Instructions
CAUTION: Prior to using this Derm-
Lite, read these instructions and
keep them in a safe place for future
reference. United States Federal Law
restricts this device to sale by or on
the order of a physician. This DermLite
is designed for external examination
only.
DermLite GL is a smartphone-compat-
ible polarized light examination device
with 6x and 1.4x magnification.
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
supplied USB charging cable. See
"Battery & Charging" for details.
Hold your DermLite GL so that the
LEDs are aimed at the skin. Posi-
tion the device ~25-50mm above the
skin and push the Power button (P) to
activate one group of LEDs. To activate
the other group of LEDs for the other
magnification lens, simply push the
Power button (P) again. Look through
the lens with your eye 25-50mm above
your DermLite. Move the device closer
or farther away from the skin to obtain
the desired image focus.
To turn off your DermLite, push and
hold the Power button (P) for about one
second; the unit turns off automatically
after 3 minutes. To help you approxi-
mate the size of a skin lesion, the de-
vice has a 40mm scale (MM) debossed
into its housing.
Cap
To protect the optical areas after use,
slide the cap (C) over your unit. During
use, the cap can be attached over the
other tail end of your DermLite.
Smartphone/Camera Use
Your DermLite GL may be attached to
many smartphones using DermLite
adapters (sold separately). For best
results, prior to taking photos using
the higher (6x) magnification, snap the
Spacer (S) onto your unit, ensuring
alignment with the notch (N).
Battery & Charging
CAUTION: Your DermLite uses a
special lithium 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.
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 DermLite, connect the
supplied cable to the Charging Port
(CP) and any available USB port. When
fully charged, the device will allow
approximately 2 hours of continuous
operation. After years of use, you may
wish to replace the battery, which is
only available from 3Gen or an autho-
rized 3Gen dealer.
To change the battery, contact 3Gen or
your local 3Gen dealer.
