2.2 Electrical Shock Hazards
Warning: To avoid the risk of an electric shock, the device must only be connected to a
power supply with a protective earth. The power supply must be in accordance with all
national and local installation regulations. The device may only be operated with the power
supply voltage specified on the nameplate.
Warning: Prior to each use, always verify that the device is in correct working order and
operating condition. Therefore check also plugs, wires, switches and other control devices, as
well as the irradiation unit and all mechanical components. Upon discovery of faulty, worn,
or damaged component(s), MEDlight authorised service personnel must replace the
component(s) and test the device prior to placing the device in use again.
Warning: If you notice unusual noises, smoke, sparks or burning smell from the device,
immediately switch it off and do not put it back in operation. Contact MEDlight for a repair,
and do not use the device again until it is repaired, tested and released by MEDlight
authorised service personnel.
Warning: Open under no circumstances the device housing. Turn off the device when it is not
used.
Warning: Place the device in such a way that the mains plug or the mains connection remains
easily accessible at all times in order to enable a disconnection from the mains.
Warning: Ensure that the device is serviced at least annually, by MEDlight authorised service
personnel.
2.3 Light Exposure Hazards
Warning: The UV light of the device can lead to serious eye injury. To protect the eyes during
operation, patients must wear tightly fitting UV blocking goggles, and the operator and
anyone in view of the device must wear protective UV blocking glasses or goggles. Suitable
UV blocking glasses and goggles are included in the delivery contents. It is recommended to
provide an individual pair of glasses for ever user, and an individual pair of goggles for every
patient. If required, further goggles can be obtained from MEDlight. Furthermore it should be
avoided to look directly into the light, during operation. In order to protect personnel from
stray UV in the vicinity of the device, it is recommended to operate the device only in a
designated treatment room. Operating personnel exposed to UV radiation for any prolonged
periods of time should wear long-sleeved clothing and gloves and use barrier creams with a
high light protection factor on exposed skin areas.
Caution: To ensure an all-around homogenous light exposure, the patient must stand in the
middle of the cabin. Instruct your patients to remain in this position throughout the entire
treatment to avoid partial overdosing.
Caution: Use of controls or adjustment or performance of procedures other than those
specified in this user manual may result in hazardous radiation exposure.

2.4 Other Hazards
Warning: Modifications of the device are not allowed. Operate the unit therefore only with
original equipment, supplied by MEDlight.
Warning: Do not store or operate the device in humid areas. The device must never be
directly exposed to flowing or splashing liquid or water. Also, be careful when cleaning with a
damp cloth to ensure that no liquid enters the device.
Warning: The device must not be operated in the presence of a flammable anesthetic
mixture with air, oxygen or nitrous oxide or where flammable substances such as alcohol,
fuel or similar substances are used.
Caution: Make sure that the UV sensors of the cabin are not covered during the treatment.
Especially with very large patients, make sure that there is always a minimum clearance of 5
cm (2") between the patient and the cabin roof. Otherwise, the patient's head could interfere
with the measurements of the UV sensors.
Caution: Patients with a body weight of more than 180 kg (395 lb) must not be treated in this
cabin.
Caution: Lay the power cord so that there is no danger of tripping up a person.
Caution: Ensure that the ventilation slots of the device are not covered, so that sufficient air
circulation is ensured.
Caution: For reasons of hygiene, we recommend to lay a new disposable paper towel on the
floor plate of the cabin before each treatment.
3OPERATION & HANDLING
3.1 Handling
The device shall only be installed by authorised MEDlight technicians. A detailed device training usually
takes place immediately after installation. Additional trainings can be arranged upon request.
Plug the mains plug of the cabin in a protectively earthed CEE outlet which is fused with 16 amps fuses.
As soon as the cabin is switched on via the green mains switch on the left side of the touch screen
console and the touch screen booted up, the cabin is ready for use. Please, switch the device always off
via the green mains switch, if the cabin is not in use for a longer time and at the end of each working
day.
To protect the cabin against unauthorised use is also recommended to set up a PIN code (see section
3.3.7).
The well-structured menus of the touch screen allow an easy intuitive operation of the device. To
navigate through the menus just tap the desired button or a menu or use swipe gestures to go back and
forth between different menus.

For enhanced safety and comfort during operation the onscreen navigation is accompanied by voice
messages of the system. These voice messages warn you e.g. if certain dose levels are exceeded, and
inform the patient about the remaining treatment time.
When you open the cabin door and look up, you will see an oval casing mounted on top of the cabin
roof. This casing holds the UV measuring unit of the cabin's dosimetry with a total of four sensors, which
continuously monitor the irradiance of the UV tubes during treatments. This ensures a precise
application of doses, even if the irradiance of the UV tubes changes, because the exposure times will be
accordingly adjusted in real time by the dosimetry.
The cabin door is equipped with a door contact which shuts off the UV tubes and pauses the treatment
whenever the cabin door is opened. This protects the operator from UV exposure and allows the patient
to interrupt the treatment if necessary.
Inside the cabin are two long handrails to which the patient can hold on to during treatment. On the
right handrail is a patient panel mounted, which is equipped with an emergency off ripcord switch. The
end of the ripcord can be affixed to the patient's upper arm with the aid of a Velcro noose to
automatically actuate the emergency off switch in case the patient collapses during treatment. In this
event the UV tubes shut off and an audible alarm is activated.
On top of the cabin is a patient fan mounted, that comes on automatically with the other fans of the
cabin during treatment. This fan delivers an airstream which makes in particular longer treatments more
comfortable for patients. In case a patient doesn't want this airstream, the patient fan can be switched
off with the switch in the patient panel.
3.1.1 Optional Features
The N-LINEpro cabin is network capable and therefore equipped with an according network connector
on the rear side of the left cabin module. This allows to connect the cabin via a network cable (at least
Cat6) to a Windows® PC from which it can be remotely operated in conjunction with the MEDlight
SKINdex software. To prevent an unauthorised use of the cabin’s touch screen it is automatically locked
during remote operation.
Besides the remote operation of the cabin, the SKINdex software offers an extensive set of practice
approved features for patient management and treatment planning.
To keep in touch with patients also during remote operation, MEDlight offers an optional intercom
system that enables a bidirectional communication via network. For this purpose the patient panel
inside the cabin is already equipped with a microphone and a speaker. The microphone in the cabin
becomes active at a certain sound threshold, and therefore works automatically as soon as the patient
says something.
Some patients might need special attention and therefore require to be checked from time to time
during treatment. For this reason the cabin is equipped with a viewing window. To provide the same
level of attention also during remote operation, MEDlight offers an optional surveillance camera for the
N-LINEpro. The video signal is broadcasted via network, and can be viewed right in the SKINdex
software.

3.2 Operation
3.2.1 Stand-By Mode
After switching on the device, the
touch screen shows the display shown
on the right. If your cabin is equipped
with only one lamp type, only the
output of the corresponding spectrum
will be displayed. The green bar to the
right of the mW/cm² value is for
orientation with respect to the
condition of the UV tubes. The more
the UV tubes lose power over time
due to wear, the more the green bar
decreases. At very low output of the
UV tubes, the colour of the bar then
changes to red. In order to ensure an uninterrupted use of the cabin, it is advisable to replace the UV
tubes when the green bar is only half the original length. To proceed with the selection of the desired
therapy parameters, please press the CONTINUE button.

3.2.5 Therapy
During therapy, all relevant treatment
parameters such as dose, treatment
time and light output of the currently
active UV tubes are displayed on the
screen. The exposure time is
calculated in real time according the
actual UV output, which is
continuously measured by four
sensors. It is therefore normal that the
displayed time is slightly bouncing
instead of elapsing continuously in
one-second increments.
The end of the therapy is indicated by
an acoustic signal, the UV tubes switch off automatically and the program returns to the menu
described in section 3.2.1. Should it be necessary to cancel an ongoing therapy, you can do this by
pressing the CANCEL TREATMENT button. In this case the lamps switch off immediately, and the program
also returns to the menu described in section 3.2.1. However, if you only want to interrupt the
treatment for a short while rather than to cancel it completely, press the SUSPEND THERAPY button or
simply open the cabin door. In this case, the UV tubes switch off and the exposure time is paused. As
soon as the SUSPEND THERAPY button is pressed again, respectively the door is closed, the UV tubes switch
on again and the therapy continues.
3.3 Menus & Settings
3.3.1 Settings
In this menu you can set the date and
time and select the desired system
language. The cabin has a notification
system with spoken announcements.
The user and the patient are thus
provided with warning and safety
instructions in a comfortable manner
as well as useful information on the
treatment (e.g. announcement of the
remaining treatment time). This
announcement system considerably
increases the operational safety of the
device and is therefore activated by
default. If these announcements are not desired, they can also be deactivated by pressing the AUDIO
NOTIFICATIONS button.

overview of the last 100 treatments
that were carried out with the cabin.
The entries are sorted by date and
each line contains all treatment-
relevant information such as the
spectrum of UV tubes used, dose and
treatment time. For treatments that
have not been completed, the
corresponding entry is shown in red.
To view older entries simply swipe
your finger from the bottom to the top
of the list area.
3.3.3 Info
In the INFO menu you can see the
operating hours of the UV tube types
used. You will also find information

the respectively defined menu items.
Enter the assigned PIN and press the
enter key (). The window with the
PIN prompt closes and you can now
continue with the operation as usual.
3.4.3 Maintenance Required
To ensure the safe operation of the
device, annual maintenance is
recommended. To ensure that
maintenance is not forgotten, an
authorized technician can set a service
interval in the service menu as
needed. In this case a corresponding
reminder appears on the screen each
time the cabin is switched on. You can
close this reminder by tapping the 
in the upper right corner of the
message window. Afterwards the
cabin can be operated as usual.

3.4.4 UV Output Low
The device is equipped with a so called
dosimetry which continuously
measures the irradiance during
therapy, and adjusts the exposure
time accordingly in real time. If this
measuring system detects a fault
during treatment, e.g. if some UV
tubes or a sensor have failed or a
sensor has been covered, the device
aborts the treatment and a
corresponding message appears on
the display. In this case check if all UV
tubes are actually working (see section
3.3.3). Afterwards carry out a test treatment without patient, which takes more than two minutes.
Should the fault still persist after the test treatment, please contact the MEDlight service!
3.4.5 No Connection
The touchscreen is connected to the
controller of the cabin via an internal
network connection. If communication
over this network connection is
interrupted, e.g. because a network
cable or the internal network switch is
defective, the message NO CONNECTION
is displayed. In this case, contact an
authorised MEDlight service technician
immediately to resolve the issue.

6SIDE EFFECTS
6.1 UVB –Side Effects
The most common acute side effects include sunburn-like erythema after UVB irradiation.
Without eye protection acute conjunctivitis and keratitis may occur.
After UVB phototherapy, however, no reliable increase in the risk for basal cell carcinoma
was so far observed. Recent works confirm this also for the narrowband-spectrum
application in contrast to theoretical considerations that want to ascribe a 50% risk increase for
carcinoma to the narrowband spectrum UVB therapy.

6.2 UVA –Side Effects
The most common acute side effects are phototoxic reactions due to an overdose
irradiation in the context of photochemotherapy. Without eye protection acute
conjunctivitis, keratitis and for UVA or PUVA treatment a chronic cataract may occur. The
provocation of photodermatoses, mainly polymorphic light eruption, is possible, particularly
in the higher dosed UVA therapy. If inadvertently phototoxic substances or drugs are supplied externally
or systemically, excessive phototoxic skin reactions may occur, especially in UVA treatments or
photochemotherapy.
Occasionally, a PUVA-itching may occur, which can therapeutically hardly be influenced, and sometimes
leads to the discontinuation of the therapy. Rarely, acral blisters appear during PUVA treatment due to a
loosening of the dermo-epidermal border zone with strong mechanical stress. The potential systemic
toxicity of the photochemotherapy encompasses nausea after the tablet intake and occasional
