service. In conjunction with the failed indication will be a code which indicates to the repair personnel where the problem is.
Press MENU to advance to the second Diagnostic screen.
The second Diagnostic screen evaluates external connections to the unit. The first category is Transducer input. If a transducer is detected, a message will indicate "connected".
This is an excellent way to confirm transducer connection. If a transducer is connected directly to the unit, the connection will be indicated here. If a switch is used, use Diagnostic to confirm the connections from each transducer. If a series of dashed lines is shown, then no transducer is connected or there is a problem with the transducer or cable.
The next categories indicate the connection of boat speed sensor and surface water temperature sensor. These accessory sensors can be purchased independently or together as a single sensor (see Available Accessories). If the sensors are connected and working properly, a "connected" message will appear.
Note: This feature only works when the boat is in motion as the paddle wheel on the speed sensor must rotate to be detected.
The voltage input category is especially helpful in diagnosing input voltage problems. The current input voltage will be displayed. If voltage fluctuations or power supply in excess of 16 VDC or less than 10 VDC is suspected, use the diagnostic screen to confirm input voltage. Often, small outboard motors do not effectively regulate voltage when operated at high engine speeds. Use Diagnostic while running the boat at high speeds to show the voltage gain. Also, if you are using the ProAngler in portable configuration or from the trolling motor battery, Diagnostic can be used to evaluate the health of the battery by showing the current voltage.
The total time category indicates the total time the unit has been in use since shipped from the factory.
Note: It is normal for some hours to be indicated in the total time when the unit is new due to factory testing.
While this is often of interest to the user, it is primarily a diagnostic tool for the repair technician should service be required. Press MENU again to exit Diagnostic.
