ECM:  The Electronic Countermeasures feature allows you to deploy certain 
equipment methods that deflect the enemy's weapons from your ship. ECM is 
always on automatic mode (hence the red color for "On") and set at a 
default of 12 nautical miles. This is where the ECM is automatically set 
to deploy whatever countermeasures you want to use. You can increase the 
range by clicking on the range number with the right mouse button or 
pressing lower case "e". Decrease the range by clicking on the range 
number with the left mouse button or pressing upper case "E". To toggle 
ECM between automatic and manual modes, press upper case "F". To select 
manual ECM deployment directly, press lower case "d". If you choose to 
turn off the ECM, you must manually turn it off by clicking on "ECM"; it 
will turn green to signify that it has been turned off. The various 
deployment methods are listed to the right of ECM by letters and are 
toggles:

     C:  Chaff (5)
     R:  Radar jamming (6)
     F:  Flares (7)
     I:  Infrared (IR) jamming (8)
     D:  Decoys (9)
