2.5.5  Gain Changes

When you get to this menu note that the gain changes will be made as you make them but if you do not wish to 
save the changes you have made, scroll to “R” and push the Menu/Execute switch and select “NO” in the 
“SAVE SETTINGS?” window or do not press the Menu/Execute switch; simply do nothing for 
approximately  12  seconds,  and the system will  return  to  the normal operating mode.

To change the DOWNCONVERTER GAIN:

Push the Menu/Execute switch to get to the gain setting (See Figure 2.5 for the sequence of menu 
options):

G = +25.0

R

Pressing the Up/Down switch will change the gain in 1 or 10 dB steps depending on the cursor location:

G = +15.0

R

By using the horizontal rocker switch the cursor can be moved left or right.  Pressing the Up/Down 
switch will toggle the display digit selected until you have the desired gain. 

G = +15.0

R

NOTE: THE GAIN WILL BE CHANGED AS YOU ADJUST THE NUMBERS. HOWEVER, THE 
VALUE WILL NOT BE STORED UNTIL YOU INDICATE YES IN THE SAVE SETTINGS 
WINDOW.

When the display indicates the value desired you can push the Menu/Execute switch to get to the next 
item:

OTHER?  Y N

R

OR you can scroll to “R” and push the Menu/Execute switch to get to:

SAVE SETTINGS?      Y N

Selecting  Y will save the new settings. Selecting N will revert to the previous settings. Pushing the 
Menu/Execute switch then takes you to this:

F=1450      G=+15.0

Figure 2.5 gives the menu items and how to make changes.
