
3. Reassemble the Z2 and the battery to the PowerShell
and to the power supply. When reassembling, make
sure you hear the components click together and
see that the DC plug (silver cylinder in the bottom of
PowerShell) goes into the hole in the Z2.
4. Make sure to fully charge the Battery for 12 hours
after use.
5. The battery icon on the Z2 screen will stop flashing
and all bars will be solid.
NOTE: Battery icon starts showing 4 bars at 90% charge.
Wait for battery icon on Z2 LCD screen to stop flashing.
Number of Solid Bars Charge Remaining
1 10-35%
2 35-63%
3 63-90%
4 90-100%
Typically it will take 12 hours to fully charge the battery. After a few
minutes, the back light of the display will turn off. This is to con-
serve power. It does not indicate that the battery is fully charged.
NOTE: The PowerShell will not charge the battery at the
same time as you are using your Z2 for treatment.

Battery Losing Its Charge Between Trips
If you are not traveling on a regular basis, your battery may dis-
charge completely between trips. It is recommended that every
few weeks you fully charge your battery to maintain a charge on
it. When it is fully charged, remove from PowerShell and store it
separately so it does not drain the battery charge.
To Release Z2 from PowerShell
Press and hold the 2 blue arrow
buttons at the bottom of the grey
sleeve of the PowerShell while
simultaneously pulling up on the
Z2.
To Release Overnight Battery
from PowerShell
Press and hold the 2 blue buttons
on the white cap of the battery, and with even pressure, pull up at
the same time.
Using the DC Mobile Adapter
Your PowerShell Battery can be charged with the DC Mobile Adapt-
er using most automobile charging systems. The amount of time
will vary, depending on the voltage delivered by the car battery.
Some cars chargers only work while the car is running. Ideally the
Mobile Adapter would be used while the car was being driven
during the day, so the battery will be charged for the night.
We cannot guarantee the mobile adapter will function with all cars.
NOTE: Your DC Mobile Adapter cannot be used to run your Z2.

Minimum Voltage Needed to Charge your Z2
12 volts.
Battery Life
The battery life varies depending on the altitude and pressure set-
ting of the unit. Higher altitudes and higher pressures will use more
battery life.
Temperature can also be a factor. Colder weather will use more
battery life. The battery is designed to be used in temperatures
between 41˚ F and 95˚ F.
Do not charge the battery in temperatures above 80˚F.
