Mounting The Transducer - Garmin FishFinder 340C Owner's Manual

Mounting the Transducer

Proper transducer installation is key to getting the best performance
from your new Fishfinder. If the transducer lead is too short,
extension cables are available from your Garmin dealer. Coil and
secure any excess cable. DO NOT cut the transducer lead or any
part of the transducer cable, because this voids your warranty. The
cable cannot be spliced and connected to any existing (Garmin or
non-Garmin) transducer cables.
Following are some tips and basic installation instructions for some
popular transducers. Detailed installation instructions are provided
in the transducer kits. Some transducers might have to be installed
by a professional marine installer.

Assembling the Transducer
To assemble the transducer:
1. Insert the rubber washer and plastic spacer into the
transducer at the same time. DO NOT lubricate the rubber
washer.
2. Route the cable toward the back of the transducer. Slide the
transducer into the transducer mount.
3. Place a 5 mm flat washer on the 10-32 x 1.75" screw, and
insert the screw through the transducer mount, spacer, and
rubber washer.
4. Place the remaining 5 mm flat washer on the exposed
end. Install the 10-32 lock nut tight. You can tighten the
transducer further after installation on the boat.
