Procedure
Engage Throttle Only Mode
1. Ensure ERC levers are in neutral (prerequisite before pressing button). 2. Press the THROTTLE ONLY button. The button light will turn on and the neutral lights will blink. 3. Place either ERC lever into gear. The warning horn will beep each time the levers are moved in and out of gear, but the engine will remain in neutral. 4. Increase RPM of the engines as needed. WARNING: Pressing the THROTTLE ONLY button while ERC levers are NOT in neutral turns the button light off but remains in throttle only mode. ERC levers must be placed in neutral to disengage throttle only mode.
