result.
Do not use this device during magnetic resonance imaging (MRI) or in an MRI environment.
IMPORTANT: Before initial use, please charge the internal lithium ion battery. See “Battery
and Charging” for details.
DermLite DL5 is a smartphone-compatible pocket dermatoscope with 10x magnication for
visualizing skin structures using variable polarized light and UV illumination.
Hold your DermLite DL5, with the LEDs aimed in the direction of the lesion to be examined,
approximately 12 mm above the skin. Push the main button (M) to turn on the device in
cross-polarized mode. Look through the lens and move the device closer or farther away
from the skin to focus the image. For dermoscopy with skin contact, rotate the Focus Dial
(FD) to extend the Spacer (S) and focus the image. Push and hold the main button (M) for
about 1 second to turn o the device. To save power, the unit automatically turns o after
3 minutes.
Variable Polarization
Tap the main button (M) to toggle between cross-polarized and non-polarized illumination.
Turn the main button to move through the range of 9 polarization settings, from cross-polar-
ized via non-polarized to parallel-polarized light. The indicator strip (IS) reects the current
polarization status, whereas “X” marks cross-polarized, “0” represents non-polarized, and
“=” stands for parallel polarization.
PigmentBoost®
While white light is active, tap (PB) to activate the orange-colored PigmentBoost lighting
in addition to white light. The indicator LED next to the PB button (PB) will illuminate. Tap
again to deactivate.
UV Mode
To visualize uorescing structures, tap the UV button (UV) to activate LEDs with a wave-
length of 365 nm. The indicator LED next to the UV button (UV) will illuminate. Tap the
button again to return to the previously selected white-light mode.
Torch
To illuminate larger skin areas or body cavities, tap the torch button (T) to activate an
ultra-bright white non-polarized LED. Turn the main button (M) to adjust torch brightness.
Dermoscopic Brightness Adjustment
To adjust the brightness of the white dermoscopic LEDs, hold the torch button (T) and si-
multaneously turn the main button (M). While in UV or PigmentBoost mode, push & hold the
UV (or PB) button and turn the main button to adjust the respective brightness. The indicator
bar (IB) reects the current brightness level during the adjustment.
Eyepiece
For optimal viewing ax the included magnetic eyepiece (EP) at the extension ring (ER).
Smartphone Dermoscopy
For dermoscopy using a smartphone or tablet, securely fasten the MagnetiConnect clamp
adapter (MCC) to your mobile device, ensuring concentric alignment with its main camera.
Attach your DL5 to the MCC ring. Prior to taking images, extend the spacer (S) to the “0”
position, and wipe the glass contact plate (CP) clean.
Removing the Contact Plate
Turn the glass contact plate (CP) counterclockwise to detach, turn it clockwise to reattach.
Ruler
The ruler (R) is magnetically attached to the handle. Press down in the middle of the ruler
and remove it to measure skin lesions.
IceCap®
To support your infection control measures, snap one of the included disposable IceCaps
(IC) over the installed faceplate (FP). To remove and dispose, simply pull it o.
Battery and Charging
CAUTION: This device uses a special 3.7V 3000mAh lithium ion battery, which can only be
purchased from DermLite or from an authorized DermLite dealer. Do not under any circum-
stances 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 corresponding with charge level. When charging is complete, all
four indicator LEDs illuminate. 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 change the battery (B), pull o the dial (D) by
grabbing it at the ngernail notch, unscrew the cover screw (CS) using the tool supplied with
each DL5 replacement battery, and sliding the battery cover (BC) o the device. Disconnect
the small white battery plug (BP) and remove the battery (B). Insert a new battery, reconnect
the battery plug, reattach the battery cover (BC), secure it with the cover screw (CS), and
push the dial (D) in until it snaps into place.
Charging Base
To charge your DL5 using the charging base, attach the smaller (USBC) end of the supplied
USB cable to the power port (PO) on the back of the charging base (CB), and the larger
(USB) end to any IEC 60950-1 compliant (5V) USB charger. Place your DL5 into the
charging base, with the contact plate (CP) facing towards the charging base. The charging
base is equipped with a USB charging port (CP) which may be used to charge your smart-
phone or other DermLite devices. The charging base may also be used for IceCap storage.
