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.
