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.
