2.5.4  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 30 seconds, and the system will return to the normal operating mode.

NOTE: CHANGES TAKE PLACE ON GAIN IMMEDIATELY BUT DO NOT GET SAVED UNTIL 
YOU GO TO THE SAVE MENU AND INDICATE YOU WANT TO SAVE THE CHANGES.

Press the Up/Down switch to change the gain in 1 or 10 dB steps and then push the Menu/Execute 
switch to get to the Save Settings Menu:

OUTPUT LEVEL =  -05

R

or by  using  the horizontal rocker switch the cursor can be moved left or right.

GAIN   =             +10

R

Pressing the Up/Down switch down will toggle the display digit selected until you have the desired gain.
 

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.  DO NOT SET A GAIN THAT WOULD EXCEED -5 dBm OR HAVE LESS THAN -25 dBm 
OUTPUT LEVEL. 

When the display indicates the value desired you can push the Menu/Execute switch to the next item OR 
you can scroll to “R”, 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.

Figure 2.4 gives the menu items and how to make changes
