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! The electronic chart in your Humminbird unit 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.

routes, tracks, groups, recordings, etc.) that may occur due to direct or indirect
damage to the unit’s hardware or software. It is important to back up your control
head’s data files periodically. See your control head operations manual for details.
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.
NOTE: The illustrations in this manual may not look the same as your product, but
your unit will function in a similar way.
NOTE: To purchase accessories for your control head, visit our Web site at
humminbird.com or contact Humminbird Technical Support at 1-800-633-1468.
