Do not attempt to repair the Pro Flasher yourself. There are no user serviceable parts inside, and special tools and techniques are required for reassembly to ensure the waterproof integrity of the housing. Repairs should be performed only by authorized Humminbird technicians. Many requests for repair received by Humminbird involve units that do not actually need repair. If you have trouble with your Pro Flasher, consult the following troubleshooting guide before contacting Humminbird.

1. Nothing happens when I turn the unit on.

Check the power cable connection and fuse. Be sure the power cable is properly connected - red lead to 12 VDC positive, black lead to negative. Often a fuse can appear to be good when in fact it is not. Check the fuse with a tester, or replace it if in doubt.

Ensure that the Pro Flasher unit is fully seated on the mount, and the latch is engaged. The electrical connections to the unit are not made until the unit is securely seated.

2. There multiple flashes at regular intervals.

Check the Sensitivity control, if the control is on maximum sensitivity turn the control counterclockwise until you get an accurate reading.

3. Unusual or no readings are occurring.

The signal that is reflected back to the transducer from the bottom, or fish, must be strong enough to produce a good clear flash on the dial. Weak flashes or no flashes indicates one of the following:

-The Sensitivity control is turned too far counter

clockwise.

-You are positioned above deep decayed vegeta

tion such trees or kelp.

-You are in water over 120 feet deep.

To Correct this problem adjust the Sensitivity control, moving it clockwise toward the maximum setting.

4. I get gaps in the reading at high speeds.

Your transducer requires adjustment. If the transducer is transom mounted, there are two adjustments available to you - height, and running angle. Make small adjustments and run the boat at high speed to determine the effect. It may take several tries to optimize high speed operation.

5. The bottom reading disappears during a hard turn.

This is normal as the transducer comes out of the water, and will correct itself when the turn is complete.

6. My unit loses power at high speeds.

Your Humminbird Wide unit has an over-voltage protection which turns the unit off when input voltage exceeds 17 volts DC. Some outboard motors do not effectively regulate output voltage
