Installation
The Liberty Scholar 2 is supplied the following components:
oMain Unit
oEX2 Distance Camera
oPower supply adapter
oMains cable
oCarry case
When setting up, it is important to choose your workplace carefully to avoid an
uncomfortable or awkward position. The monitor should be below eye level to
avoid strain.
Remove the Liberty Scholar 2 main unit from its case and place on the
work surface.
Depress both handle release buttons and rotate the handle by two clicks
to allow you to look onto or slightly down on the display.
IMPORTANT! If the handle is set back too far, the camera will not be
able to focus on the reading material at high levels of zoom.
The camera can focus on material up to about 25mm / 1-inch tall. If
you wish to look at objects taller than this, tilt the camera slightly and
move the object appropriately to increase the distance between the
object and the camera.

Page 4
Rotate the slide bar out of the stowed position and slide the bar outward.
Connect the Ex2 Camera firmly onto the slide bar and plug the camera
lead into the topmost socket at the right hand side of the main unit
As the unit is supplied with the battery partially charged, we recommend
that you initially operate the Liberty Scholar 2 from the power supply.
Plug the power supply into a wall socket and insert the connector into the
right hand side of the unit above the Camera cable.

Page 5
Power up the Liberty Scholar 2 by pressing the red power button (the
right-most button on the front panel).
When you aim the distance camera at anything of interest you should see
the magnified image on the screen.

Reading Lens
The reading lens should be flipped up and onto the back of the camera
when viewing into the distance. It should be placed firmly down and
over the camera lens when looking at closer items.
There is a mirror mode available. If the camera is looking out
horizontally and the reading lens is down over the camera, it will
automatically mirror the image. In this mode the Liberty Scholar can
operate in a similar manner to a magnifying mirror.
Mode Button
Press the small round button for overview mode or to freeze the
image. The operation performed depends on how the button function
has been programmed. Refer below to the next section –“Menu”.
Zoom-In Button
Press to zoom in (magnify). At high zoom levels, the camera cannot
focus on objects closer than 1 meter with the reading lens up or closer
than 16cm with the reading lens in place. Objects closer than this may
or may not focus correctly depending on the level of zoom –this is
not a fault in the camera.
Zoom-Out Button
Press to Zoom out.
Camera Customization Menu
Certain aspects of the camera’s operation can be customized through
its menu. The camera’s menu can be accessed by keeping the
Function (top) button pressed for three seconds. Move up or down
through the menu by using the up (zoom-in) or down (zoom-out)
buttons. Press the Function button to select the function.

focus without the user’s intervention.

Page 10
Push To Focus
When selected the camera will only adjust the focus position
when Zoom In or Zoom Out buttons are pressed.
Orientation
By default the camera is orientated away from the user. This
orientation makes it easier to flip up for distance viewing and down
for close-up work. But the camera can also be orientated towards the
user, reducing the distance to the user has to stretch when writing.
In the orientation menu you can choose from Orient Away or Orient
Near.

corrupt the saved settings.

Battery
The Liberty Scholar 2 contains a rechargeable battery that can provide power
for mobile use. A low battery warning icon will appear briefly on the screen, in
addition to warning beeps, when the battery is running low or when powered-
on with a dying battery. The Liberty Scholar 2 will only power up very
briefly, or not at all, when the battery is dead.
Low Battery Warning Power Adapter Detected
The battery will power the unit for over 5 hours depending on the backlight
brightness. So, to extend battery time, use the lowest backlight level you can
comfortably read with.
A full recharge takes approximately 5 hours. The Liberty Scholar 2 will
charge when the power cable is inserted; it does not have to be switched on and
it will also recharge during normal use with the power cable attached. The
battery cannot “overcharge” and does not have to be fully discharged before
recharging. An icon will appear briefly on the screen when the power cable is
attached, showing that the battery is now being charged.
Maintenance
When the Liberty Scholar 2 becomes dirty it can be cleaned with a damp cloth
and mild detergent. Do not use solvents or abrasive cleaning agents as they
can mark the display area. The camera’s lens and the reading lens should be
cleaned with a clean, dry cloth.
If the tilting of the camera becomes too loose with use, we have supplied an
allen key with this manual to enable you to tighten the movement. Do not over
tighten the screw!
