The battery is partially charged by the manufacturer.
We recommend charging before rst use.
Best practice is to keep your battery charged at more than
30%. Partial charges don’t harm your battery.
When your battery needs charging, the charge indicator
will start to blink. Charge the unit at this point.
To charge, attach the charger lead to the charger port.
The charge indicator (red light) will come on. When the
battery is fully charged, the charge indicator will light
green. We recommend disconnecting the unit at this point,
to maximize battery life.
When your battery is reaching the end of its natural life,
after about 500 charges, you will nd it will need to be
charged more frequently. When this starts to limit your
working time, it is time to have the battery replaced in the
control unit. Your ExamVision dealer will be able to arrange
this procedure.
The working time of your battery varies with light intensity.
The highest setting can give you more than 12 hours
continuous use.

Connecting to your loupe
To attach your Essential
Alpha to your loupe, turn
your loupe upside down on
a stable surface in front of
you. There are two mounting
points on the bridge of the
loupe frame. Position the
light framepart under the
mounting points so the
holes line up, and gently
screw the light in place, just
hand tight. Be careful not to
let the screwdriver slip.

Follow these instructions
to set up your light correctly
Ensure your LED light
is centered correctly by
focusing on an object and
closing rst one eye then
the other.
If you nd that the light is
more to one side of your
vision, loosen the screws
under the framepart
slightly and adjust until the
light is perfectly centered
with your vision. Tighten
the screws to keep the
light in place.

Using your Essential Alpha control unit
Turn the button to turn the light on and off. Rotate to alter
light intensity. The blue power indicator will show the unit is
switched on, and how much charge remains in the battery.
Using the belt clip
Slide the belt clip over a belt or pocket. Place the control
unit so the cable does not catch on clothing or tools.
7
Using the curing lter
Attach the curing lter by stretching the black silicon band
over the lamp, orienting the lter so it is easy to flip it up
out of the way when not required.
Cable direction
The cable can be attached to the right or left loupe temple.
Replacing your cable
If your cable becomes damaged, your ExamVision dealer
can arrange repair of your light.
Cleaning
Cleaning – clean with a soft cloth, and ensure all jacks
and connections are free of dust and dirt.
Water resistance
– your light and control unit are not
designed to be immersed in water. Clean off any splashes
immediately to avoid damaging your unit.
Disinfection
– use only alcohol-free disinfection products,
such as ExamVision Disinfectant Wipes (available from your
ExamVision dealer). DO NOT use alcohol-based products,
ultrasonic cleaners, autoclave or other chemical disinfection.
A wet wipe could discharge the battery, if the wipe touches
both contact points on the battery at the same time.
