Control Handle - Operation of the shift and throttle are controlled by the movement of the
control handle. Push the control handle forward from neutral with a quick, firm motion to
the first detent for forward gear. Continue pushing forward to increase speed. Pull the
control handle back from neutral with a quick, firm motion to the first detent for reverse gear
and continue pushing back to increase speed.
Active Light - The active light is illuminated to show the remote control is active and ready
for use.
Neutral Light - The neutral light is illuminated when the engine is in neutral gear position.
Select Key - Selects System View on‑screen options and confirms data entries.
Arrow Trackpad - Navigates through System View on‑screen function messages.
Sync Light - The sync light is illuminated when the RPM of the two engines are being
synchronized by the DTS system.
Throttle Only/Station Select Key - Allows engine throttle advancement without shifting
the engine. The throttle only/station select button also allows the boat operator to select
which remote control is in control of the engine operation when operating with multiple
helms. Refer to Dual Helm Station Transfer.
Detent Tension Adjustment Screw - This screw can be adjusted to increase or decrease
the effort required to move the control handle out of the detent positions (cover must be
removed). Turning the screw clockwise will increase tension.
Control Handle Friction Adjustment Screw - This screw can be adjusted to increase or
decrease the tension on the control handle (cover must be removed). This will help prevent
unwanted motion of the handle in rough water. Turn the screw clockwise to increase
tension and counterclockwise to decrease tension.

Synchronizing Dual Engines

The auto synchronizing feature, when engaged, will automatically adjust the port engine
speed to match the speed of the starboard engine.
Synchronizing of engines will automatically engage when the speed of both engines are
over 900 RPM for two seconds and remote control handles are positioned within 5° of each
other.
