my 947 c says transducer not connected

When powering on, if a message indicates "transducernot connected", ensure that an appropriate transducer connector is plugged intothe unit. Second, inspect the transducer cable from end to end for breaks,kinks, or cuts in the outer casing of the cable. Also ensure the transducer isfully submerged in water. If the transducer is connected to the unit through aswitch, temporarily connect it directly to the unit and try again. If none ofthese items identifies an obvious problem, the transducer itself is probablythe problem. You need to replace it. Another thing is - a lowvoltage condition would cause the unit to not recognize the transducer. Youneed to check it also. Hope this will help you.

Hi,

You have to connect or install a transducer. I will help you to connect it.

First, determine the best location on the transom to install the transducer.

The transducer cable has a low profile connector that must be routed to the point where the control head is mounted. There are several ways to route the transducer cable to the area where the control head will be installed. The most common procedure routes the cable through the transom into the boat.

Unplug the other end of the transducer cable from the control head. Make sure that the cable is long enough to accommodate the planned route by running the cable over the transom.

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).

If you will be routing the cable through a hole in the transom, drill a 5/8" diameter (16 mm) hole above the waterline. Route the cable through this hole, then fill the hole with marine-grade silicone sealant and proceed to the next step immediately. Place the escutcheon plate over the cable hole and use it as a guide to mark the two escutcheon plate mounting holes. Remove the plate, drill two 9/64" (3.6 mm) holes, and then fill both holes with marine-grade silicone sealant. Place the escutcheon plate over the cable hole and attach with two #8 x 5/8" (16 mm) wood screws.

Route and secure the cable by attaching the cable clamp to the transom; drill one 9/64" dia. (3.5 mm) x 5/8" deep (16 mm) hole, then fill hole with marine grade silicone sealant, then attach the cable clamp using a #8 x 5/8" (16 mm) screw.
Plug the other end of the transducer cable back into the control head connection holder

Hi!
Please go into the menu and select the 'Nav' tab then choose the 'Chart Orientation' setting and set to 'North - Up', also make sure 'North Reference' is set to 'True'.
If that doesn't work, reset the sounder back to factory defaults and try again.
Here's the manual to you sounder:

I've got the 565 and everything will be working fine and then the depth finder or bottom of the lake goes to 6ft. Have to shut it off for an hour and it works for a wile but it always goes back to doing it anything I can do? Thanks Jeff
