User manual HUMMINBIRD XBTH 9 QB90T

[. . . ] This device should not be used as a navigational aid to prevent collision, grounding, boat damage, or personal injury. 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. [. . . ] 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. © 2008 Humminbird®, Eufaula AL, USA.

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. Seal the mating edges of the leveling block (if using one) as well. 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. Periodically clean the face of the transducer with hot water. 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.

[. . . ] 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. The slots are keyed to prevent reversed installation, so be careful not to force the connector into the holder. Your fishfinder is now ready for operation.
