DermLite DL4 is a smartphone-compatible
pocket dermatoscope designed to view skin
lesions using cross-polarized or non-polar-
ized 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.
IceCap®
To support your infection control measures,
snap one of the included disposable Ice-
Caps (IC) over the installed faceplate (FP).
To remove and dispose, simply pull it off.
Hold your DermLite DL4, with the LEDs
aimed in the direction of the lesion to be
examined, approximately 25mm (1") above
the skin. Push the power button (P) to turn
on the device or push the two mode buttons
(POL & PB), located at the head, simulta-
neously. Look through the lens and move
the device closer or farther away from the
skin to focus the image. To toggle between
non-polarized mode for immersion fluid
dermoscopy and cross-polarized illumina-
tion, briefly push any button. Push and hold
(POL) for about 1 second to toggle between
two brightness levels.
For dermoscopy with skin contact, rotate
the Focus Dial (FD) to extend the spacer
(S) and focus the image. To turn off your
DermLite, push the power button (P) for
about 1 sec. or push the two mode buttons
(POL & PB), located at the head, simulta-
neously. To save power, the unit automati-
cally turns off after 3 minutes.
Photography
This DermLite may be connected with
mobile devices or cameras using DermLite
magnetic adapters (sold separately) which
attach to the extension ring (ER). Prior to
taking images, wipe the faceplate (FP)
clean and extend the spacer (S) to the "0"
position.
Removing the Faceplate
The faceplate (FP) may be pulled off the
Spacer (S) by grabbing it at the fingernail
notches.
Battery and Charging
CAUTION: This device uses a special 3.7V
1400 mAh lithium ion battery, which can
only be purchased from DermLite or from
an authorized DermLite dealer. Do not un-
der any circumstances use another battery
other than the one designed for this unit.
This device is equipped with a four-level
Charge Indicator (CI). When the unit is
turned on and fully charged, all four LEDs
light up. When less than 75% of battery
life remains, three LEDs are illuminated. If
more than half the battery is drained, two
LEDs are on, while a single LED indicates
that less than 25% of battery capacity
remains. To charge your device, connect
the supplied USB-C to USB cable to the
Charging Port (CP) and any IEC 60950-
1 compliant (5V) USB port. The Charge
Indicator (CI) pulses to indicate charging,
with the number of pulsing LEDs corre-
sponding with charge level. When charging
is complete, all four indicator LEDs illumi-
nate. After years of use, you may wish to
re-place the battery, which is only available
directly from DermLite or an authorized
DermLite dealer.
After hundreds of charges, the battery's
capacity will be reduced to the point where
it may be more convenient to replace
the battery. To remove the battery (BT),
remove the battery cap (BC) by unscrewing
the set screw (SSC) using the wrench sup-
plied with each DL4 replacement battery.
Disconnect the small white battery plug
(BP) and slide the battery (BT) out. Insert a
new battery and reconnect the battery plug.
Replace the battery cap (BC) and secure it
with the set screw (SSC).
