Turn on the SP-II TPU by switching the A/C-D/C switch to A/C for AC operation
or to D/C for DC operation.
The PWR, T/F PWR and LOCK LOSS indicators should illuminate, then after
approximately 45 seconds, the LOCK LOSS indicator should turn off and the
T/F TRIG indicator should begin flashing at the ping rate of the sonar.
6. On the computer, start SonarPro and observe that the towfish is transmitting by
viewing the output pulse in the Sonar Viewer window. Also check that navigation
