Procedure
Activate One-Lever Mode (Multiple Outboard Motors)
1. Ensure all remote control levers are in the NEUTRAL position. 2. Press and hold the [+] switch while all remote control levers are in NEUTRAL. 3. Confirm activation: a long buzz sounds once and the SYNC indicator comes on. The mode is now in one-lever mode, allowing a single remote control lever to shift gear and adjust engine speed for all outboard motors.
