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.

The DermLite is a pocket epiluminescence micros-

copy (PELM) device designed to view skin lesions

with high magnification and clarity.

White LED lighting technology combined with a

10x Hastings Triplet lens provides for ideal skin

microscopy. The LED daylight-type light is linearly

polarized, and a second polarizing lens is aligned

to cancel the reflected light from the skin. A high

quality, three-element lens with 10x magnification,

superb color correction, and reduced image distor-

tion is used to image the skin.

Directions for Use (Fig. 1-2)

CAUTION: Do not look directly into the bright LED

Light. Patients must close their eyes during facial

examinations.

Hold the DermLite so that the LEDs are aimed in

the direction of the lesion to be examined. Place the

DermLite approximately 1/2" (~12mm) from the skin

(Fig. 1). If necessary, use your fingers to maintain

optimum spacing. Press the power switch (Fig. 2) at

the side of the unit to activate the LEDs. If you are

right-handed, use your thumb to activate the button

and hold it down as long as you need light. If you

are left-handed, use your forefinger to activate the

power button.

Look through the lens with your eye placed 1/2"(

~12mm) to 1" (~25mm) above the DermLite (Fig. 1).

Move the DermLite closer or further away from the

lesion to obtain the desired image focus.

Replacing the Battery (3)

The long-life 6V Lithium battery provides up to 8

hours of continuous operation, or enough power for

imaging approximately 1200 lesions at 30 seconds

per examination.

To change the battery (Fig. 3), squeeze the cap by

its sides and remove it and the battery. Insert a new

battery of the same type with the contacts facing

forward. Replace the battery cap securely on the

device.

The DermLite uses a 2CR5 Lithium Battery, which

may be purchased from camera stores and other re-

tailers. You may also purchase batteries from 3Gen

at low prices.

Troubleshooting

Please check our website (www.DermLite.com) for

the most current troubleshooting information.

If you need to return the DermLite to 3Gen for ser-

vicing, please call 3Gen prior to returning the device,

and a unique Return Merchandise Number (RMA)

will be issued to you.

No Light

Replace the battery with a new, unused battery and

check again. If the condition persists, send the unit

to 3Gen for evaluation and/or repair.

Weak Lighting

Replace the battery with a new battery (you have ap-

proximately 30 minutes of battery life before the unit

will not function.)

Light Flickers

Remove the battery and check its metal contacts

for dirt or dust. Wipe off any dust and reinsert the

battery. If there are signs of corrosion, discard the

battery and replace it with a new battery. Should you

still encounter flickering, return the DermLite to

3Gen for evaluation and/or repair.

LED Fails

The LEDs used in the DermLite are designed to last

over 100,000 hours. If any of the eight LEDs fail,

return the DermLite to 3Gen for repair.

Care and Maintenance

The DermLite is designed for trouble-free opera-

tion. 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 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.
