defibrillators. Consult your physician and medical device manufacturer for information specific to your medical device and whether you need
to maintain a safe distance of separation between your medical device and Safe Spacer.
If you suspect Safe Spacer is interfering with your medical device, stop using it immediately and consult your physician.
SAFE SPACER IS NOT A MEDICAL DEVICE
Safe Spacer is not a medical device and should not be used as a substitute for professional medical judgement. It is not designed or intended
for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of any condition or disease.
NOT FOR USE IN A POTENTIALLY EXPLOSIVE ENVIRONMENT
Charging or using Safe Spacer in any area with a potentially explosive atmosphere, such as areas where the air contains high levels of
flammable chemicals, vapors, or particles (such as grain, dust, or metal powders), may be hazardous.
Exposing Safe Spacer to environments having high concentrations of industrial chemicals may damage or impair Safe Spacer functionality.

8 CARE INFORMATION
8.1 CLEANING THE WRISTBAND OR BELT LOOP
• Clean the wristband regularly. The wristband is made of
thermoplastic elastomer, and can be cleaned with a mild soap
solution and warm water.
• Do not use abrasive cleaners or silicone-oil based products on
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.
