14.0 Flex Timer Instructions
14.1 Determining a Treatment Time
When using time as a dose, there are two treatment methods that can be used. The simplest is to start
at a prescribed time and then increase treatment times by a specific time increment or by a percentage.
Another method is to use the factory power output levels (shown on the Power Output Certificate) to
determine estimated “time equivalents” needed to deliver doses in Joules (UVA-1).

MNL-00024 [1] Proprietary and Confidential Page 13 of 21
To determine a “time equivalent”, consult the laminated Time Chart that is provided and find the power
output on the top row (horizontal axis). The numbers in the left most column (vertical axis) represent a
range of potential treatment doses. Find the dose then trace that row to the right until it intersects with
the column corresponding to the factory power output of the device. The time equivalent is shown where
the two lines intersect. For example, if the factory power output is 8.0 mW/cm2and the dose to be
delivered is 2 Joules, then the appropriate treatment time will be 04:10. A partial time chart illustrating
this is shown on the following page.
Note: For your convenience, and as an alternative to the UV time chart, the latest version of our free
iPhone and Android application “Phototherapy Math” is available for download at the iTunes app store
and Android market. It quickly calculates treatment times, backup safety times, and makes the
calculation of dose and time increases simple. If using a PC, visit www.phototherapymath.com for a web
based calculator and additional information.

15.0 Treatment Protocols
15.1 MED Testing
The more accurate but more complicated method of determining a patient's initial dose is through MED
testing. Because this is a cumbersome process, many doctors do not wish to determine a patient's initial
dose in this manner. However, before we discuss the procedure in greater detail, let us first define the
terms.
MED stands for Minimum Erythemal Dose and is defined as the minimal dose of UVB that will cause
marked erythema on a patient's skin. As an example, a skin type IV will have an MED somewhere within
the range of 200-600 milliJoules of narrow band UVB. See Protocols for all skin types and ranges.
MED testing results in a more accurate starting point. Because of the subjective nature of a patient's
response to the skin-typing quiz, the empirical method is more subject to error. In many cases, testing will
show that a patient may be more tolerant to ultraviolet than would have been suggested by simple skin
typing.
It is important to start phototherapy patients at as high a dose as possible. Underdosing a patient causes
excessive tanning that means that the patient must undergo more and more aggressive treatment just to
overcome the natural UV screening effect of tanned skin. This results in an excessively high cumulative
dose to clear the patient's disease.
When setting up a UVA-1 patient, the key element in determining exactly how much UVA-1 radiation the
patient will receive is the MED. The first UVA-1 treatment is always a percentage of the MED that has
been entered. Thereafter, each succeeding treatment is some percentage of the preceding dose. Each and
every dose is mathematically related to the MED value,whether this value was determinedby MED testing
or by skin typing.
The following section provides instructions on exactly how MED testing is carried out in the doctor's office.
15.2 MED Testing Procedure
The first stage in performing MED testing is to determine the patient’s skin type. The patient’s skin type
is then used to determine the dosages that will be used to perform MED testing. Many physicians use a
simple table of questions to determine a patient's tolerance to light. The table is reproduced below:
Skin Type
History
Skin Type I
Always burns, never tans
Skin Type II
Always burns, sometimes tans
Skin Type III
Sometimes burns, always tans
Skin Type IV
Always tans, never burns
Skin Type V
Brown skinned (Chinese, Mexican American)
Skin Type VI
Black
Once you have determined the patient’s skin type you can proceed to the testing stage.

MNL-00024 [1] Proprietary and Confidential Page 16 of 21
15.3 Daavlin Dose Patch (sold separately)
The Daavlin Dose Patch is a disposable adhesive MED/MPD test panel. There are six exposure windows
measuring 2cm x 2cm. The panel is applied directly to the patient’s skin like a bandage. The Dose Patch
is hypoallergenic and can be used for all skin types.
15.4 General Instructions for MED Testing
Dose Patch can be used on any part of body. Non-exposed areas of
arms, buttocks and back are common test sites. Protect the patient’s
eyes and cover areas not being tested with UV blocking clothing or
sunscreen. The person doing the testing should also take protective
measures against incidental exposure.
Remove the two adhesive end pieces on the back of the patch. Apply
the patch in the desired location. Make sure it is stretched tightly across
the skin. Use two or more patches if more than six exposure levels are
required.
Determine the doses you will test for (recommended doses below).
Open exposure window #1. Begin the test by exposing entire patch
area to ultraviolet light source. As each dose level is reached, open
exposure windows in consecutive order. The last window opened equals the lowest dose; the first window
opened equals the highest dose.
The patient will need to return in 48 hours to have the test results read for UVA-1. The resulting MED will
now be the initial MED for setting up the patient for the first treatment.
15.5 RECOMMENDED PROTOCOL FOR UVA-1
Irradiation 5 x week for 3 weeks (altogether 15 exposures) Determination of the UVA 1 MED prior to
treatment Start with 1 MED if MED < 70 J/cm2. Increase of the dose by 20 % every time if there is not an
erythematous reaction and by good tolerability until a maximal dose of 70 J/cm2.

16.2 Cleaning
We suggest using “Monk” Brand Wipes for exterior cleaning as they disinfect and will not harm any
ultraviolet or light transmitting surfaces. These wipes are available for purchase through Daavlin. When
dusting the unit we recommend using a feather duster or a similar non-abrasive cleaning device.
16.3 Cleaning of the Filter
A trained technician should clean the internal filters and cavities of the machine annually. Do not
attempt to clean these filters without proper training, as certain solutions may damage the filters. Only
Daavlin authorized personnel should perform this function.
Allow the filters to cool down.
Use a vacuum to remove dust from black filters on both sides of each lamp column.
Depending on the frequency of use and the location of the unit, the filters may collect dirt. This will impair
UV intensity.
16.4 Relamping
Only Daavlin authorized personnel may carry out lamp replacement
The UV output of the lamps typically degrades to unacceptable levels after 500-800 hours of use. Only
use the replacement lamps specified in this manual when relamping. Although other lamps may fit and
light, they may also produce excess amounts of UVB which could be harmful to the patient. Always return
lamp filters to their original position after relamping. Follow all federal and local regulations when
relamping and disposing of discarded lamps.
Note: Always measure lamp intensity before and after lamp replacement. It is important to notify
everyone concerned that the lamps have been replaced as patient exposure times may need adjusting.

16.7 Troubleshooting
Problem
What To Do
Deposits in the glass cylinder
of the lamp
It is quite normal for deposits to collect in the glass
cylinder of the lamp after the lamps have been
switched off. These deposits are the result of the
metal halide precipitating inside the lamp when it
cools down. They will disappear completely once
the lamp is switched on and warms up again.
The lamp does not ignite.
When troubleshooting the problem, please note in
certain, rare cases, it may take up to 2 minutes for a
lamp to ignite (such a lamp will ignite normally once
it has been ignited several times).
*Make sure that the main switch is on.
*Make sure the unit is properly plugged in. (Check
all plug connections.)
*Check all fuses in the unit and the building.
*If the lamp is defective, change the lamp.
*If the ignition unit is defective, contact the Daavlin
Service Department.
*If it is impossible to ignite the lamp or if the lamp
produces only a weak, bluish light, switch the device
off immediately to prevent damage to the ignition
units. Contact Daavlin Service Department.
Filters have slipped or are
defective
Never operate the unit if the filters have slipped or
are defective. Switch the device off. Contact
Daavlin Service Department.
