Procedure Steps/Notes<br />

Enter satellite<br />

ephemeris data<br />

keys<br />

Load orderwire<br />

keys<br />

Change to DAMA<br />

preset and enter<br />

DAMA network<br />

Not required<br />

Note: This information is obtained from the unit frequency manager (who gets it<br />

from the SMC). It is required only if terminal is set up for silent, passive<br />

mode.<br />

There are eight positions to input satellite ephemeris data.<br />

This information changes. Information used for one exercise may differ for<br />

the next exercise.<br />

1. Change mode selector switch to CT.<br />

2. Scroll to database options and enter (press 2).<br />

3. Scroll to COMSEC key states and enter (press 7).<br />

4. Scroll through key positions to ensure key was filled. Update column should<br />

state 0, unless some of the keys were updated.<br />

1. Change mode selector switch to F2 position. Before loading orderwire keys, it<br />

is best to have the COMSEC keys already loaded. Key positions 1 through 8 are<br />

available. Orderwire keys need to be put in positions 1 to 4 only.<br />

2. Positions 5 to 8 are reserved for over-the-air rekeying in the future.<br />

The only way to check to see if keys were loaded is to go to F2 and see if the<br />

numbers are on the line.<br />

1. Go to current mode screen.<br />

2. Change mode to DAMA.<br />

3. Press preset number for channel and enter (press 2).<br />

4. Ensure all information is correct from preset by pressing enter through all fields.<br />

(The TEK is not part of the presets so special attention should be given to this field<br />

to ensure it is correct.)<br />

5. Press enter on start DAMA (radio does not change to DAMA mode until enter<br />

on network is done).<br />

Notes Watch screen for 5-kHz ACQUIRING; 5-kHz RANGE; 5-kHz LOGIN PND.<br />

If the radio does not go to 5-kHz LOGIN PND or an M is on the net<br />

acquiring line, check the following:<br />

Adjust antenna.<br />

Adjust output power.<br />

Refill keys.<br />

Ensure the proper key is loaded and in correct position.<br />

Radio automatically log in—check for status messages.<br />

Respond and view as necessary to all status messages received.<br />
