Chapter 3: Operations

Video signals are susceptible to the effects of long distance cables and for this reason, every 

Emerge EMS receiver includes brightness and sharpness adjustment dials. Additionally, the 

Emerge EMS1000MP-R receivers are also equipped with two extra dials to eliminate the effects 

of color skew within the video image.

The brightness and sharpness adjustments provided on 

every Emerge EMS receiver allow you to compensate for 

any losses incurred within long cable links. These two 

adjustments can be made in any order and independently 

of each other.
When making adjustments it is necessary to have access 

to the Emerge EMS receiver and to be able to view one 

or both connected display screens. Both adjustments, 

sharpness in particular, are made easier when viewing 

high contrast images with vertical edges, such as black 

lines on a white background.

NOTE: Both video outputs are equally affected by your brightness and/or sharpness adjustments. 

To Display a Suitable High Contrast Image 
•  Open a word processor, type the capital letter ‘H’, or 

‘M’ and increase the point size to 72 or higher. For 

best results, the background should be white and the 

character should be black. 

•   A BLACK shadow on the right of the character 

indicates UNDER compensation. 

•   A WHITE shadow on the right of the character 

indicates OVER compensation.

To Adjust Brightness and/or Sharpness 
1.  Carefully insert a small screwdriver into the dial labeled 

 or 

, as appropriate.

2.  Slowly turn the dial clockwise or counterclockwise and observe the effect shown on the 

screen. Withdraw the screwdriver when the displayed image is shown at its optimum clarity.

3.  If necessary, repeat step 2 for the other dial.
