You can increase or decrease the size (magnification) of the image 

by using the SIZE dial located at the center of the Merlin VGA 

control panel (see Figure 1).

There are sixteen levels of magnification 

available on the Merlin VGA.

•  To increase the size of the image, turn 

the dial clockwise, or to the right.

• To decrease the size of the image, turn 

the dial counterclockwise, or to the left.

The size you've selected will be displayed 

in the upper left corner of your monitor 
(see Figure 2).

When Merlin VGA is first turned on, it is automatically set on 

Auto 

Focus

. This is the most convenient setting for everyday activities, 

such as reading anything from a single page to a thick book, 

reading a prescription bottle, or working with arts and crafts.

Alternately,

 Focus lock

 allows you to maintain focus on a specific 

object at a fixed distance, such as writing. Merlin VGA's Intelligent 

Focus Lock feature will automatically refocus on the object you are 

viewing after changing magnification size.

to Use Focus lock for Writing

1. Place your note paper, stationery, checkbook 

or other writing material on the X-Y table.

2. Press the [LOCK] button on the control panel. 

The letters “FL” will appear and remain in the 

upper left corner of the monitor. In this mode, 

the Merlin VGA will now keep your writing in 

focus, rather than your hand when it comes into 

the camera’s frame.

If you change magnification sizes, Intelligent 

Focus Lock will automatically refocus on the 

desired object or page.

3. To return to auto focus mode, press the 

[LOCK] button again. The letters “AF” will 

appear in the upper left corner of the monitor.
