Sorry for any delayed response.
OK - let's start by getting you a link to the electronic (PDF) version of the manual, which includes how to INSTALL the device & transducer, and how to operate it. This manual covers a few models, including the 196ci.
Click the link below to DOWNLOAD the manual to your computer. Make sure you make note of where it downloads to, as you will want to go to that folder and double-click on that file to open it.
Also, MOST computers & devices have a built-in PDF "viewer", so when you double-click on the file on your computer, it will open with that viewer. But if you don't have that, below is a link to where you can get a no-cost viewer program. Just make sure you UN-check any "optional offers" BEFORE you click the Install Now button.
Let me know if you have any issues downloading and viewing that manual. Once you do, please review the basics for installing and using the device (and transducer), and then let me know if you have any more SPECIFIC questions about its operation and what does or does not work, and then we can continue with the next steps - if needed.
Thanks, ***** *****
