Hello I am looking for a visual online course on how to use my new Wisdom 4 dive computer. I downloaded the operator manual to read but find it a bit confusing to navigate. I downloaded the divelog+ app. to blue tooth to, but coudnt figure out how to turn the bluetooth on the computer itself from the innstuction manual. I think it would be very helpful to watch an instructional video or E-class on this particular model. I went to U tube but could not find any . Any leads on how to learn this computer are appreciated. thank you.
