3Gen DermLite II PRO HR - Pocket Epiluminescence Device Manual

Introduction

The DermLite II PRO HR is a pocket epiluminescence microscopy (PELM) device designed to view skin lesions with high magnification and clarity.

A 25mm 10x lens combined with a unique button-activated light intensity settings provides for ideal skin microscopy. A high quality lens with superb color correction and reduced image distortion is used to image the skin. To facilitate the use of immersion fluids, and allow for fixed digital imaging, the unit is equipped with a retractable faceplate spacer.

Directions for Use

Do not look directly into the bright LED light. Patients must close their eyes during facial examinations.

Before initial use, please charge the internal lithium ion battery for a minimum of 4 hours using the charger provided.

Hold the DermLite II 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 the power button (A) at the left side of the unit for 2-3 seconds to activate the LEDs.

Look through the lens with your eye placed 1"( ~25mm) to 4" (~100mm) above the DermLite II. Move the device closer or further away from the lesion to obtain the desired image focus. For oil immersion imaging, or for camera use, rotate the spacer dial (B) so that the white marker is at the 12 o'clock position. For fine focusing within a range of +/- 1mm, simply rotate the dial to the left or right between the 11 and 1 o'clock markers (C).

If the DermLite II PRO HR 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 USB port, DC charging port, or battery compartment

To attach the DermLite II PRO HR to a camera, the device is equipped with a 28mm thread (D). A simple ring adapter (such as a 28-37mm stepping ring) may be required to adapt the device to your camera of choice. Please contact 3Gen or a photographic retailer for more information.

Removable Faceplate (E)
The DermLite II PRO HR is equipped with a removable faceplate. To remove this piece, rotate the spacer dial (B) to extend the spacer, and twist off the small ring in the very front of the spacer.

Light Intensity
A push on the button on the right side labeled "MODE" (F) toggles between two light intensity settings. The first mode activates 16 LEDs, and the second mode gives you twice as much light with the activation of 32 LEDs.

Rechargeable Battery
After a minimum 4-hour initial charge, the lithium-ion battery provides up to 2 hours of continuous operation, or enough power for imaging approximately 600 lesions at 30 seconds per examination. Once the battery is depleted, the unit will automatically shut off, and will need to be recharged. Plug the charging cord into the round DC charging port (G), and the red charging indicator (H) will illuminate. Once the battery is fully charged, the green indicator will light up (I). Optionally, you may use a USB cable to charge the unit via the USB port (J).

When charging with a USB cable, the DermLite II PRO HR must be connected only to the USB port of a computer that complies with the IEC / EN 60950 standard to ensure continued compliance of the product with the European Medical Device Directive. Refer to the operator's manual provided with your computer to ensure that the computer complies with the above standard.

After approximately 1,000 charges, the battery's capacity will diminish and the battery may need to be replaced. To remove the battery door (K), push down on the two ovals (L) with your thumbs and slide the battery door back. Disconnect the small white battery plug, and remove the battery. Insert a new battery and reconnect the battery plug. Replace the battery door securely on the device.

The DermLite II PRO HR uses a special 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. 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.

Please contact 3Gen to arrange for service.

Care and Maintenance

The DermLite II PRO HR is designed for trouble-free operation. There are no adjustments to be made nor is any special servicing required. Never attempt to open the device for any reason.

Cleaning and Sterilization
The DermLite II PRO HR body may be cleaned or disinfected by wiping it 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 photographic equipment and should be cleaned with standard lens cleaning equipment and protected from harmful chemicals.
