Adjusting USB Cable Length
Scholar HD has an integrated cable management system in its base. This allows
the user to adjust the USB cable to precisely the correct length, so there is no
excess cable around the laptop or PC it is being used with.
The maximum length available is 110cm or 43 inches.
Increasing the cable length
1. Ensure the Scholar HD is in its folded configuration and unplugged.
2. Turn the Scholar HD camera over so that the base is facing upwards.
3. At the rear of the base, the USB cable exists out of a small hole in the middle.
Feed approximately 4 cm of the cable inwards through the exit hole to help
loosen the cable.
4. Trace the cable around the two cable grippers and carefully unwind the
additional length of cable that is required.
5. Finally, carefully pull the unwound cable through the exit hole and ensure
the cable has been pulled tightly so that the cable does not poke through
the bottom of the base and cause the Scholar HD to be uneven.
IMPORTANT:
USB extension cables will not work with Readit Scholar HD. If a longer cable
is required, then a mains powered USB 2.0 or above hub must be used.

Positioning Scholar HD for use
Remove Scholar HD from its rucksack and place it on a flat surface. When doing
so, try and ensure that it’s not directly underneath any bright lighting, as this can
affect its accuracy, especially when reading glossy documents.
Unfolding Scholar HD camera
Getting Scholar HD ready for use takes just a few seconds and a few easy steps.
1).
Firstly, place the fingertips of
one hand under the crossbar on
the base and with your other
hand, grasp the centre of the
cross bar and lift it upwards. A
locking pin will click into position
to hold the arms upright once
you have moved it far enough
(around 65 degrees).
2).
With one hand on the base, using
your other hand, grasp one of the
two bars between the camera
head and the crossbar and rotate
it upwards 180 degrees until it
stops and is in line with the main
bars. A locking pin will click into
position once you have moved it
far enough.

3).
With the main stand in position,
tilt the camera head downwards
towards the desk until it stops
or is parallel with the desk. As
the camera head lowers down,
it should locate itself
automatically so that it is
square. This will ensure it is in
exactly the right position for
photographing your documents.
4).
Pictured is the wedge shaped
guide in the camera head that
locates onto the wedge shaped
guide on the camera stand as
the Scholar HD camera head is
titled downwards into the
capturing position.

5).
The whole unfolding process
should only take 10 seconds.
Once unfolded, your Readit
Scholar HD will look like this:

Folding Readit Scholar for transport
To fold Scholar HD for transport, practically the exact opposite method is
required, plus to buttons must be pressed to release two locking pins on the left
hand side of the stand.
WARNING:
Always ensure the camera lens has fully retracted before transporting. This
is done by exiting the Readit software, pressing the on / off button or
unplugging it. Failure to do so may lead to camera damage and is not
covered by warranty.
1).
Firstly ensure the camera is facing
downwards, (in the standard picture
taking position) and with your left
hand, push and hold the top release
button inwards. It’s on the left hand
side of the crossbar, facing away from
you). With the release button fully
depressed, gently lower the top part of
the stand downwards 180 degrees with
your other hand until it stops.
2).
Next, grasp the crossbar with
your right hand and then press
in the bottom release button,
(located on the left hand side of
the base of the stand). With it
depressed, gently lower the
stand downwards until it is
resting flat on the base. Finally,
Ensure the camera head is also
pushed flat to the base.

Plugging In
With Scholar HD unfolded, you can plug Scholar HD in to your PC or laptop. One
USB 2.0 port is required. Below is a picture of typical USB ports found on a laptop
computer:

USB connector (for most computers)
USB Ports
IMPORTANT:
Some computers have their USB ports fitted the other way up!
USB connectors will only plug into USB sockets one way round. They do not
require much force, so take great care when inserting them into a socket.
Forcing a USB connector into its socket the wrong way round will break the
socket and or the connector. This is not covered by warranty.
