DermLite DL4 is a smartphone-compatible 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.

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 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, simultaneously. 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 illumination, 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, simultaneously. To save power, the unit automatically 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 finger- nail notches.

Battery and Charging
CAUTION: This device uses a special 3.7V 1400mAh lithium ion 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.
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 indi-cator LEDs illuminate. After years of use, you may wish to re-place the battery, which is only available directly from 3Gen or an authorized 3Gen 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 supplied 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).
