16.0 Operating the Control Systems
Daavlin Flex controlled phototherapy equipment is available with two distinct control systems, a
Flex Timer and a Flex Dosimeter. Please verify the type of control system incorporated in your
unit and proceed to the applicable operating instructions.
17.0 Flex Dosimeter Instructions: UV Series, 7 Series, M Series, and
4 Series
Your Daavlin phototherapy unit features a built-in power meter that measures energy output.
Once a dose and backup time have been selected the unit will use the information gathered by
the sensor to determine the exact amount of time that each treatment will last. The dose is
entered in milliJoules for UVB and Joules for UVA.

MNL-00007 [3] Proprietary and Confidential Page 17 of 63
The output of fluorescent lamps varies with age, use and other factors such as room temperature.
Integrated Dosimetry measures for such variations and then integrates them into the dose
treatment time resulting in a very effective way to ensure the precision and consistency of each
treatment.
Figure 8 UVA J and UVB mJ
17.1 The Backup Time
An important safety feature of Daavlin’s Integrated Dosimetry System is the use of a safety
backup time. While the dose is entered in Joules or milliJoules, a backup time must also be
entered as a safety check. The treatment will stop when the dose has been delivered, OR, when
the backup time has elapsed, whichever comes first. At the end of the treatment, the dose
delivered and the time elapsed are alternately displayed so that you will know which limit ended
the treatment.
When preparing for a treatment, the back-up time is entered first. To determine an appropriate
back-up time, it is necessary to know the power output of your device.
17.2 Measuring the Power Output of Your Device
The power output value of your device, as measured at the factory, is shown on the Power
Output Certificate included with your device literature.
Note: It is not necessary to take a power output reading before each treatment. We suggest once
every couple of weeks or earlier if the backup time ends your treatment before the full dose has
been delivered.
1. When just a decimal point is displayed, the device is “asleep“(energy saving feature).
Press MODE or any key to “wake up” the device.
2. The word “CODE” will appear. Enter in your key code. Unless you have changed it, the
factory preset key code will be 0007.
3. Once the safety key code, if activated, has been entered, press the ▲ key five times. The
screen will read “00:05”.

MNL-00007 [3] Proprietary and Confidential Page 18 of 63
4. Press the ◄ key two times. The screen will now read “05:00”.
5. Press the ENTER key one time to lock in the backup time.
6. Press the MODE key one time to switch to dose entry mode.
7. Press the ▲ key five times. The screen will now read “0005”.
8. Press the ◄ key until 5000 is displayed if checking a UVB device or 50.0 is displayed if
checking a UVA device.
9. Press the ENTER key one time to lock in the dose.
10. Press the ENTER key a second time to begin the treatment. The lamps will now come
on. When measuring ultraviolet be sure to apply SPF 30 sunscreen to exposed areas of
the skin and wear goggles while monitoring the device.
11. Once the treatment begins press the MODE key one time to view the time counting
down. Allow the device to run until 30 seconds remains. While waiting step away from
the unit to limit unnecessary exposure to UV light.
12. With 30 seconds remaining press the POWER key one time. The system will display the
power output of the lamps. A value such as P9.0 (example) will display. Write down the
value.
13. When the machine shuts off, press the END key to clear the treatment and return the unit
to its energy saving mode.
Once you know your power output (9.0 mW/cm2 in the example above) consult the
laminated Backup Time Chart, a partial example of which is included Table 2 Partial
UVB Backup Time Chart below. The numbers in the top row of the chart (horizontal
axis) represent a range of power output values. Find the value that is closest to the power
output of your device.
The numbers in the left most column (vertical axis) represent a range of treatment doses.
Find your desired dose and trace that row to the right until it intersects with the column
corresponding to the current power output of your device. The backup time is shown
where the two lines intersect. The times are rounded up to the nearest 10-second
increment. On the partial time chart thirty (30) seconds is the backup time for a power
output of 9.0 mW/cm2 and a dose of 280 mJ.
Table 2 Partial UVB Backup Time Chart
The UVA Backup Time Chart (not shown here) is configured the same as the UVB Backup Time
Chart however the doses are listed in Joules and the energy output levels and backup times are
different than the UVB output levels. Each chart is clearly marked.

Note: For your convenience, and as an alternative to the UVB backup 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.
17.3 Setting up a Treatment
You will first enter a backup time (steps 1 –6). Based on the example above the back-up time
will be 00:30.
1. Press any key to awaken the unit. The word “CODE” will appear.
2. Enter in your key code. Unless you have changed it, the factory preset key code will be
0007.
3. Once the key code is entered, the display should read 00:00.
4. Press the ▲key until the first digit of the backup time is displayed (“3” in this case).
5. Press the ◄ key to move the “3” one space to the left, display should now read 00:30.
6. Press ENTER to lock in your back up time.
Now you will enter the actual dose. Continuing our example from above the dose will be 280
milliJoules. Therefore, the first digit will be the number 2.
1. Press the MODE key to switch to dose mode. The display should now read 0000.
2. Press the ▲key until the number “2” is displayed.
3. Press the ◄key to move the “2” one space to the left.
4. Press the ▲key until the number “8” is displayed.
5. Press the ◄ key to move the “8” one space to the left and repeat until all desired digits
are shown on the display. In this example the last digit is a zero, so once you have moved
the “8” into position, the “0” already shows and you can move on to step 6.
6. When the desired dose is displayed, press ENTER to lock in your dose.
7. Put on your goggles and position yourself per the instructions.
8. Begin the treatment by again pressing ENTER
To repeat the same dose for another exposure, press the END key to clear the display. Then press
the MODE and POWER keys at the same time and release. This will automatically bring up the
last treatment administered. Press ENTER to start the treatment.
Note: The system beeps three times to signal the end of the treatment and then flashes the
delivered dose on the display alternating with the elapsed time. If the complete dose is not
delivered, meaning that the backup time was reached before the dose was fully delivered, this is
an indication that the backup times being entered are not long enough. Verify that the sensor is
clean, unobstructed and centered in the hole of the reflector. Then, re-take your power output
reading and adjust the back-up time. It is normal to have to increase back-up times due to aging
lamps and/or because of slow starting lamps, low room temperatures or low line voltage.

17.4 Special Functions of the Integrated Dosimeter
To pause an active treatment press either the END or ENTER key.
•When a treatment is paused the screen will read “HOLD”. To resume a paused treatment,
press the ENTER key.
•When a treatment is in progress press the MODE key to toggle between watching the
dose administered count up or the treatment time count down.
•To check the power output while a treatment is in progress press the POWER key.
•To end or cancel an active treatment press the END key two times.
•If you make a mistake while entering a dose or backup time, repeatedly press the ◄ key
until all zeros are displayed.
•To check the age (in hours) of your lamps press and release the MODE and ◄ keys
together at the same time. The lamps must be off to do this.
17.5 Special Notes
It is not possible to enter a backup time of 60 seconds. You must enter 1 minute instead.
•A short beep is sounded for every valid key entered. A long beep is sounded when an
invalid key is entered.
•If power goes off during a treatment, the system will remember how much of the
treatment has elapsed. When power is restored, your device will be on “HOLD”. To
continue the treatment, press START. To cancel the treatment press END.
•The small orange light above the display will be lit when a treatment is in process. It will
blink when the treatment is paused.

18.0 Flex Dosimeter Instructions: 1 Series
Your Daavlin 1 Series features a built-in power meter that measures energy output. Once a dose
and backup time have been selected the unit will use the information gathered by the sensor to
determine the exact amount of time that each treatment will last. The dose is entered in
milliJoules for UVB and Joules for UVA.
The output of fluorescent lamps varies with age, use and other factors such as room temperature.
Integrated Dosimetry measures for such variations and then integrates them into the dose
treatment time. This is a very effective way to ensure the precision of each treatment.
