User manual HUMMINBIRD XBTH 9 QB90T

[. . . ] When the boat is moving, water 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. 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. [. . . ] Testing the Transducer Prior to Installation Prior to installation, test the transducer to make sure that no damage occurred during shipping. After connecting the transducer to the fishfinder, hold the transducer in the water over the side of the boat to confirm proper operation. If the transducer is working properly, you should be able to see the bottom on the control head display. The bottom image should be relatively strong and there should be detailed structure on the display. Rivets Transom Strakes Hull Preferred Mounting Location 2. Locating the Transducer Mounting Position Outside the boat, the best location for the transducer will be aft midship, as close to the centerline of the boat as possible. The transducer should be mounted forward of the propellers on inboard boats, and separated adequately from other transducers, strakes, rivet lines, or other protrusions. Make sure that there is nothing in front, behind, or to the side of the transducer that is closer than 12". Inside the boat, there must be room to access the mounting location for installation and cable routing. © 2008 Humminbird®, Eufaula AL, USA. All rights reserved. 2 Bronze Thru-Hull Transducer Deadrise: Another consideration is the angle of deadrise. If the selected mounting location has a hull deadrise of 8 degrees or greater, a leveling block should be used to level the transducer housing and direct the sonar signal straight down. If you need to use the leveling block, make sure that the inside surface of the hull is smooth enough to seat the leveling block securely. NOTE: If the included transducer will not work for your application, you may exchange it, NEW and UNASSEMBLED, with mounting hardware included, for a transducer appropriate for your application - often at very little or no charge depending on the transducer.

Apply a generous amount of marine-grade silicone sealant or slow-curing epoxy inside the drilled hole and along the mating surfaces of the transducer housing. Insert the transducer into the drilled hole from outside the boat, then install the nut onto the threaded stem from inside the boat. NOTE: If you are using a leveling block outside the hull (to correct for deadrise), you must use a similar block inside the hull to provide a level bearing surface. 530513-2_C 4 Bronze Thru-Hull Transducer Maintenance If your boat remains in the water for long periods of time, algae and other marine growth can reduce the effectiveness of the transducer. If your boat remains out of the water for a long period of time, it may take some time to wet the transducer after it is returned to the water. Small air bubbles can cling to the surface of the transducer and interfere with proper operation. These bubbles will dissipate with time, or you may wipe the face of the transducer with your fingers after the transducer is in the water. 530513-2_C Attaching the Transducer Humminbird® Service Policy Even though you'll probably never need to take advantage of our incredible service policy, it's good to know that we back our products this confidently. We will make every effort to repair your unit within three business days from the receipt of your unit at our factory. Units received on Friday are typically shipped by the following Wednesday, units received Monday are typically shipped by Thursday, etc. All repair work is performed by factory-trained technicians to meet exacting factory specifications. Factory-serviced units go through the same rigorous testing and quality control inspections as new production units. After the original warranty period, a standard flat rate service charge will be assessed for each repair (physical damage and missing parts are not included). [. . . ] The thinnest wall of the outside level block must be at least 1/8". NOTE: A separately-purchased fairing block can also be used to create a hydrodynamic waterflow around the transducer body. The design and fabrication of this block varies greatly with different hull shapes; therefore, it should be customized by a qualified marine technician. Transducer Housing 5. Connecting the Cable Insert the transducer cable into the appropriate terminal slot. The cable connectors are labeled, and there are corresponding labels on the cable holder on the rear of the fishfinder. [. . . ]
