DermLite DL3N is a smartphone-compat-
ible pocket dermatoscope designed to
view skin lesions using cross-polarized or
non-polarized light and high magnification
and clarity.
A high-quality 10x lens with superb color
correction and reduced image distortion
produces an image rich in surface detail.
Hold your DermLite DL3N so that the
LEDs are aimed in the direction of the
lesion to be examined. Place the device
approximately 25 mm (1") from the skin.
Push and hold the power button (A1)
for approximately 1 second to activate
cross-polarized mode. A quick tap of the
button toggles between polarized and
non-polarized modes. The additional Pig-
mentBoost® illumination may be activated
via the left button (A2).
Look through the lens with your eye
placed about 25-100 mm (1-4") above the
lens. Move the device closer or further
away from the skin to focus. For dermos-
copy with skin contact, extend the spacer
by rotating the Focus Dial (B). To turn off
your DermLite, push & hold the power
button for about 1 second.
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 Retain-
ing Ring.
Eyepiece
To reduce internal reflections and improve
the contrast of the image, attach the op-
tional eyepiece onto the 28mm thread (E).
Photography
DermLite adapters for mobile devices and
cameras (sold separately) are designed to
attach to the 28 mm thread (E). To accept
DermLite magnetic adapters, attach the
included steel ring to the 28 mm thread.
Prior to taking images, wipe the Faceplate
(F) clean and extend the Spacer to the "0"
position.
Battery and Charging
CAUTION: This device uses a special
3.7V 1250 mAh lithium ion battery, which
can only be purchased from DermLite or
from an authorized DermLite dealer. Do
not under any circumstances use another
battery other than the one designed for
this unit.
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" illuminates red to indi-
cate charging. When fully charged, the "3"
turns green and the device will allow up
to 2 hours of continuous operation. When
less than 25% battery life remains, the "3"
turns orange.
The battery's capacity diminishes after
years of use. To replace the battery, slide
the rubber handle (G) back and complete-
ly 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.
