About This Manual

console are explained in “CCTV Mode” on page 10 and “OCR Mode” on page 17.
Some features on Merlin elite Pro are accessed by pressing a button or a combination of
buttons. When steps refer to a button on the device or its control console, the button
name is capitalized, such as the Color Mode button. When steps refer to text displayed
on the Merlin elite Pro screen, the text is bold. For example, the Product Settings menu
is in boldface, as well as the Extended Zoom option on that menu.
Instructions for going to a menu option are given using right angle brackets >. When you
see, Settings > Audio > Volume, for example, you use the Zoom wheel to select Settings
and press the Find button, then do the same for Audio, then again for Volume.
To view a quick reference of the control console buttons, do the following:
1. If your screen does not show a full-screen live image, go to CCTV mode by pressing
the center button on the front panel under the LCD screen.
2. Go to the main menu by pressing up on the Color Mode
button and pressing the Find button on the control console.

Control Console
The control console and its cover are required to use Merlin elite Pro. Familiarizing
yourself with the console will be helpful because how you configure the console will
affect your user experience.
The control console for Merlin elite Pro has an intelligent design that allows you to
customize features on demand and switch between “Basic” and “Advanced” modes.
When the cover is on the control console, you are in Basic mode. When the cover is off,
you are in Advanced mode. If you add or remove the cover, Merlin elite Pro immediately
detects the change and modifies available features.
Basic Controls
Beginners may be more comfortable with the
Basic control console, whether in CCTV or OCR
mode. With the cover on the console, fewer
features are available but the product is easier
to use. You still have access to the essential
features necessary to magnify an object or
perform an OCR scan.

Enhanced Vision
Merlin elite Pro User Manual 7
Advanced Controls
When you remove the control console cover, you are in Advanced mode. This enables
features such as the Library option, which is otherwise grayed out in the menu, as well
as saving, recall, OCR zone identifiers, and OCR line navigation.
Modes of Operation
Merlin elite Pro has two main modes of operation that can be toggled by pressing the
center button on the front panel under the LCD screen: CCTV mode and OCR mode.

8 Merlin elite Pro User Manual
CCTV is the default mode that will display immediately
after you power on the device. This high-quality live
image is designed for real-time 1080p high definition
viewing.
OCR mode is available to assist you in reading documents
by automatically scanning documents for OCR, then
reading the text using text to speech (TTS).
Turning Off the Device
You can either put your device into standby or shut it down. If you are going to be gone a
short time, consider standby, but when you are done for the day, consider a shutdown.
Standby
When your Merlin elite Pro is not in use you may want to place it into standby. Placing
your device into standby mode saves power and allows a quicker return to normal
operation than compared to a full shutdown.
To place your device into standby, briefly press the Power button on the front panel. The
LCD display dims and the front panel LCD indicator lights blink several times before
turning off.
To resume, press the Power button again. It takes approximately 15-20 seconds until the
device is ready to use after it has been in standby.

Merlin elite Pro User Manual 9
Shut Down
When your Merlin elite Pro is not in use, you may want to power it off. Placing your
device into a full shutdown saves the most power but takes a little longer to start up
when compared with standby.
To perform a full shutdown, hold down the Power button on the front panel for five
seconds. A message indicates you are entering into the shutdown sequence and asks
you to wait until the status LEDs are no longer illuminated and the message is no longer
displayed before removing your Merlin elite Pro from the power source. Shutdown takes
approximately 10 seconds.
Warning: To maximize the life of your product, do not
disconnect Merlin elite Pro from power while in standby or
during the shutdown sequence. Wait until the shutdown
sequence has completed to disconnect your device.

CCTV Mode
This mode is used for reading, writing, and enjoying crafts or hobbies. Merlin elite Pro
can slide targets freely, up, down, left, or right, using the specially designed X/Y table
mechanism. Adjust the magnification level via the Zoom wheel to a size that suits your
reading preference and then smoothly glide your material left or right.

The camera is attached to a stand, lighting system, adjustable monitor, and movable X/Y
table. The LCD screen is mounted onto a bracket that allows you to tilt and adjust the

CCTV Basic Control Console
Basic mode is when the cover is on the control console. You do not have access to the
Library button and other features, which are described in “Advanced Mode.”
You can take the cover off or put it back on at any time. With the cover on, the OCR
button configuration changes to a more basic format but still provides the essential
features needed for a document scan.
Some features on Merlin elite Pro are accessed through a combination of buttons on
your control console, meaning that the buttons should be pressed at the same time. For
example, you might be instructed to press up on the Color Mode button while pressing
the Find button. If neither the front panel nor control console is specified, then the
button is available on either one.
The Basic controls are shown on the previous page and described in the following table.
Label Name Description

release the button, it returns to your previous magnification
level.
