| Finish the Installation
1. Hand tighten the split nut onto the threaded transducer stem ONLY until the assembly is firmly
seated, then tighten NO MORE than 1/8 of a turn extra.
WARNING! To avoid damage, do not overtighten the nut.
NOTE: This type of transducer is directional in nature and must be aligned with the front of the
boat (the direction of travel) and parallel to the centerline. Failure to align the transducer properly
will result in incorrect bottom readings and incorrect fish locations. (See the illustrations for
orientation).
2. Remove the excess adhesive sealant from the outside of the hull to ensure smooth water flow
over the transducer.

| Route the Cable
The transducer cable must be routed to the point where the control head is mounted. Your boat may
have a pre-existing wiring channel or conduit that you can use for the routing.
1. Route and secure the transducer cable connector to the control head, avoiding areas where it
may be damaged or interfere with normal boating operations.
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable
insulation. Route the cable as far as possible from any VHF radio antenna cables or
tachometer cables to reduce the possibility of interference. If the cable is too short, extension
cables are available to extend the transducer cable up to a total of 50' (15 m). For assistance,
contact Humminbird Technical Support for more information.
CAUTION! Do NOT mount the cables where the connectors could be submerged in water or
flooded. If cables are installed in a splash-prone area, it may be helpful to apply dielectric
grease to the inside of the connectors to prevent corrosion. Dielectric grease can be
purchased separately from a general hardware or automotive store.

| Connect the Cable
1. Connect the transducer cable connector to the sonar port on the control head or cable tray (if
applicable). See your control head installation guide for details.
The ports are labeled and the connectors are keyed to prevent incorrect installation, so do not
force the connector into the wrong port.
2. The control head will automatically detect the transducer and configure it with the control
head. For additional configuration information, see your control head operations manual.
