10.0 General Instructions (All Modes of Operation)
10.1 Pre-treatment Preparations
Before starting therapy, show your doctor these instructions. He or she is the final authority for your
treatment, and, depending upon your particular circumstances, may change these directions. Always follow
your physician’s instructions.
The ClearLink Controller will track your treatment data. However, you may want a notebook, or treatment
log in which to record the date, dose and duration of each of your treatments along with any other notes
regarding your treatment or treatment results. (For example, forgot lip balm, put sunscreen on tender area,
etc.)
Note: A free printable treatment log is available for download at www.Daavlin.com.
You will need to purchase lip balm and sunscreen with an SPF (Sun Protective Factor) of at least 30. Ask
your doctor whether or not you should use an alcohol or cream-based sunscreen.
10.2 Special instructions – 4 Series with 20 Lamps Only
If you have a ten-lamp unit, treatments should only be taken from a distance of 9 inches!
Your 4 Series twenty lamp unit has been designed to deliver accurate and effective treatments from two
distinct treatment distances. If you have been prescribed a 20-lamp unit, treatments can be administered
directly on the acrylic’s surface (0 inches) or at a distance of nine inches from the acrylic (9 inches or 22
centimeters).
The intensity or power output of the device will be much greater when treating directly on the acrylic
surface versus treating from nine inches away. For this reason, you must select the desired treatment
distance before administering a treatment. See specific instructions under Running a Treatment.
By selecting the treatment distance, 0 in or 9 in, you aretelling the system how it should calculate thelength
of the treatment based on the distance from the lamps.
10.3 How to Position Yourself
Large Area Treatments: The recommended distance from the lamps for treatment is 9 inches (22
centimeters). We also recommend that you mark that distance on the floor in some manner. Your torso
should not be closer to the lamps than this line. Standing closer to the lamps will cause localized streaking
or burning.
Small Area Treatments at the Acrylic Surface (20 lamp 4 series only): Place the area being treated
directly on the acrylic lamp guard. For best results you should position the area being treated as close as
possible to the center of the fixture.
Note: When treating, be careful to not place too much weight or pressure on the acrylic surface. Excess
pressure can cause the acrylic surface to crack and break.

MNL-00004 [4] Proprietary and Confidential Page 12 of 24
10.4 Unlocking the Device
To prevent unauthorized use, the device will self-lock when left idle
for twenty (20) minutes.
1. Tap the blank screen. The Daavlin logo will appear.
2. Tap the logo. The Lock Screen will appear (unless disabled)
3. Using the keypad, enter the number 7 (unlocking code)
4. Press the Enter key to unlock.
10.5 Common ClearLink™ Functions
The system beeps to signal the end of the treatment and displays the
delivered dose with the elapsed time.
If power goes off during a treatment, the system will track how much of the treatment has elapsed and
will allow the treatment to resume when power is restored.
10.6 Post-Treatment
After a treatment, you may protect any areas that feel sunburned with sunscreen for the next several
treatments or until they appear normal. (Make a note in your notebook.) You should see your physician at
the intervals he or she requests when actively using the unit. Always take the notebook with you when you
see your physician.
10.7 FlexRx™
If your unit was prescribed with FlexRx™, a screen (Figure 7 FlexRx Screen) will tell you how many
exposures remain before you need a refill prescription. See Section Uploading FlexRx™Refill
Prescriptions for refill instructions.

11.0 Guided Mode
11.1 Features of the ClearLinkTM Guided Home-Control System
The ClearLink Guided Home-Control System automatically performs many safety checks on your behalf,
as well as calculating dose increases based on your treatment schedule and how your skin responds to
treatment.
For example, each time you use the device, the ClearLink Controller will check the date of your last
treatment. If you are on schedule, it will automatically proceed. However, if you have missed a treatment
or treatments, the system will adjust accordingly to keep your dose at a safe level. A screen will appear
advising you of the adjustment (See Figure 8 below).
Figure 8
Integrating dosimetry, another feature, uses a built-in sensor to monitor the amount of light energy being
produced by the device. The system then automatically adjusts your treatment time to account for variations
in light energy caused by changes in room temperature or the aging of the lamps.
Finally, before each treatment, the ClearLink Controller will ask about the current condition of your skin,
such as whether or not there is any redness, mild or otherwise. It will use this information to calculate the
next dose. Keep in mind, it is normal to experience some “redness” within 8 – 12 hours of a treatment but
it is typically gone before it is time for the next treatment.

MNL-00004 [4] Proprietary and Confidential Page 14 of 24
11.2 Running a Treatment
Note: The first time you use the device, your dose will automatically appear, based on your doctor’s
prescription. After your first treatment, the screen will display the next scheduled treatment, but will ask if
you experienced any pain or redness after your last treatment. Based on your response, the system will
adjust the treatment according to your prescription.
1. After unlocking the device, the Treatment Screen will appear with the scheduled dose.
2. You will be asked, “Were you in pain or red after your last treatment?”
3. You must choose one of the following responses:
No, or < 24 Hrs (“Not at all, or it was gone in less than 24 hours”)
24 –48 Hrs (“I was in pain or red for 24-48 hours after the treatment”)
> 48 Hrs (“I was in pain or red for more than 48 hours”)
Still red / pain (“I am currently still red or have pain”)
Note: Selection of the “Still red / pain” option will lock the device until one treatment has been skipped.
This prevents treating the skin until the erythema (redness) has resolved.
4. Once you have highlighted your response, press the Enter key.
5. Choose the treatment distance by pressing either the “9 in” button or the “0 in” button (Only for
20 lamp units)

acrylic, as appropriate. See Section Error! Reference source not found. for guidance.
7. Press the Enter key to begin the treatment. A 3 second countdown will begin; the lamps
will turn on and the screen will track your progress. The lamps will shut off when the treatment is
over.
8. To repeat the same dose for exposure to another part of your body, touch the Repeat button.
Note: Repeats will not be available after leaving the treatment screen.
9. To pause an active treatment, press the Pause button. To resume, press the Play button.
To end or cancel an active treatment, first pause the treatment and then press the Cancel button

14.2 Uploading FlexRx™ Refill Prescriptions
When specified by your prescribing physician, Daavlin home phototherapy devices are equipped with
FlexRx exposure limiting software. For each sequence of exposures, the number of available treatments is
reduced by one. A treatment sequence consists of the primary exposure plus up to three repeat exposures,
if needed, for treating other areas of your body.
If the device is equipped with FlexRx, upon “waking up”, the screen will display reminders of how many
exposures are remaining. To ensure there are no interruptions in your therapy, we suggest that you contact
your physician for a “refill” when 5 to 10 exposures remain. Once you are completely out of exposures, the
controller will prompt you to upload a new FlexRx prescription.
To enter a FlexRx refill code, wake the controller from its sleep mode and enter the unlocking code. The
controller will ask you to enter a FlexRx code or you may press the Prescription button to begin.
Tap the screen and enter the code provided by your doctor by pressing the up arrows. Press the Enter
key once you have verified that the code is entered correctly. The controller will then display the number
of exposures that have been uploaded and you can then continue your normal routine.
14.3 Changing or Disabling the Unlocking Code
The unlocking code is a safety feature that prevents someone from accidentally turning on or tampering
with the device. It works just like a key. To remove the unlocking code feature or to change it to a number
that is easier to remember, contact Daavlin’s service department at 1-800-322-8546 for step-by-step
instructions. Hours of operation are Monday through Thursday 7:30am - 8:00pm EST and Friday 8:30am
- 5:00pm EST
14.4 Downloading Treatment History
Your doctor may require that you provide a treatment history file so he or she can monitor your progress.
To download your history files, insert a USB drive into the USB port. Press the “Export Data” button then

14.5 Cleaning/Disinfection
14.5.1 General Cleaning
For general use, use a clean non-abrasive cloth, not paper towels, and a mild cleaning solution
such as Dawn Liquid Dishwashing Soap to gently wipe down the exterior of the device.
14.5.2 Low-Level Disinfection
To reduce micro-organisms on the patient-contacting surfaces, disinfect these surfaces between
uses of the device, including when the same patient has the device for use. For disinfection while
the same patient uses the device, we have tested several cleaners that do not degrade the Acrylic
and can be seen in Table 2 Daavlin Tested Cleaners.

1. Thoroughly wipe down the surfaces and allow contact time listed in Table 2 Daavlin Tested
Cleaners.
2. Allow to air dry and inspect for visible contaminants.
3. If contaminants remain repeat until no visible containments remain repeat steps 0 and 2.
14.5.3 High-Level Disinfection
Follow a high-level disinfection protocol between the use of the device on different patients. Use
a high-level disinfectant, such as Steris Corporation’s Resert XL-HLD, and follow the
manufactures guidelines. See also “FDA-Cleared Sterilants and High Level Disinfectants with
General Claims for Processing Reusable Medical and Dental Devices” available at:
https://www.fda.gov/medical-devices/reprocessing-reusable-medical-devices-information-
manufacturers/fda-cleared-sterilants-and-high-level-disinfectants-general-claims-processing-
reusable-medical-and.
We suggest using “Monk” Brand Wipes as they disinfect and will not harm any ultraviolet or light
transmitting surfaces. These wipes are available for purchase from Daavlin. When dusting the unit and the
lamps, we recommend using a feather duster or a similar non-abrasive cleaning device.
Note: Do not clean reflective surfaces with paper towels. They may scratch the surface.
At least once a year, we recommend that you remove the protective acrylic for a more thorough cleaning
of the lamps and reflectors. Refer to Lamp Replacement instructions on how to remove the acrylic and
lamps, as well as other important information on how to ensure that the lamps are safely and correctly

14.6 Calibration (Applicable to Guided and Dosimetric Units Only)
The power output of the device was measured before it left Daavlin’s manufacturing facility. A
“Calibration Output Certificate” is included with the operating manual and contains the device’s factory
measured power output. The certificate for ten (10) lamp units will state the power output of the device at
a distance of nine (9) inches from the acrylic surface of the unit.
Because the 20 lamp 4 Series has been designed to deliver treatments from two specific distances, 0 inches
and 9 inches, the output certificate for 20 lamp units will have two outputs noted in the “Current Value”
box. The higher of the two values corresponds to the “0 inch” setting and the lower of the two corresponds
to the “9 inch” setting.
14.7 Accuracy/Range (Applicable to Guided and Dosimetric Units Only)
The integrating dosimeter will maintain a 5% level of accuracy if the device is calibrated at least annually
or whenever lamps are replaced or every one hundred (100) hours, whichever occurs sooner. The
calibration process involves taking an output reading with a hand-held meter (available for purchase or rent
from Daavlin) and checking it with the output reading from the integrating dosimetry system. Please
contact Daavlin for calibration assistance.
Dose Range:
UVA: 0.1 Joules - 999.9 Joules
UVB: 1 Millijoule - 9999 Millijoules
Accuracy:
+ / - 5%
Calibration:
1 year or every 100 hours of use or upon changing lamps
14.8 Lamp Removal and Replacement
Lamps may need to be replaced due to burnout or because their energy output has decreased to the point
that your treatments may have become excessively long.
DO NOT REPLACE LAMPS INDIVIDUALLY. ALL LAMPS SHOULD BE REPLACED AT THE
SAME TIME TO AVOID UNEVEN TREATMENTS OR BURNS. PLEASE CONTACT THE
DAAVLIN SERVICE DEPARTMENT PRIOR TO REPLACING THE LAMPS TO OBTAIN
IMPORTANT INFORMATION ON HOW THE OUTPUT OF THE UNIT WILL BE AFFECTED
BY THE CHANGE.
Because of differences between brands, always replace lamps with the same brand as originally installed.

14.8.1 Lamp Replacement
1. First, unplug the unit and then remove both feet by unscrewing the four thumb screws on each side.
Once the feet have been removed lay the unit flat on a table with the lamps facing up.
2. Using a Phillips Head screwdriver, remove the four screws on each side of the unit. Once removed,
lift off the top of the device as you would remove the top from a gift box.

3. On each lamp there are two clear plastic clasps that hold the lamps in position. To remove them,
position both thumbs on the top of the clasp and use your index fingers to pull the sides of the clasp
outward until it releases and can be removed.
4. On top of each lamp socket there will be a red button that, when pushed, will allow you to remove
the base of the lamp from its corresponding lamp socket. With one hand, firmly press and hold the
red button down while using your other hand to carefully lift the lamp up and out of the socket.
5. With one hand near the base of the lamp and the other at the opposite end, grasp the lamp and pull
both ends upward at the same time until it clears both clasps and the lamp holder/socket.
6. To replace the lamps in their lamp-holders, press them straight down. A distinctive snapping sound
will be heard which indicates that they are properly seated.
7. Once you have the new lamps in place, reassemble the 4 Series and reset the lamp hours to zero.
14.8.2 Resetting Lamp Hours
When changing lamps, it is important to reset the lamp age to zero so the operating hours of the new lamps
can be tracked. Pleasecontact the Daavlin service department for instructions onresetting the device’s lamp
hours.
