6 SOCIAL DISTANCE WARNING
Social distancing between workers is ensured by alerting them if
they come too close to each other.
The social distancing warning thresholds can be configurated with
dedicated software or the command line interface (CLI).
Default threshold values:
2m / 6.56ft
1.2m / 3.94ft
RED
• ALERT 1: When the distance between two or more units is
between 1.2m / 3.94ft and 2m / 6.56ft, the lights on the unit will
flash red and the unit will vibrate every 2 seconds.
1.2m / 3.94ft
RED
• ALERT 2: When the distance between two or more units falls
below 1.2m / 3.94ft, the lights will flash red and the unit will
vibrate every second, accompanied by an intermittent sound alert
(IK141-108 version only).

7 CONTACT DATA LOG
The Safe Spacer can work as a proximity alarm and/or a contact
tracing device.
The two features can be anabled or disabled independently.
When contact tracing is active, each device that comes within 2
meters is logged, regardless of the alarm status and the alarm
threshold settings.
The idea is to log the most reliable contact tracing data possible,
independent of distance and/or time thresholds that may change.
It is possible to enable/disable the contact data log via the dedicated
software or command line interface.
• By default, the contact data log is disabled: to turn it ON,
connect the unit to a computer: the Safe Spacer software
can automatically set date and time and turn on contact data
logging. Alternatively, you can use the command line interface
(CLI) to set date and time and then turn contact data logging on
manually.
7.1 ERROR MESSAGES
Once data logging is enabled, it is advisable to download the data
regularly to prevent the internal memory from filling up.
If the internal memory
becomes full, or date and
time are not valid, the Safe
Spacer will blink purple
rapidly every 2 seconds until
the data log is downloaded
or date and time is properly
set.

the wristband, as it can deteriorate the material.
• The strap can be sanitized by wiping it with isopropyl alcohol.
Remove the Safe Spacer casing from the wristband before doing
so.
• After cleaning, dry the wristband with a clean, lint-free cloth and
let it air dry before using it again.
8.2 CLEANING THE DEVICE CASING
• Clean the casing of Safe Spacer with a damp cloth or a mild
soap solution. Don’t use abrasive cleaners.
• The casing of Safe Spacer can be sanitized by wiping it with
isopropyl alcohol. Do not boil or autoclave the casing of Safe
Spacer, as this may cause permanent damage to the device.
• After cleaning, dry the casing of Safe Spacer with a clean, lint-
free cloth and let it air dry before using it again.
NOTICE: As the effectiveness of certain cleaning products and disinfectants against COVID-19 are not
yet fully known by health authorities, IK Multimedia recommends checking the latest guidelines, which
can be found on www.ecdc.europa.eu.
8.3 ALLERGY INFORMATION
• Safe Spacer is designed to the highest safety standards and
manufactured from high-purity materials.
• As with all things worn close to the body, moisture and bacteria
can cause irritation when wearing a wet or dirty wristband for
extended periods of time. If you have known skin sensitivities,
please take special care when wearing Safe Spacer. Clean the
band and wrist regularly, especially after intense sweating or
working in very dirty environments. Be aware that products
such as lotions, perfume, soap or insect repellants are known to
get trapped under items as jewelry and wristbands and cause
irritation.
• Do not use aggressive products to clean the wristband.
Keeping Safe Spacer and the band clean and dry will reduce the
possibility of skin irritation.
• Take off the safety wearable when not using it, to allow your skin
to breathe. If you experience redness, swelling, itchiness, or other
irritation on your skin around Safe Spacer, remove the device and
consult your physician.

10 SAFE SPACER SOFTWARE – QUICK START GUIDE
TheSafe Spacer softwarefor Mac/PC allows you to control Safe Spacer settings and access contact
tracing information. The convenient interface gives you essential data at a glance, so you can ensure
employees are respecting social distancing and easily adjust the device settings.
When opening the app for the first time, you will be asked to fill out a simple form with your personal
information and set a password to protect contact tracing data.
PLEASE NOTE: remember to store your password safely, if you lose it you will no longer be able to
access the contact tracing data.

last sync date and status icons. The status icons tell if a device is
compliant (green icon), non-compliant (yellow icon) or at risk (red
icon) in a period of time of your choice that you can select from
the dropdown menu above the graphics. “Compliant” means the
device is respecting the default security distance of 2 meters (6.6
feet), “non-compliant” means the device crossed the threshold of
2 meters and it is not in a safe area anymore, while “at risk” means
the device is in a risk position, closer than 1.2 meters (3.9 feet). It
is also possible to filter the device list “by status” or simply use the
sorting options to re-arrange the list. In addition, if you want to flash
the synced devices to make them recognizable, just click on the
blinking icon positioned on top of the device list.
Charts: On top of the Safe Spacer pane, 3 charts display the Compliant, Non-Compliant and At-Risk
devices on a graphic timeline. You can set a time scale and choose from: last 24 hours, last 7 days and
last 14 days. The selected time scale will affect the charts and the device list on the left of the interface.
On top of each chart, the number of compliant, non-compliant and at-risk devices based on the selected
time scale is shown.
Interaction Pane: On the device list, click on a device and the Interaction Pane will appear at the center
of the interface. From here you can see the list of interactions between the selected device and all the
other registered devices. You can set the arrangement of the list by:
“Interactions with”, “Last interaction”, “Number of interactions”, “Minimum Distance” and “Interaction
Time”.
