WARNING! This electronic chart is an aid to navigation designed to facilitate the use of
authorized government charts, not to replace them. Only official government charts and
notices to mariners contain all of the current information needed for the safety of
navigation, and the captain is responsible for their prudent use.
WARNING! This device should not be used as a navigational aid to prevent collision,
grounding, boat damage, or personal injury. When the boat is moving, water depth may
change too quickly to allow time for you to react. Always operate the boat at very slow
speeds if you suspect shallow water or submerged objects.
WARNING! Disassembly and repair of this electronic unit should only be performed by
authorized service personnel. Any modification of the serial number or attempt to repair
the original equipment or accessories by unauthorized individuals will void the warranty.
WARNING! This product contains chemicals known to the State of California to cause
cancer and/or reproductive harm.
WARNING! Do not travel at high speed with the unit cover installed. Remove the unit
cover before traveling at speeds above 20 mph.
NOTE: Some features discussed in this manual require a separate purchase, and some
features are only available on international models. Every effort has been made to clearly
identify those features. Please read the manual carefully in order to understand the full
capabilities of your model.
