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 while in
throttle only, but will remain in neutral.

neutral. See the

operation manual for further details.

remains in throttle only mode. You must place the ERC levers into the neutral position to disengage throttle only mode.

2. Press the THROTTLE ONLY button. The button light will turn off.
3. The neutral lights stop flashing and remain illuminated.
1 Lever
The 1 Lever feature enables the ability to command both engines with a single lever on a dual‑engine application. This feature
simplifies engine management during rough sea conditions by allowing you to use a single lever to command both engines
simultaneously. It is not the same as the system feature called Sync.
