| Lock Down the Transducer (Optional)
NOTE: You have the option to lock down the Two Piece Kick Up bracket if you do not want the
transducer to kick up. Please be aware, however, that the transducer can be damaged if it is locked
down and it strikes debris in the water.
1. To lock down the transducer, trace the position of the mounting bracket. Force the pivot to
the Up position to gain access to the mounting screws, then re-align the mounting bracket
against the transom of the boat to match the traced silhouette. Check the bracket position
with the level again to make sure it is still level, then mark the fourth mounting hole using a
pencil or marker (see Using the Mounting Bracket to Mark the Initial Drill Holes). Unscrew and
remove the mounting screws and the transducer assembly and set aside.
2. Drill the fourth mounting hole, using a 9/64" drill bit. Use a marine-grade silicone sealant to fill
all four drilled mounting holes, especially if the holes penetrate the transom wall.
3. Re-position the transducer assembly against the transom of the boat, then hand install the
first three screws (two on the outside edges and one in the 3rd mounting hole). Make sure
that the transducer location and the pivot angle have not changed, then fully tighten all three
mounting screws (see Fully Tightening All Three Mounting Screws). Hand-tighten only!
4. Snap the pivot back down. Install the #8 x 1" wood screw into the 4th hole to lock down the
pivot arm. Hand-tighten only!
Setting Up an Accessory Transducer on the Control Head
The control head will automatically select the transducer that was included with your control head.
If a compatible accessory transducer is connected, you will need to set the transducer type on the
control head. When you select the transducer type, the related views and menus will be added to
the system.
Δ For additional configuration information, download the control head operations manual from
our Web site at humminbird.com.
