Connect The Cable; Test And Finish The Installation - Humminbird APEX Series Installation Manual

TRANSOM TRANSDUCER Installation Guide
Δ The transducer can pivot up to 90 degrees in the bracket. Allow enough slack in the cable for
this movement.
Δ If you drill any holes, fill them with marine-grade silicone sealant.
Δ Excess Cable: If there is excess cable that needs to be gathered at one location, dress the
cable routed from both directions so that a single loop is left extending from the storage
location. Doubling the cable up from this point, form the cable into a coil. Storing excess cable
using this method can reduce electronic interference.
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'. For
assistance, contact Humminbird® Technical Support.
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 to the transducer port on the control head or cable connector
(if applicable).
The connector is keyed to prevent reversed installation, and insertion should be easy. Do not
force the connectors into the ports.
If the cable connector is round, hand-tighten the screw nut to secure the cable connection.
Hand-tighten only!
Refer to your control head installation guide for additional details.

| Test and Finish the Installation

Once you have installed the control head, the transducer, and have routed all the cables, you must
perform a final test before locking the transducer in place.
Testing should be performed with the boat in water deeper than 2 feet. The transducer should be
fully submerged because the sonar signal cannot pass through air.
WARNING! The transducer must be fully submerged in water during operation because the sonar
signal cannot pass through air. Air pinging can damage the transducer.
Test the Transducer Installation on the Control Head
1. Press the POWER key to turn on the control head.
If the transducer is detected, the control head will start Normal mode.
2. Select a Sonar View to display on-screen.
HELIX®: Press and hold the VIEW key. Select Sonar > Sonar View.
SOLIX®: Press the HOME key. Select a 2D Sonar View.
Other: See your control head operations manual.
3. If the bottom is visible on-screen with a digital depth readout, the unit is working properly.
4. 2D Sonar Test: If the unit is working properly, gradually increase the boat speed to test high-
speed performance.
5. Review the sonar returns displayed on the (2D) Sonar View. If the unit functions well at low
speeds, but begins to skip or miss the bottom at higher speeds, the transducer requires
adjustment.
