2.3 Basic Operation
2.3.1 Normal Operating Mode
A The Control Head has three detents; Ahead, Astern and Neutral.
B With the Control Head lever positioned in the Neutral (vertical) detent, the Processor will
command Neutral and the throttle at Idle revolutions per minute (RPM).
C Movement of the Control Head’s lever 15 degrees to the Ahead or Astern detent will
command Ahead or Astern clutch engagement, while the engine RPM remains at Idle.
D Further movement of the Control Head lever through the next 65 degrees, will increase the
engine RPM in proportion to the Control Head’s lever position.

2.3.2 Trolling Valve Operation
The operation is quite different in Systems equipped with Trolling Valves. Troll Mode is a feature that
must be turned On and Off at the Control Head. On initial power-up, Troll Mode is disabled.
A The Control Head has three detents; Ahead, Astern and Neutral. To turn ON Troll Mode, place
the Control Head lever in any of the above mentioned detents.
• With the Control Head lever positioned in the Neutral (vertical) detent, the Processor will
command Neutral, the trolling valve will be at lock-up and the throttle at Idle rpm.
B Depress and hold the transfer button for two (2) seconds.
• The solid red indicator light on the Control Head will begin blinking rapidly, indicating the
system is now in Troll Mode.
C Once the system has been placed in Troll Mode, movement of the Control Head’s lever 15
degrees to the Ahead or Astern detent will command Ahead or Astern clutch engagement
and the trolling valve commanded to minimum pressure, while the engine RPM remains at
Idle.
WARNING: Personal Injury may result if this message is disregarded.
NOTE: If system is set for Twin Screw operation, ensure all Control Head levers are in the same detent
(Neutral, Ahead or Astern).
