Instructions
CAUTION: Prior to using the DermLite DL3, read these instructions and
keep them in a safe place for future reference.
CAUTION: United States Federal Law restricts this device to sale by or
on the order of a physician.
CAUTION: The DermLite DL3 is designed for external examination only.
DermLite DL3 is a camera-compatible pocket dermatoscope designed to
view skin lesions with high magnification and clarity.
Two sets of white LEDs (light emitting diodes) can be activated indepen-
dently; one set of LEDs provides cross-polarized light (by canceling the
reflected light from the skin), whereas the other set of LEDs provides
non-polarized light for traditional immersion fluid dermoscopy.
A high quality, four-element, 25 mm, 10x lens with superb color cor-
rection and reduced image distortion produces an image rich in surface
detail.
To facilitate the use of immersion fluids, and allow for fixed digital imag-
ing, the unit is equipped with a retractable faceplate spacer.
Directions for Use
CAUTION: Do not look directly into the bright LED light. Patients must
close their eyes during facial examinations.
IMPORTANT: Before initial use, please charge the internal lithium ion
battery for a minimum of 4 hours using the charging base provided. See
“Charging” for details.
Hold your DermLite DL3 so that the LEDs are aimed in the direction of
the lesion to be examined. Place the device approximately 1” (~25mm)
from the skin. Push and hold the power button (A) at the right side of the
unit for approximately 1 second to turn on the cross-polarized mode. A
quick tap of the button enables the non-polarized mode for immer-
sion fluid dermoscopy, another tap toggles back to the cross-polarized
illumination.
Look through the lens with your eye placed about 1 to 4” (25-100 mm)
above your DermLite. Move the device closer or further away from the
skin to obtain the desired image focus. For dermoscopy with skin con-
tact, or for camera use, rotate the Focus Dial (B) to the left or right. The
position “0” indicates the ideal distance for photography. To turn off your
DermLite DL3, push & hold the power button for approx. 1 sec.
CAUTION: If your DermLite is used for oil immersion imaging, place the
oil only on the skin and then place the extended faceplate spacer on top
of the oil. Do not allow oil to contact the charging contacts or battery
compartment.
Removing the Spacer
Unscrew the Retaining Ring (B1) and rotate the Focus Dial (B) until the
Spacer (B2) drops.
To re-attach the Spacer, slip its three pins through the three notches (D)
and gently rotate the Focus Dial until the Spacer is being pulled back in.
Reattach the Retaining Ring.
Eyepiece
To reduce internal reflections and improve the contrast of the image,
attach the optional eyepiece onto the 28mm thread (E).
Camera Use
To enable you to attach your DermLite DL3 to a camera, the device is
equipped with a 28 mm thread (E). A simple ring adapter (such as a
28-37 mm stepping ring) may be all that is required to adapt the device
to your camera of choice, although many cameras require a special
adapter made by the camera manufacturer or a photography supply
company. Prior to taking images, wipe the Faceplate (F) clean and extend
the Spacer to the “0” position. Generally, good images may be obtained
by setting your camera to automatic or “P” mode, activating the “macro”
function, and deactivating the flash. Please contact 3Gen or your camera
dealer for more information.
Charging
Prior to using the DermLite, insert the 110V-220V power plug into an
electrical outlet and the other end into the back of the charging base.
Set the base on a level surface. Place the DermLite onto the base, and
the “3” will illuminate red to indicate that the DermLite DL3 is being
charged. When the lithium battery is fully charged and either in its base
or outside its base and powered on, the “3” is green and the device will
allow up to 2 hours of continuous operation, or enough power for imag-
ing approximately 600 lesions at 30 seconds per examination. If less than
25% battery life remains, the “3” will turn orange.
After approximately 1,000 charges, the battery’s capacity will diminish
and the battery may need to be replaced. To remove the battery, slide
the rubber handle (G) back and completely off the device. Disconnect the
small white battery plug and remove the battery. Insert a new battery
and reconnect the battery plug. Slide the rubber handle securely onto
the device.
CAUTION: Your DermLite DL3 uses a special lithium battery, which can
only be purchased from 3Gen or from an authorized 3Gen dealer. Do
not under any circumstances use another battery other than the one
designed for this unit. Doing so could result in damage to the unit. Also,
do not under any circumstances use another charger other than the one
supplied with the unit.
Using the Lanyard
CAUTION: Lanyards pose a strangulation risk. Use with caution.
Run the short, thin portion string through the eyelet (H) located at the
end of the device. Feed the other end of the lanyard through the loop
made by the thin string (I). Separate the DermLite from the lanyard by
squeezing the snap connector (J).

bleshooting information. If your DermLite requires servicing, please go

with Isopropyl alcohol (70% vol.). Do not use alcohol or disinfectants in
the optical areas of the unit. Do not use abrasive material on any part of
the equipment or immerse the device in liquid. Do not autoclave.
Cleaning the Lens and the Polarizers
The lens and the polarizing filters should be treated as high quality pho-
tographic equipment and should be cleaned with standard lens cleaning
equipment and protected from harmful chemicals.
