Tips for Reading and Writing
Reading with Merlin LCD Plus
• New users of video magnifier systems have a tendency to overmagnify their reading material. Make the type large enough to see it
comfortably, but not so large that it becomes tedious to scan across
a page.
• Use the X-Y table to move reading materials under the camera,
rather than moving the material manually, except small items such
as a checkbook or a business card.
• New users should use two hands when moving the X-Y table for
reading, until they become comfortable using one hand.
Writing with Merlin LCD Plus
• Beginners should start at smaller magnification sizes, and then
increase magnification as they become more comfortable using
Merlin LCD Plus for writing.
• The smaller the magnification size the bigger you tend to write;
the higher the magnification size the smaller you’ll write.
• Use a pen that makes a bold line, such as a heavy point rollerball
pen, a felt-tip marker, or a fine point marker, for easier visibility.
• It might be helpful to use lined paper to more easily find and keep
your place.
• It might be easier to keep your place if you write a few words at a
time, then move the X-Y table and write again, rather than moving
continually as you write.
• Write in either Color, Black and White or Positive viewing modes.

Troubleshooting
1. Merlin LCD Plus Does Not Turn ON
• Make sure the power supply is the proper one for Merlin LCD Plus,
12V output, 3A minimum.
• Make sure the power supply cord is completely plugged into the
outlet.
• Make sure the two parts of the power supply cord are securely
connected.
• Make sure the power supply cord is completely plugged into the DC
12V IN jack in the back of Merlin LCD Plus.
• Check the power strip/surge protector’s ON/OFF switch and circuit
breaker if Merlin LCD Plus is plugged into one.
• Push the POWER button on Merlin LCD Plus’ control panel. A green
light next to the POWER button should turn ON, indicating the
power is ON
(see page 13).
2. Merlin LCD Plus Lights are Not ON
• Check that Merlin LCD Plus is ON. If not, check FAQ 1.
• Check that the light switch (item 16 on page 7) under Merlin LCD
Plus’ control panel is ON.
3. The Foot Switch Does Not Work
• Check that the foot switch cable is properly secured into the part
labeled foot switch.
• Check that a valid computer signal or external video is connected to
the back of Merlin LCD Plus.
• If no computer or external video is connected to Merlin LCD Plus,
you will not be able to use the FOOT SWITCH. An OSD should
warn you once about missing computer signal or external video
source.
4. The Control Box Does Not Work
• Check that the coil cable is properly secured in the control box.
• Check that the coil cable is properly secured in the port labeled
“CONTROL BOX” in the back of Merlin LCD Plus.
• Please refer to Setting Up Merlin LCD Plus with Remote Control
Software or Control Box on page 11 for further details.
38
Troubleshooting
5. The Remote Software Does Not Work
• Check that the software cable and its adapter are properly secured into
a serial port on your computer.
• Check that the software cable is properly secured into the port labeled
“CONTROL BOX” in the back of Merlin LCD Plus.
• Maximize the application software window and make sure the
communication indicator is green. A red indicator indicates a faulty
computer to Merlin LCD Plus communication. The software
automatically detects a proper connection so no configuration is
required.
6. The Image is Blurred or Out of Focus
• Clean the protective glass covering the camera with the non-abrasive
lens cleaning cloth provided with your Merlin LCD Plus.
• Clean the monitor screen with a non-abrasive cloth sprayed with a glass
cleaning solution.
7. X-Y Table Does Not Move Smoothly
• Make sure the locking lever is positioned completely to the left (see
page 28).
8. X-Y Table Does Not Stay in Locked Position
• Make sure the locking lever is all the way to the right and that the
handle pops up into the locking slot (see page 28).
15. Light Bulb Burns Out
Your Merlin LCD Plus comes equipped with two 10,000-hour fluorescent
light bulbs designed to provide years of trouble-free service. However, if
one burns out, contact your place of purchase or Enhanced Vision at
(800)440-9476 for instructions or assistance on replacing the bulb.
16. When Reading Using the X-Y Table, the Video Magnifier Image
Appears Jerky or Not Smooth
• Make sure your computer is set to a 60Hz refresh rate. This will
provide the smoothest picture possible. However, this may cause a
picture flicker sensation. Adjust to the settings that work best for you.
If you have any questions or require technical assistance please call
(800) 440-9476, Monday – Friday from 8 a.m. to 5 p.m. PST.

Warranty
Enhanced Vision
Merlin LCD Plus Video Magnifier Warranty Policy
Enhanced Vision products are designed to give you the highest quality image, convenient features, ease of use
and reliable service. Merlin LCD Plus has been inspected and tested prior to shipping. Our company
stands behind the quality materials, components and workmanship of the Merlin LCD Plus video magnifier.
For these reason we are pleased to offer two warranty options. These options are available when the purchaser
completes the warranty registration form.
Three-year warranty for the Merlin LCD Plus base and the monitor.
This option can be selected on the warranty registration form by the agencies, states, groups,
multi-users, product demonstration sites and the individual purchasers. Enhanced Vision warrants
Merlin LCD Plus against defects in materials and workmanship under normal use for three years from
the date of original purchase. Enhanced Vision, at its option, will at no charge either repair the product
or replace it during the warranty period.
Lifetime warranty for the Merlin LCD Plus base at a one-time cost of $299.00.
Monitor is not included in this option. (Individual purchaser only)
This option can be selected on the warranty registration form and it is only available to the
individual purchaser. Enhanced Vision warrants Merlin LCD Plus base against defects in materials
and workmanship under normal use for the lifetime of the individual purchaser. Enhanced Vision, at its
option, will at no charge either repair the product or replace it during the warranty period.
The Monitor is not covered by the lifetime warranty and it is covered for three years only.
The lifetime warranty is non-transferable and does not apply to groups, multi-users or agencies.
This warranty is not available for International Customers.
On the warranty card the purchaser will be asked to select between the three-year (no-cost) or lifetime
warranty for a one-time fee of $299.00. If lifetime coverage is elected, a $299.00 check made payable
to “Enhanced Vision” will need to be included with the warranty form. The lifetime product
warranty is only valid if the product is registered within 30 days of purchase and a $299.00 check
made payable to “Enhanced Vision” is included with the warranty registration form. If this form
has not been provided, please request one from the local Enhanced Vision representative or call us at
(800)440-9476.
Restrictions
All product purchases need to be registered with Enhanced Vision. Registering Merlin LCD Plus confirms the
right to maximum protection and service of the product warranty. If no selection is made on the warranty
form or payment is missing, the individual purchaser will default to the three-year warranty.
The lifetime warranty is non-transferable and does not apply to groups, multi-users or agencies. It has been
designed for end-consumer / individual purchaser. Agencies, states, group homes, classrooms and demo site
units will receive Enhanced Vision standard three-year product warranty detailed above. Enhanced Vision also
reserves the right to repair or replace any purchasers Merlin LCD Plus with a similar or better product.
43
Warranty
In the case that the end-consumer / original individual resells the Merlin LCD Plus within a THREE year time
period from original purchase date and the product is resold by a recognized manufacturer representative, the
Merlin LCD Plus warranty will default to the balance of what remains of the standard THREE year warranty
(from original purchase date). The lifetime warranty would be void.
Consider the example below:
After one year Mary Smith’s vision deteriorates past using the Merlin LCD Plus to assist her. She
resells the Merlin LCD Plus to a recognized Enhanced Vision manufacturer representative, and he/she
then sells the Merlin LCD Plus to Anne Clark. Anne Clark receives a two-year warranty with the
Merlin LCD Plus (the amount left on a standard THREE year warranty).
Anne will need to complete and submit a warranty registration form, marking the box that she is a
“converted original owner” and provide the serial number for the product.
The THREE-year and optional lifetime product warranty does not cover the following:
1. Defects or damage from misuse, use in other than suggested manner, accident or neglect.
2. Defects or damage from improper operation, maintenance, installation, adjustment, alterations or
modification.
3. Defects from spills of food or liquid.
4. All plastic surfaces and all other externally exposed parts that are scratched or damaged due to
normal use.
5. Damage due to operating Merlin LCD Plus with equipment not supplied by Enhanced Vision.
6. Light bulbs that are not covered under warranty.
7. The Merlin LCD Plus monitor is not included in the lifetime warranty and it is covered for three years.
THERE ARE NO OTHER EXPRESSED OR IMPLIED WARRANTIES FOR THIS PRODUCT.
