2. Ascent (Mode 1). Same as Decent. 



3. Wave Measurements (Mode 3) 



a. Operate in Mode 1 until optimum heading and depth' are reached, 



b. Make a note of sea and ship heading. 



c. Switch off all channels on scanner except Channel 6. Switch 

 scanner display control to manual and counter display control to minimum . 



d. Change coupler manual data to new format indicator (35). See 

 Appendix A, 



*Best depth to conduct wave observation must be determined. It will be a compromise 

 between decreasing EDO performance at greater depths and increasing ship motions at 

 shallow depths. During this operation submarine heading should be such as to reduce 

 roll (either into seas or with seas following).
