Speed Range 

The Speed Range function is included in the System Setup menus of 

the following pages: Synchronizer, Single Analog, Dual Analog and 

Quad Analog. The Speed Range feature can make on-screen gauges 

easier to read by allowing you to choose a range that will better fit your 

vessel’s speed capabilities. If, for example, your vessel's speed range is 

0-40, the unnecessary figures (41-120) will only crowd the gauge 

display, making it harder to read. Using the Speed Range feature 

allows you to eliminate unnecessary figures from the display, giving it 

better resolution.  The default speed range is 0-40 mph.
