Instructions

CAUTION: Prior to using the DermLite, read these instructions and

keep them in a safe place for future reference.

CAUTION: United States Federal Law restricts this device to sale

by or on the order of a physician.

CAUTION: The DermLite is designed for external examination only.

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

CAUTION: Do not look directly into the bright LED light. Patients

must close their eyes during facial examinations.

IMPORTANT: 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).

CAUTION: 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).

CAUTION: 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 Direc-

tive. 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 dimin-

ish 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.

CAUTION: 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.

Troubleshooting

Please check our website (www.DermLite.com) for the most cur-

rent troubleshooting information.

If you need to return the DermLite II PRO HR to 3Gen for servicing,

please call 3Gen prior to returning the device, and a unique Return

Merchandise Number (RMA) will be issued to you.

No Light

Fully recharge the battery and check again. If the condition persists,

send the unit to 3Gen for evaluation and/or repair.

Weak Lighting Recharge the battery.

LED Fails

The LEDs used in the DermLite II PRO HR are designed to last over

100,000 hours. If any of the 32 LEDs fail, contact 3Gen for repair.

Mechanical Malfunction

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.
