OPERATING INSTRUCTIONS
The LifeChoice Activox POC is recommended and designed to be operated
and stored in its carry case at all times. To configure the carry case as a
backpack, please reference the Carry Case Configuration Instructions.
FOLLOW THESE STEPS BEFORE FIRST USE:
1. Charge the POC before initial use. The Pro Model can take up
to 4.5 hours to fully charge and the Sport Model can take up to 3
hours. Begin charging by connecting the AC Adapter to the unit
and charger end to an electrical outlet.
2. Verify that the Battery Check LED labeled “INT” is solid green and the
Power LED is flashing green. This indicates that the system recognizes
the external power source and is charging the Internal Battery.
If an external battery was purchased, connect it to the External Battery
Port. By design, the External Battery will begin charging after the
Internal Battery has reached a full charge. It can take up to 3 hours to
fully charge the External Battery.
CAUTION: Never use an external battery that is not authorized by
Inova Labs Inc. DO NOT dismantle, open or shred secondary cells
or batteries. DO NOT expose cells or batteries to heat or fire. Avoid
storage in direct sunlight.
3. Connect the nasal cannula securely to the POC cannula nozzle
fitting.
POWERING THE LIFECHOICE ACTIVOX POC
The POC can be powered in four different ways: (1) Internal Battery,
(2) AC Adapter/Charger, (3) DC Adapter/Charger, (4) External
Battery (optional, sold separately from the Standard Package).
The rechargeable batteries are maintenance-free and can only be
purchased at the factory or through an authorized repair facility.
1. Internal Battery: A rechargeable internal battery is located within
each POC unit. (Reference Battery Life Timetable as battery life will
vary depending upon model,
breath rate and Pulse Setting.)
When the POC is being powered
from the Internal Battery, the
Battery Check LED labeled “INT
will slowly flash.Pushing the Battery
Check Button will display the
charge level of the Internal Battery.
If not connected to the AC or DC
Adapter/Charger, the Internal
Battery will slowly discharge over time even when not in use. Always
check the battery level prior to use to ensure adequate charge level.

2. ACAdapter/Charger:AnACAdapter/Chargerallows the POC to be powered
from a standard 100-240 VAC, 50/60 Hz
outlet. When the unit is operated from an AC
Adapter/Charger, power from the AC outlet
powers the unit and recharges the internal
and/or External Battery. (See Battery
Charging section for details.)
Using an AC Adapter/Charger that is not
specified by Inova Labs with the POC
may damage the unit and will void all
warranties.
3. DC Adapter/Charger: A DC Adapter/Charger can be connected from
the POC unit to a vehicle’s (car, boat, motor
home, etc.) standard 12 VDC outlet. When
the system is connected to the DC outlet,
power from the vehicle battery powers the
POC unit and recharges the Internal and/
or External Battery. (See Battery Charging
section for details.)
NOTE: The 12 VDC outlets in some pre-2000 model cars will not provide
sufficient current to operate the POC and charge the battery at the same
time. Verify that a DC outlet can provide at least 10 amps at 12 VDC. Car
auxiliary power varies significantly; therefore, the rate of charging will
vary. It is recommended that the vehicle be turned on before plugging
the DC Adapter/Charger into the POC.
4. External Battery: To power the POC from an external battery, connect
the External Battery to the External Battery Port. A
fully charged external battery will supply power to the
POC for up to three hours. (Reference Battery Life
Timetable as battery life will vary depending upon
model, breath rate and Pulse Setting.)
When the POC is being powered from the External
Battery, the Battery Check LED labeled “EXT”
will be slowly flashing. Pushing the Battery Check
Button will display the charge level of the External
Battery.
INTERNAL BATTERY CHARGING
1. Connect the unit to either an AC or DC Adapter and corresponding
charger to a suitable outlet.
2. With the unit powered off, verify that the INT Battery Check LED is solid
green and the Power LED is flashing green. This indicates that an external
power source is recognized and the battery is charging.

reaches a full 100 percent charge, the INT LED will turn off.
5. It is recommended to recharge the Internal Battery, even if only
partially depleted as often as possible. The Internal Battery cannot
be overcharged, so it is okay to leave it plugged in via an AC or DC
Adapter/Charger continuously.
EXTERNAL BATTERY CHARGING
1. Connect the External Battery to the External Battery Port on the
POC. Then connect the unit to either an AC or DC Adapter and
corresponding charger to a suitable outlet. To prolong battery life
and maintain communication with the POC, it is recommended to
charge the External Battery when you charge the POC’s Internal
Battery.
2. Verify that the Battery Check LED labeled “EXT” is solid green and
the Power LED is flashing green.
This indicates that an external power
source is recognized and the battery
is charging.
NOTE: By design, the Internal
Battery will charge first. That means
that the External Battery will not start
charging until the Internal Battery
reaches a 100 percent charge level.
Use the INT and EXT Battery Check
LEDs to determine which batteries
are charging.
3. It takes up to 3 hours for a fully discharged External Battery to reach
a 100 percent charge level when plugged into the unit and an AC or
DC Adapter/Charger. Press the Battery Check button to check the
charging progress.
NOTE: By design, the External Battery will power the POC when
plugged in. Once the External Battery depletes, the unit will switch to
internal battery power. If both the Internal and External batteries are
fully discharged, it can take up to 7.5 hours to achieve a 100 percent
charge level in both batteries.
OPERATING
INSTRUCTIONS
continued

4. When the External Battery is fully charged, the EXT Battery Check LED
will turn off.
NOTE: The charge indicator will show 4 solid green lights when the
battery has a charge level of 96 percent or more. When the battery
reaches a full 100 percent charge, the EXT LED will turn off.
In the event the power supply is interrupted to the POC when the AC or DC
Adapter/Charger is connected, a two-second audible alarm will sound and
the compressors will transition from external to internal power. During this
transition, you may hear the compressors momentarily pause. No action
is required as the system will automatically transition to internal power and
resume operation.
NOTE: If the POC is powered off and either the AC or DC Adapter/Charger
is connected and charging is complete, the internal fans may continue to
operate for an additional period of time until the temperature inside the unit
is sufficiently cooled.
REPRESSURIZATION
If the unit has not been used for a period of one or more days, it will
automatically re-pressurize itself. During this time, you may hear the
compressors running for a few seconds.

used will illuminate.
CAUTION: DO NOT place the cannula into nasal passages until the
POC has fully powered on. Breathing through the cannula during
start-up may prevent the system from powering on.
4. There are 2 inhalation sensitivity
modes on the control panel:
Active-High and Sleep-Low which
automatically adjust based on oxygen
demand (e.g. breathing pattern)
requirements. No action is required
to start the delivery of oxygen.
14

15
5. Select a Pulse Setting of 1, 2, or 3 as prescribed by your doctor. The
device utilizes PULSE-WAVE™ Delivery which delivers oxygen
congruent with your inhalation rate. Because this type of delivery
is very gentle, you may not feel the pulse of oxygen. To verify that
oxygen is being delivered, reference the LED above your selected
Pulse Setting. This LED will flash every time a breath is detected
and a bolus of oxygen is delivered.
6. Place the nasal cannula in the nasal passages and breathe normally.
When the POC senses inhalation, oxygen is supplied through
the cannula. The duration and size of the pulse is dependent
upon the Pulse Setting selected.

ROUTINE CLEANING AND MAINTENANCE
The LifeChoice Activox POC was designed to minimize the amount of
routine maintenance that is required. The device does not have any
end-user repairable parts. Aside from the preventative maintenance
outlined below, all other maintenance required must be performed
by qualified personnel.
Fan Inlet Vent Cleaning: There is one inlet vent located on the right
side (facing the unit) of the POC. The carrying case for the unit has
mesh material corresponding to the location of the Fan Inlet Vent.
You should visually check the carrying case to ensure that there is no
buildup of lint, hair or other materials
that could obstruct the flow of air into
the unit’s fan inlet vent. Remove any
material buildup using a soft brush.
At least once a month inspect the
grille of the intake vent and if it appears
dirty, use a dry cotton swab (Q-Tip
or similar) to clean it. Never use
alcohol, solvents, or petroleum
distillates for cleaning.
Unit and Carrying Case Cleaning: If it is necessary to clean the unit
and/or carrying case, use only warm water and a mild liquid dish
detergent. Dampen a cloth in the solution and carefully wipe the
outside surfaces of the unit and/or carrying case.
CAUTION: DO NOT use alcohol, solvents, polishes or any oily
substances since they may be flammable.
Nasal Cannula Inspection: At least once a week, visually inspect the
nasal cannula. Make sure there are no kinks or obstructions. Replace
as needed with a standard 7 ft. (2 m) single lumen nasal cannula from
your local medical equipment supplier.
Reserve Oxygen Supply: Your equipment provider should provide
or suggest an alternative source of supplemental oxygen therapy in
case there is a mechanical failure or power outage.
Hour Meter: The Hour Meter function is for use by trained service
personnel only.
