Z-RAY BASE STATION SELECTION (BASE ST)
In most instances Z-RAY instantly connects to the only nearby STATION-X, and there is no need to use this setting.
(You can make a note of the displayed STATION-X ID number e.g. 454C 4553 - as your STATION-X will always have the same ID forever. If you have more than 1 Station-X then you may like to label each of them with this ID)
When you horizontally-scroll through base-stations - your Z-RAY does a complete fresh scan for all possible STATION-X's - and refreshes and re-orders the list.
Ensure that you repeatedly scroll to see every available STATION-X.
