My Humminbird Fishin' Buddy will not turn on. What should I check?
These products requires six "AA" size alkaline batteries for operation.
These batteries are not included. Make sure that all six batteries are
installed by removing the battery pack and filling both sides with three
batteries on each side of the pack. If replacing batteries, make sure
all six batteries are replaced at the same time. Only partially
replacing the batteries could also cause a no power situation. These products should NEVER be powered by a 12 volt source. Doing so will
damage your unit and it will need to be returned for service. This
would not be covered under warranty.
