Power up: Each gauge will power up when the ignition is turned
on. The gauges will stay on as long as the ignition is on.
Lights: Adjusts the brightness and contrast of the gauge.
Buttons: The "MODE/SELECT" button is used for selecting
information screens. The "+" and "-" buttons are used for setting
engine speed during troll, cruise control, and setting gauge
calibrations.
Troll Control: Sets and controls the idle speed of the engine for
trolling without using the throttle. (System Tachometer and
Speedometer).
Cruise Control: Sets and controls the speed of the engine for
cruising. (Smart Tow Tachometer only).
Launch Control: Sets and controls the speed of acceleration from
idle to set cruise speed. (Smart Tow Tachometer only).
Engine Guardian System: Monitors the critical sensors on the
engine for any early indications of problems. The system will
respond to a problem by reducing engine speed and alert the
operator to a potentially damaging situation.
Warning System: The system sounds the warning horn and
displays the warning message.
Master Reset
Returns the gauge to the factory defaults through the Master Reset
command.

BASIC OPERATION AND FEATURES

IMPORTANT: Performing a master reset will reset the unit to the
factory defaults, thus eliminating any installation and calibrations
performed during set up of product.
Press the "-" and "+" buttons simultaneously for approximately 10
seconds (until the graphic bars collide) to restore the unit to factory
default settings. Press the "MODE/SELECT" button to confirm.

Auto Detection Engine Function
The System Tachometer/Speedometer and Smart Tow
Tachometer come standard with an Engine Auto-detection feature.
This feature lets the gauge, on the initial power up, automatically
detect which engine type is used and configure the gauge to match
that engine type.
On first time power up of the gauge or after a Master Reset, the
gauge will display "AUTODETECT". Upon pressing the "MODE/
SELECT" button, the gauge will automatically determine engine
type. This will preset the data monitoring screens accordingly. The
intention is to make initial setup easier. Press the "MODE/
SELECT" button to start the Auto Detection Engine function.

If the gauge shows a warning of "NO STARBOARD ENGINE" or
"MULTIPLE STARBOARD ENGINES", the engine location must
be properly selected (Port and Starboard) at the engine using a
Mercury Computer Diagnostic System tool (CDS). Perform the
Master Reset and Auto Detect functions again. (Refer to Master
Reset).

When a problem is detected, the name of the offending alarm
appears on the display.
If problem can cause immediate engine damage, the Engine
Guardian System will respond to the problem by limiting engine
power. Immediately reduce the throttle speed and refer to the
warning messages on the following pages. Refer to the Engine
Operation, Maintenance, and Warranty Manual for further
explanation of the problem and the correct action to take.
The alarm message will stay displayed until the "MODE" button is
pressed. If there are multiple alarms, these will cycle on the display
at five-second intervals.
If the "MODE" button is pressed to display a different screen, the
flashing alarm signal "AL" will appear in the upper right corner to
indicate there still is a problem.

14.NO STARBOARD ENGINE: The instrument does not detect
the starboard engine computer. This usually indicates that no
data is being transferred from the engine's computer to the
gauge. Check the wiring. Make sure both terminator resistors
are installed in the bus. Make sure both ECMs are not
configured for the port location using a DDT or Quicksilver
Diagnostic Tool.
15.MULTIPLE STARBOARD ENGINE: SmartCraft gauges are
recognizing multiple engines as starboard.
NOTE: In multiple engine applications, each engine must first be
assigned a position (starboard, port, starboard2 or port2) with a
Computer Diagnostic Tool (CDS) before the system will function
properly.
16.OIL TEMPERATURE: The engine oil is overheating.
