Does Libris perform a self-test?
Libris communicates events to the Libris platform and Monitoring Service Provider periodically
throughout the day, when a call is made, and when it is placed in the charger.
Libris does not perform a self-test, but the data received from Libris contains information about
the health of the device, including battery, temperature, signal strength, and sensor status.
Is there a portal for end users to monitor
The EverThere online portal enables family members and caregivers to be alerted, via SMS or
email, to Libris device events including when the button is pressed and when a fall is detected.
The portal also provides other detailed device information, including logs of the device location,
signal strength and battery level. You will be emailed an invitation to the portal where you can
register and set up your EverThere account.
Libris is currently designed to be used in conjunction with a monitoring service to respond to
your emergencies.
A portal is currently being tested that will allow users, family members and caregivers to monitor
the Libris device and be alerted to Libris events. Be sure to let your dealer and monitoring
service know that you are interested.
Can cell phones call Libris?
Libris is designed to accept inbound calls from a designated monitoring service. It is not
currently designed to accept inbound calls or SMS messages from a personal cell phone.
Does Libris emit radiation?
Yes, similar to cell phones, the Libris emits radiation when in use. Libris meets FCC Specific
Absorption Rate (SAR) standards and is certified.
For more information about the FCC's SAR standards, please go to
Does Libris have a moisture detection alarm?
Libris does not have a moisture detection alarm; however, it is rated as highly water-resistant and
designed to be worn in the shower or bath.
Libris is submersible up to 1 meter for 30 minutes (IP67).
What language is supported on Libris?
Libris audio prompts are currently supported in English, French and Spanish.
Currently the only language supported on the Libris audio prompts is English. Adding additional

Is my Libris waterproof? Can I wear it in the
shower or bath?
Libris comes in a durable highly water-resistant shell that's splash- and rain-resistant. It can
sustain immersion in one meter (39 inches) of water for up to 30 minutes. However, it's not
suitable for extended and continuous water submersion. For showering or bathing, we
recommend you wear Libris on your lanyard or set it on the edge of the shower or bath area, so
that it is within reach, but not in the direct path of water. Libris is rated IP67.
Can I change the lanyard?
It is recommended that you use the provided lanyard. The Libris lanyard is designed to get the
best results from Libris when worn correctly.
Can I use Libris outside the home?
Yes. With Libris, you are not confined to your home. It is designed to be mobile and will work
wherever there is adequate cellular coverage. Poor cellular coverage may result in the inability to
place a call, automatically detect a fall, and/or properly locate you automatically during an
emergency. Check with your monitoring service for known coverage limitations.
Can more than one person use Libris?
Libris is designed for a single user and adapts to your daily activity patterns. Plus, your personal
information will be linked to Libris, so your monitoring service will know it is you when called.
Can I wear Libris to bed?
Your Libris needs time to charge and it is recommended that you set Libris in the charger for at
least 4 hours while you are sleeping.
How long does it take to recharge the
From a low charge, it takes approximately 4 hours to recharge Libris to fully charged status.
Do I need to replace the battery in Libris?
No, Libris is equipped with a rechargeable battery. To charge your Libris, place Libris in the
charger every night for at least 4 hours.
To dispose of your Libris, please recycle it as you would other electronics containing
rechargeable batteries. Contact your municipality for more information.
Do I need to connect a telephone to Libris?
No, Libris is connected to the TELUS cellular network and does not need a phone line.
No, Libris is connected to the AT&T cellular network and does not need a phone line.
Does Libris have a speaker or a microphone?
Yes, Libris is equipped with both a speaker and a microphone so that you can speak with your
monitoring service through Libris.
Who does Libris call if I need assistance?
Your Libris calls your monitoring service in case of an emergency. They can contact emergency
services to send assistance immediately and also alert your preferred emergency contacts.
When is my monitoring service available?
Your monitoring service is available 24/7 to answer your calls.
Will my Libris call for help if I accidentally
drop it?
In most situations, the smart fall detection can tell the difference between a drop and a fall, and it
will not generate a call. However, if Libris does make a call, simply tell your monitoring service
that Libris was dropped and you do not need assistance.
What if I’ve fallen but do not need help?
If Libris makes an emergency call after a fall and you do not need assistance, simply tell your
monitoring service that you do not need help.
Libris will also announce how to cancel a call as it is making the call.
How do I update my information or my
emergency contact information?
Contact your monitoring service by pressing the center button and request to update your contact
information or that of your emergency contacts.
Can I adjust the volume?
Yes. Contact your monitoring service by pressing the Libris button and request to change the
Where do I get cellular coverage with my

your area, visit
Libris has cellular coverage nationwide on the AT&T 3G network.
To see the coverage in your area, you can:
Check out the coverage viewer:, or
Use a 3rd party coverage checker, such as
Or contact your monitoring service.
Does the Libris need to be turned off during
a flight?
Yes, because Libris uses cellular service, the FAA requires that it be turned off during taxi, takeoff, landing, and during flight.
Is Libris Compatible with my Pacemaker?
We suggest that you contact the manufacturer of your pacemaker and inquire about whether your
pacemaker is susceptible to RF emissions consistent with the frequency of our device. Libris
complies with the rules and regulations required of a transmitting device such as ours. Libris
emits a radio frequency (RF) of 850 and 1900MHz associated with standard 2G and 3G cellular
communication, and it is in compliance with FCC Part 15 restrictions, including those for
radiated emissions.
Will the Libris coverage be improved if there
is a micro cell utilized or a signal booster in
Microcells or signal boosters can be useful for users in poor coverage areas. Libris is a 3G
We have used AT&T's microcells in the past and you can find more information about those
here: However, you will need a separate AT&T account
(phone) to set up the AT&T microcell - your Libris is on an enterprise account and is not enough
in itself to setup the AT&T microcell, although it may be added to the AT&T microcell after
setup. Please use the Contact Support button below if AT&T is not assisting you with setup
Libris with an active microcell.
If you don't have a separate AT&T account, an antennae (non-account) based cell booster may
work best. There are many models out there, including the weBoost Connect 3G Directional
Signal Booster, available from multiple resellers including
Please read the specifications before purchasing any booster to make sure you meet the minimum
requirements, such as space needed for the antennae (can be as long as 100 ft).
What happens to Libris when it is placed in
the Charger?
Libris has a "charger mode" which allows the radio signals to temporarily power down to allow
for faster charging. But if you press the button, the radio signals are immediately turned on.
The following Libris behavior may be turned off for your integration - if you are unsure of the
applicability, please refer to your call center manager before contacting support using the
button at the bottom of the page.
Libris does have a "charger mode" that will allow Libris to enter if placed on the charging
Charger. Charger mode allows the radio signals to temporarily power down to allow for faster
When Libris is in the Charger, both lights will be steady when the radios are on, and only the
battery light will be steady if the radios are off. In other words, anytime the radios are off, the
cellular signal strength indicator (led) is turned off.
Anytime Libris is placed in the Charger, it will initiate a 15 minute interval timer (radios off
delay) at which point, if Libris is still in the Charger, it will turn the radios off.
When the radios are off, while Libris is in the Charger, Libris won't process requests such as
CallNow and LocateNow, until the radios are turned on again (after the 1 hour cycle expires or
when the user pulls Libris from the Charger).
After the radios are off, Libris will initiate a 60 minute interval timer (radios off interval) at
which point Libris will turn the radios back on.
After the radios are on, Libris will connect with the Libris Platform to send any events it has in
its queue and to process any instructions it has in its mailbox. This can take anywhere from 2 to
17 minutes.
Once that work is completed, and Libris is still in the charger, it will turn the radios off and go
through the cycle again.
When Libris is taken out of the Charger, if the radios are off, they are immediately turned on.
The cellular signal strength indicator will be solid for a cycle after which it goes back to the
regular flashing mode (typically every 30 seconds).
When Libris is in the Charger and the Libris button is pressed, if the radios are off, they are
immediately turned on. When the call is over, the radios are turned off and Libris goes through
the cycle again.
What are location services?
Location services may be an option offered by your monitoring service.
Libris is equipped with a GPS (Global Positioning System) antenna and Location Based Services
(LBS) technology that approximate user location, allowing emergency services to find the Libris
user if they are not able to provide their location to the call center.
Verify the location
Location fixes (acquired by either GPS satellite or network) are a tool to help determine physical
user location. Ultimately, it is a human decision to decide how much to trust a particular type of
fix over another. Always attempt to verify the user location verbally before sending emergency
help or ending an emergency call.
When does Libris determine location?
If location services are enabled, thereThere are two instances when Libris approximates its
location, also known as a fix.
Interval Fix is occurs when Libris establishes location at a default interval every ten minutes
(interval period can be customized by the call center). The resulting information is stored on
Libris and is not viewable until Libris is docked in the charger or the monitoring service
remotely pulls location data.
Active Call Fix is occurs when Libris establishes user location during an active call. An active
call can be initiated in three ways: the user presses the call button, the call center initiates a call
from Libris, or a fall automatically triggers a call. Libris attempts to acquire a GPS satellite fix
every five seconds during an active call.
How do the two location technologies work?
Satellite technology is the most accurate means of approximating user location. The GPS
antenna inside Libris scans the sky to receive signals from GPS satellites rotating around the
Earth, which can take up to three minutes.
If the location interval has been set to a frequent period, such as 10 minutes, the GPS module has
the ability to keep track of satellites it has previously located and take less time to obtain a fix. If
Libris is unable to communicate with a satellite beyond an interval time period, the information
becomes stale and Libris scans the entire sky to find satellites.
During an active call, Libris attempts to acquire a GPS satellite fix every five seconds. If it is
unable to find one, a network fix will be returned with the user's approximate location. It is
possible that a structural obstruction will block satellite communication and force the Libris to
report only a network fix. The network fix will not be attempted if the Libris acquired a satellite
fix just before the call.
LBS or Network technology uses a back-end service from the network operator (AT&T in the
US) to help determine a user's location during an active call and when satellite fixes are not
available. LBS (also referred to as network fix, cellular identification (CID), enhanced cellular
identification (eCID), or triangulation) works by using the cell phone number associated with
Libris to approximate location relative to nearby cell towers.
How accurate are the location services?
A satellite fix usually approximates a location to within 50m or less of the Libris actual location.
Accuracy increases with the number of GPS satellite signals the Libris GPS antenna receives.
Libris constantly searches for and prioritizes location fixes determined by satellite. The optimal
conditions in which to establish a satellite fix are outside in an open area with a clear sky.
Conditions that reduce satellite fix accuracy include structural obstruction (being inside a
commercial building or, to a lesser extent, a home), urban density and cloudy weather.
A LBS or network fix usually approximates to within 1000m of the Libris actual location. This
location fix type is estimated due to the inherent difficulties related to cellular strength.

What is fall detection?
Fall detection may be an option offered by your monitoring service.
If fall detection is an option, Libris is designed to sense when you have fallen and automatically
contact your monitoring service. Your monitoring service can talk to you through Libris and
send help if needed.
Does the fall detection need to be calibrated?
Libris offers the most advanced fall detection in the industry. Fall detection is on or off. There
are no sensitivity settings to adjust on it once it is enabled.
How does Libris sense a fall?
The 'sensing' comes from data gathered by an array of sensors located on Libris including
multiple accelerometers, a magnetometer and a gyroscope. These sensors capture data that yield
over 190 different parameters, such as orientation change, impact intensity and impact speed. If
one of Libris' sensors notices an atypical pattern of activity, Libris works to determine if an
actual fall occurred through the following steps:
Immediately after the sensors notice atypical activity, data is recorded for up to 10 seconds as
All of the recorded data is sent over the cellular network to the Libris classifier (located in a
cloud-based server) for analysis.
If the classifier determines that a fall has occurred, a call is automatically triggered to your
monitoring service. This entire process can take 30-45 seconds.
Why does Libris make a call when I have not fallen?
Libris may occasionally place a call to the monitoring service even if you have not fallen (a
False-positives typically occur after activities of daily living that exhibit movement patterns
similar to a fall. For example, quickly lying down onto a bed or getting into a car requires a rapid
change in elevation and orientation. In these instances, Libris sensors categorize these movement
patterns as a fall and trigger the call. It is also common for younger, more active individuals to
experience more false positives than older adults because this feature is calibrated to the motion
activity of an older population. Occasionally, an accidental button press will cause Libris to place
a call.
If a false positive occurs, simply tell your monitoring service that you do not need assistance.
Why doesn't Libris go off when it's dropped or thrown on the floor?
While it seems like dropping it would be a good way to test the fall detection feature, the
parameters captured from a dropped or thrown device do not resemble those of a person who has
fallen, and the classifier can tell the difference. The algorithms are based on data gathered from
actual human falls that yield complicated motion activity not attainable in a drop or throw.
How should I wear Libris for best results?
The Libris can be worn at the waist using the belt clip or around the neck using the lanyard. If
you choose to wear your Libris around your neck, please ensure that Libris remains close to your
chest for best results; many users tuck the lanyard under their clothing.
If a fall occurs, should I press the button or wait for Libris to detect the fall?
You should press the button to place a call if you are able. Otherwise, Libris will automatically
call within 30-45 seconds.
Why will "low battery" alert go off when I
pull device from charger?
Libris is designed to trigger an audio alert if your battery is below 52% charge level.
The next audio prompt will occur when Libris is at 52% battery life. "Charge your personal
mobile responder now. Please place your personal mobile responder in the charger now".
If you charge Libris but it still is below the 52% threshold of battery life, as soon as you pull
Libris from the charger you will be presented with a low battery audio alert.
Does Libris contain latex?
The Libris is not certified latex-free and may be manufactured with equipment that has processed
latex, but Libris does not contain latex.
Materials used in Libris include:
Housing: A non-latex painting over a polycarbonate/ABS mix
Push button: silicon rubber and epoxy
Screws: steel
Clip: polycarbonate, stainless steel and EPDM rubber
Lanyard: polycarbonate, stainless steel, and a nylon strap
Is there any difference between white and
grey devices?
There is no difference between the white and grey devices except the color of paint on the top
cover. They are the same device, except white devices are painted white and grey devices are
painted grey.
Why should we use Libris instead of a cell
Libris has many capabilities that your cell phone does not offer. If Libris detects you have fallen,
its automatic fall detection and GPS location services can help emergency services find you.
And, if you are unable to call for help, Libris can make a hands-free, two-way call to your
monitoring service. Depending on your monitoring service, they may know your emergency
contacts and medical history. Unlike your cell phone, Libris is highly water-resistant and impactresistant.
