1. SAFETY INFORMATION
At ZIBRIO we are very safety conscious, and we design and
manufacture products with the safety of you, our valued
customer, at the forefront. We ask that you adhere to the following
precautions when using your Stability Pro scale.
WARNING: No modication of this equipment is allowed. Do not
use with accessories, detachable parts, or materials not described in
this manual.
1.1 Limitations
• e Stability Pro scale is not intended to diagnose or treat any
illness or condition. While the Stability Pro scale measures
balance, poor balance in itself is not a disease and can be caused
by variety of conditions. If you suspect an underlying medical
condition that is aecting someone’s balance, consult a doctor;
only a doctor can diagnose such a condition.
• Contraindications: e Stability Pro scale is not intended for
use by individuals who are unable to stand unassisted for at
least 60 seconds. e Stability Pro scale may not assess balance
accurately in the following populations: individuals with
vestibular disorders, tremors, or attention and memory issues.
• An operator should always spot patients as they mount and
dismount the scale, and should remain in close proximity,
spotting them, throughout the duration of the balance test.
• e Stability Pro scale cannot be used to gauge intoxication
level due to alcohol or other substances. Getting a high
balance score is not an indication of tness for driving or other
activities.
• e Stability Pro scale is intended for use in professional health
care, home health, or professional tness settings.
• e Stability Pro scale should be used in a distraction-free
environment for best results.
3
• Maximum weight limit of 350 lbs.
1.2 Care and Use
• Must be used on a hard, level oor. Balance scores and weights
will likely be inaccurate if the scale is used on a carpeted oor
or an uneven tile oor.
• Should not get wet. Do not immerse in water. Be sure the
surrounding oor and the surface of the scale are dry to avoid
slipping when using the scale.
• If cleaning is needed, clean top glass surface with glass cleaner.
Plastic surfaces may be wiped with a cloth dampened with tap
water. Disinfectants suitable for glass or plastic surfaces may be
used on the respective surfaces.
• Should be inspected for damage prior to use. Inconsistent
weight or balance readings could result if the scale is damaged.
Check for cracks in the glass or plastic surfaces. Check to
ensure that the battery cover is rmly attached. Check to make
sure all 4 foot pads are present and undamaged. Inspect power
adapter for loose parts, fraying, or other damage.
• Should not be used if the glass top is cracked, as injury may
occur.
• Should not be dropped, as this may lead to personal injury or
damage to the device.
• Avoid stepping on the edge of the scale to minimize likelihood
of tipping.
• Verify that the scale display is working correctly by observing
the Power On Self Test. When the scale is rst powered on,
either through plugging in or installation of new batteries, each
segment of the number display will light up in sequence and the
scale will beep three times. If any of these components of the
display does not light up, the display may be faulty, which could
lead to inaccurate weight or balance score readings.
• Changing batteries is the only service or maintenance task that
users may perform. Do not perform service or maintenance
4
while in use with a patient.
• Avoid exposing the scale tomagnetic elds, electromagnetic
elds, external electrical inuences, electrostatic discharge,
pressure or variations in pressure, acceleration, or thermal
ignition sources, as these conditions may damage the product.
• In the event that you observe unexpected behavior of the scale,
follow the instructions listed in section 10, “Error Codes and
Troubleshooting.”

2. ABOUT THE STABILITY PRO SCALE AND
ZIBRIO BALANCE TEST
e Stability Pro scale measures postural stability through the
ZIBRIO Balance Test, which is a 60 second test with a two-legged,
open-eyed stance. Balance is measured in Brios, on a scale from
1 to 10. 10 Brios represents the best possible balance across the
human population. 1-3 Brios is associated with an increased risk of
falling in adults ages 65 and up. e scale also measures weight.
Score of 7 – 10: low risk of falling (green zone)
Score of 4 – 6: medium risk of falling (yellow zone)
Score of 1 – 3: increased risk of falling (red zone)
In a ZIBRIO study of over 300 adults, people who scored between
1 to 3 were three times more likely to experience a fall in the next
year compared to people who scored between 7 and 10. Balance can
change from one day to the next. Having poor balance can result
from a variety of causes, and this device is not intended to diagnose
or treat any disease or condition. Physicians should consult
ZIBRIO Clinical Decision Support soware (otherwhise known as
BalanceCare). If you are not a physician, please refer your patient/
client to an appropriate primary care doctor.
2.1 Intended Use
e Stability Pro scale is intended to quantify balance and weight in
adults. It is intended for professional use. It is not intended for self
testing, and an operator should remain with the user to spot them
as they mount and dismount the scale and to spot them for the
duration of the test.
e weighing function of the scale may be used by anyone weighing
at least 20 lbs. However, the balance measurement algorithm is not
6
optimized for children, and will not give an accurate measurement
of a child’s balance ability. It is meant to assess balance in adults
ages 18 and older and weighing at least 50 lbs. It may not assess
balance accurately in the following populations: individuals with
vestibular disorders, tremors, or attention and memory issues.
2.2 Patient Contact
e glass surface of the Stability Pro scale is the applied part, which
will make contact with the patient. e patient should stand on
the glass surface. e patient does not need to come in contact
with any other parts of the device. e patient does not need to
remove their shoes before standing on the device, although patients
wearing high heeled shoes or other shoes that interfere signicantly
with comfortable standing may wish to do so. In the event that
patients do remove their shoes, it is not necessary to remove
socks. e Stability Pro may also be used barefoot if desired. If the
scale is being used with shoes on, the scale does not need to be
cleaned in between uses by dierent patients. If the scale is being
used barefoot, clean the glass surface of the scale between uses by
dierent patients, following instructions in section 1.2. e scale
does not need to be cleaned between uses with the same patient.

4. SCALE POWER OPTIONS
4.1 Power Adapter
To power the Stability Pro scale via a wall outlet, plug the included
power adapter into the port on the le side of the front edge of the
scale. en plug into a wall outlet.
4.2 Battery Power
To operate the Stability Pro scale with batteries, open the battery
compartment and add 6 new AA batteries (not included). Use a
Phillips head screwdriver to remove the battery cover on the back
of the scale. e power adapter may still be used when batteries
are inserted in the scale. When the scale is plugged in, the power
adapter will override the battery power option. When operating on
battery power, the batteries can be expected to power the scale for
a typical service life of 1 year, or for at least 480 uses to measure the
balance and weight of a single patient, whichever comes rst.
If at any time your scale will not power on, the batteries may be
dead. Replace dead batteries only with 6 new AA batteries. Only
use batteries that are UL/IEC approved. Do not use rechargeable
batteries - they will not be recharged when the unit is plugged in.

5. INITIAL SETUP
5.1 Powering on the Scale
• Refer to section 4 for explanation of how to power the scale via
power cord or batteries.
• To turn on the scale, place it on a at surface and step or press
on it.
5.2 Where to Put the Scale
• Place scale on a level, hard oor.
• Place the scale at least 1.5 feet from a wall, facing the wall, for
a balance test. Some users who place the scale closer to wall
report feeling visual discomfort during the balance test.
• Do not stack the scale on top of other equipment or place
in close proximity to other electrical equipment. Portable
RF communication equipment that include antennas can
aect medical electrical equipment, and should be placed no
closer than 12 inches (30 cm) to any part of the Stability Pro,
including cables specied by the manufacturer.
• Do not position the scale in a location that makes it dicult to
unplug the power adapter.
• Some users feel more comfortable holding onto something for
support while stepping on and o the scale. If you place the
scale nearby to a piece of furniture, be aware that some users
may attempt to grab onto it to steady themselves, and ensure
that the furniture is secure enough for this purpose. is may
be acceptable if the furniture is permanently attached to the
wall, i.e. a cabinet, but if it is a tip prone piece of furniture,
we recommend placing the scale out of reach of these items.
If your users are in need of a helping hand, we recommend
spotting them at all times as they get on and o the scale, and/
or installing a permanent grab bar next to the scale.
• Note that users cannot hang onto anything during the test, as
10
this will lead to an inaccurate score.
• Be sure to have a visual focal point on the wall for users to look
at during the balance test. If testing in front of a blank wall, you
can attach a printout of the Balance Test Instructions Poster
onto the wall at eye level. Some users have reported feeling
dizzy if testing in front of a completely blank wall.
• Some users who use walkers feel more comfortable rolling their
walker over the scale to assist their mount and dismount. ese
users should not hold onto the walker during the balance test,
as this will lead to an inaccurate score.
• Place the scale in an area free from visual and auditory
distractions for best results.

6. USING THE STABILITY PRO SCALE
6.1 Weight Measurement
1) If you have moved the scale between uses, it is important
to zero the scale to get an accurate weight reading. Zero the
scale by pressing on it for 2 seconds and then releasing. You
should hear a beep and see ‘- - -’ temporarily on the display as
conrmation that zeroing has occurred. e display will then
read ‘0.0.’
2) Have the user step onto the scale and stand still. Once the
weight has stabilized, the scale will display the user’s weight.
3) By default, the Stability Pro scale will display weight in pounds.
If desired, the scale display can be changed to kilograms
through the ZIBRIO Balance Coach mobile app, which
connects to the scale via Bluetooth. See section 8 to learn how
to do this.
6.2 Administering a Balance Test
1) If the scale was moved between uses, it is important to zero
the scale to get an accurate weight reading. Zero the scale by
pressing on it for 2 seconds and then releasing. You should hear
a beep and see “- - -“ as conrmation that zeroing has occurred.
en the scale will read “0.0”. If the scale was not moved since
the last use, skip this step.
2) Be sure that a visual focal point (i.e. the Balance Test
Instructions Poster) is mounted to the wall at eye level for the
user.
3) Go over the test instructions with the user:
a) To perform the balance test, you will need to stand as still as
you can on the scale for 1 minute.
b) Keep feet a comfortable width apart and your hands relaxed
by your sides. Do not move your hands or ngers during
the test. Breathe normally.
12
c) Keep your eyes open during the test, and look forward. Do
not look down or move your head during the test.
d) Do not talk or chew gum during the test.
4) Assist the user in stepping onto the scale. Users’ feet should be
a comfortable standing width apart. eir feet should not hang
over any edges of the scale, and should be fairly centered.
5) Have the user stand still on the scale, complying with the test
instructions. Aer a few seconds, the scale will beep and start
the balance test, which lasts for 1 minute. Continue to supervise
the user throughout the duration of the test to ensure that
they are complying with the testing instructions. If the user is
13
unsteady, spot them throughout the test. Remain out of eyesight
of the user so that your movements do not distract them during
the test. Stand directly behind them or behind them and to one
side.
6) At the end of the test, the scale will beep and the balance score
will be displayed on the scale (1-10). Aer the user steps o the
scale, the balance score will remain displayed for 10 seconds or
until someone presses on the scale to zero it again.
7) If the user steps o the scale too early, makes erratic movements
during the test, or another error occurs, the scale will display
“Err” instead of a balance score. In this case, the test must be
retaken.

7. UNDERSTANDING BALANCE SCORES
1-3 (red) means high risk of falling today
4-6 (yellow) means moderate risk of falling
7-10 (green) means low risk of falling
Balance changes every day, and many systems aect it. e ZIBRIO
Stability Score is a snapshot of a person’s balance right now. Do not
be alarmed if a score varies by a few points from one test to another,
this is normal. Many dierent factors aect a person’s balance score.
Refer to the ZIBRIO clinical counseling materials to help a person
understand why they scored the way they did.
7.1 What if a balance score is lower than expected?
• First check that the scale is on a rm, level surface. Do not test
on carpet or uneven hard oor.
• Was it a good test? e user needs to stand as still as possible
for the entire test. If they moved their head, lied an arm to
scratch their nose, or talked, for example, these movements
change balance and can lower their score. If the user didn’t
stand still, try repeating the test to get a true measure of their
balance.
• Make sure testing is taking place in a well-lit room, and not
in front of a blank wall. Some users feel dizzy if they look at a
blank wall during the test. Provide a picture, poster, or a focal
point on the wall during the test instead. Make sure the scale is
at least 1.5 feet away from the wall, as standing too close to the
wall could make the user feel dizzy.
• Remember that balance changes every day. A bad night’s sleep
can make someone tired, and can lower their balance score by
multiple points. If someone is fatigued from a hard exercise
session, this might also lower their balance score.
• Remember that a score of “10” represents perfect balance, for
example, an Olympic athlete at peak performance might get a
15
score of 10.
7.2 What if someone’s balance score is dierent every time
they take the test?
• It is not unusual for balance to change from day to day, or even
throughout a single day. Remember that many factors inuence
balance, and those are always changing. Refer to the ZIBRIO
clinical counseling materials to understand why a person may
have scored the way they did today.
• Some people’s balance scores will uctuate by as many as 4
points from day to day. For these users, it may be most useful
to pay attention to the fall risk category/color rather than the
number. For example, if their score uctuates between 4 and 6,
they are staying in the yellow category.
