Intended Use
The EndoLight® is a portable device that is based on the principles of Low-Level Laser Therapy
(LLLT). It is worn around the left wrist for a duration of 30 min/day.
The EndoLight® has 7 laser diodes and one LED diode that are grouped in two light units. They are
positioned so that the light hits the main arteries in the wrist (Arteria Ulnaris and Arteria Radialis) for
an effect on the entire body.
The diodes irradiate the circulating blood with different wavelengths of light and intensities, depending
on the user settings.
The device is powered by a built-in lithium-ion battery.
The EndoLight® is intended for private use only and not for industrial/commercial use. According to
the Product Safety Act, the EndoLight® is not a medical product but a wellness product. Its intended
use is for the improvement of general well-being and was not designed to diagnose, cure, alleviate, or
treat any disease, symptoms, or other medical problems.
Please note that in the event of improper use, liability is void.
Contraindications
Use in infants and children under 16 years of age, pregnant women and in case of pre-existing
conditions only after consultation with a doctor.

General
Some basic safety precautions must be taken into consideration when using electrical equipment.
Failure to take precautions outlined in this section could result in fire, electric shock, other injuries,
damage to the EndoLight® or other property. Please read the following safety instructions carefully
before use.
This information relates to the EndoLight®, the charging and data cable, the power adapter, and all
accessories.
Always keep these operating instructions on hand and store them in a safe place so that you can pass
them on to the new owner in the event of a sale.
Safe use of the EndoLight® is the primary responsibility of the user. If the EndoLight® appears to be
operating incorrectly, please refer to the troubleshooting guide. Contact us if the problem persists.
Safety instructions
This hazard warning indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury.
Skin reactions
Wearing the EndoLight® can cause skin irritation or allergic reactions. To avoid this, you should
always keep the device clean and dry. Please do not wear it too tight around your wrist.
If the irritation persists, take the EndoLight® off your wrist, and contact your doctor if the symptoms
persist for more than 3 days.
If you experience pain, numbness, or a burning or tingling sensation while or after wearing the device,
remove it immediately.
Due to the high-power output, it is normal that the EndoLight® generates heat (approx. 40 degrees
Celsius or 104 degrees Fahrenheit). Skin with a higher proportion of melanin absorbs a higher amount
of laser light and can therefore heat up more likely. Observe your skin reaction particularly carefully if
you have dark skin (skin type V or VI).
If the EndoLight® becomes uncomfortably hot while it is being used or charged, or if it produces
unusual noises or smoke, immediately remove it from your wrist or unplug it from the socket.
Physical discomfort
Consult your doctor and temporarily stop using the device if you experience physical symptoms such
as seizures, fainting, eye aches or headaches that you suspect may be caused using the EndoLight®.
Product damage
If your EndoLight® has been damaged, do not use it anymore.
To avoid injury, do not try to open or disassemble the EndoLight® yourself.

6

3. Your EndoLight®
Material
The structure of the EndoLight® is made from aluminum.
The wristbands are made of a hard-wearing silicone rubber that is particularly comfortable to wear
thanks to its high-quality material properties.
Other materials used are quartz glass and medical grade polycarbonate plastic.
All materials are BPA-free.
If the original wristband is too large for you, you can replace it with the smaller one, which is included
with the EndoLight®. Please refer to chapter 4 on further information on how to change the wristband.
The buckle that fastens the wristband is made of stainless steel.
Diodes
The device is a Class 1C laser device. Special proximity sensors ensure that the diodes are only
activated when they are in contact with skin. This reduces the risk of eye damage to the user or a by-
stander through direct exposure to LED or laser light.
Graphic 2: Safety label on proximity sensor
The core feature of the EndoLight® are the two uniquely designed diode units that deliver their power
in an optimally dosed manner. Special lenses collimate and guide the light directly through the skin,
into the arteries. This lens is made of PMMA and has features that, in addition to the contact sensor,
ensure user safety.

5. Recommendations for use
Wear your EndoLight® whenever you want it to support you in everyday life. We recommend one daily
session of 30 minutes. Maximum sessions per day: 2.
At the beginning, start with low intensity (25 % - 50 %) and observe your reaction. You can then
gradually increase the power from session to session depending on how you feel.
6. Storage and cleaning
Store your EndoLight® in the provided storage case when not in use to prevent dust and debris getting
inside the device.
Perspiration can develop during the session. We recommend wiping the surfaces after use with the
provided cleaning cloth. Alternatively, you can use an abrasion-resistant, lint-free cloth for cleaning.
You can use water or cleaning alcohol (such as isopropanol 70 %) to moisten the cloth. First spray this
onto the cloth and not directly onto the device. Make sure that the cloth is only damp and not wet.
Never spray cleaner directly on the device. Damage due to the ingress of liquids or solvents will void
the manufacturer’s guarantee. Use of other cleaning products may damage your EndoLight®.
The EndoLight® should only be cleaned when it is turned off and not while it is charging.
CAUTION: Do not use cleaning products that contain ammonium chloride. These chemicals
may cause cracking of the material.
7. Product durability
The EndoLight® is designed to be durable under typical use.
The device is equipped with parts that are subject to natural wear and tear (e.g., the rechargeable
battery). The service life of these parts depends either on their frequency of use or is limited in time.
These parts can possibly be replaced by our service team.
