The best working distance when using the doctors
eyes ring light is 16 - 21,5 cm. This distance might
change according to the close-up lens you use.

The Power & Light Conroller PLC-4
Charging the Controller
When charging the controller, only use the power
unit provided by doctorseyes. Connect the power
unit to the socket on the back of the controller.
The blinking loading symbol shows the loading sta-
tus even when the controller is turned off. When the
controller is fully charged, the loading symbol chan-
ges from red to green. The red low battery symbol
disappears after charging.
When the PLC4 is fully charged the blinking charging
symbol will disappear. The elements of the battery
will appear on the display. It will take approx. 3 hours
to charge but you can stop charging at any time. The
battery has no memory effect.
Important: You can have the battery connected to
power constantly due to trickle charge. (Firmware
version >2.3)
Low Discharge Technology
Staring at version 32 the PLC-4 is equipped with low
discharge technology. Even if you don*t use the con-
troller for 6 months the batterys will still have 90% of
it‘s capacity.After 12 months it will still have 80% of
it‘s capacity.

Working with the PLC 4 Professional
On / Off:
The PLC-4 can be activated with the button on the
top right side and the blue display will be illuminated.
Brightness control:
The brightness can be adjusted in 13 steps with “+”
and “-” buttons on the right side. The current setting
will be displayed via a bar chart and when reaching
the brightest level the word “ultrabright” will be dis-
played.
Switching of LED segments:
You can activate or deactivate segments on the Ring
and Winglights. This gives the user a maximum of
light situations.
The 3 pairs of buttons on the left side allows you
control of the led segments. The activated segments
will be displayed
Every Setting is also displayed with a specic num-
ber. When reaching the last setting the presets start
from the beginning. The presets can be selected by
pressing the buttons accordingly. When pressing the
button longer than 1 sec., you step from one setting
to the next more rapidly. This will speed up the pro-
cess of nding the desired settings. You only need to
look on the camera’s display.
Tip: When making shots of the front teeth then it is
more efcient using light supplied by the the wings
and deactivating segments from the ring light.
Note: When making front teeth shots it is adviseable
to switch off the Ring Light using only ilumination
supplied by the Wing Lights.

size of area where the camera will focus on.
6) A-Mode: Improving depth of focus
Adjust depth of focus In the P-mode the Canon G15
automatically sets the shutter speed and aperture
with acceptable depth of focus. If desired, you can
in uence the depth of focus by manually setting the
camera’s aperture.Turn the mode dial to the A-mode.
The display will show an A in the upper right corner.
To select aperture value, Move the front Control Dial
The higher the number, the smaller the aperture,
thus more depth of focus. The aperture you select
also depends on whether the zoom is set more to the
W or T side. One can shoot pictures without using a
tripod up to a shutter speed of 1/60 of a second.
To change aperture just press the button as shown
on the picture until the setting for the aperture is
selected and change value with the Control Dial to 8
(maximum value for this camera).
Note: We have set up your camera with the aperture
8 preselected on Custom mode C1. Just turn menu
dial until C1 stops at the yellow glowing mark .
7) Changing ISO values
In case the light might not be suf cient then raise the
ISO speed value to prevent getting badly focussed
pictures. If you choose too high an ISO speed
then the picture quality will decrease.When using a
doctorseyes lighting system you should always have
enough light. If not kindly check the brightness con-
trol on the Power & Light Controller

nger on the button slightly pressed down holding

customizable menues. Even adjustments like zoom
position and custum white balance settings can be
recalled this way.
2) Disabling ash
Press on the ash button (see picture) until the „ash
disabled“ symbol appears on the display. This sym-
bol will also remind you anytime that the ash has
been disabled.
3) Custom white balance setting
The light supplied by our ring light is equivalent to a
cloudy light situation. In order to reproduce the right
tooth colours in your practice you should perform
a custom white balance reading with the camera.
Some light situations are too difcult for the AWB
(auto white balance) setting to interpret correctly.
Adjusting the Tone (White Balance):
1) Switch on Ring Light
2) Press FUNC./SET Button and step on to WB
Menu with the direction buttons
3) Select Custom White Balance 1 in the
horizontal Menue in the right bottom corner.
4) Point the camera (with the lighting system turned
on) on a white sheet of paper and press the
button.
5) The camera will take a picture and it will use the
„white“ as a reference for further takes. Now press
the MENU button. You will see a color square.
Move the point two pixels in direction M and one
pixel in direction B. Now press MENU to get back.
Chose My Colors menu below WB menu and
select „Lighter Skin Tone“ to get the best dental
results.
Note: When using the doctorseyes Ring Lights you
should make the white balance measurement using
the same lighting conditions as you will when making
dental shots of your patients.

The doctorseyes diffusors
When using the ring light for smile shots, the optio-
nal diffusor helps to smoothly spread the light output.
This prevents re ections and the shading effect
(dead spot) in between the leds. Also the soft light
gives a very professional illuminated image. The
diffusers are avaliable for all ring- and wing lights.
