Hope you are all well. I have a question related to a Raymarine bi-data unit.
It was already fitted on the boat and as such it was the one handbook that was not supplied when I purchased the boat (secondhand). It has 3 buttons
One with an arrow up
One with an arrow down
One with a dot on it
Anyway, I have been able to scroll using the up/down arrows. However I donít know how to change any data, e.g. min depth of water. I have tried all sorts of permutations but to no avail. Does someone know how to use before I call Raymarine
