Medical explanation of the effect of light therapy
Today we know that sun light acts like a natural clock for many of our physiological processes. Bright light travels in the
form of electric impulses via the eyes and the optical nerves to the nervous system's inner timer in our brain. This "time
giver" processes the information about light and darkness and instructs other parts of the brain to rhythmically distribute
chemical messengers. Bright light thus stimulates the production of chemical messengers which influences the mood and
suppresses the production of the body's sleep inducing hormone.

Some basic information before using the light therapy units
Before use, kindly check that the instrument is in functional order and that there is no sign of damage. The user must check
that the equipment functions safely and see that it is in proper working condition before being used. Do not position the
equipment so that it is difficult to operate the disconnection device. Phototherapy instruments must only be operated
in dry and closed rooms that are free of any explosion risks. The device is not suitable for use in the presence of flammable
anesthetic mixtures with air or with oxygen or nitrous oxide. The instruments must be standing free and should not be
exposed to sun.
How to carry out light therapy
Place the instrument on an even surface and connect the plug with a wall socket. Sit down in front of the instrument and
keep a distance of approx. 55 cm in case of the LD 72 and a distance of approx. 45 cm in case of the LD 110. The treatment
time with the LD 72 is at the above mentioned distance approx. 2 hours and approx. 1 hour in case of the LD 110.
If you use the LD 72 or LD 110 move the tilting switch to „On" and the device begins to glow. The LD 72 and LD 110 must
be switched off manually.
Keep your eyes open during the treatment. You are in the position to read, watch TV or carry out any other activities. After
every 1 – 2 minutes you should look for a few seconds into the light source. A constant staring into the light source must
be avoided. If you want to cover the phototherapy instrument after use allow the instrument to cool down at least 15 minutes.
Important: In order to be protected against UV-rays, the light box must only be operated with its original
protective filter in place.
