A:Answer Hi Chas! To switch between the different channels on the same station (69-1, 69-2, 69-3), you would typically need to enter the main station number (69) and then use the dash or minus button to access the different sub-channels. Some remotes may also have a dedicated button for sub-channels.
As for using the plus button, it may not be necessary in this case since you are trying to access specific sub-channels within the same station.
As for the Previous Channel button, it is a common feature on many remotes and can be used to quickly switch between the current and previous channel you were watching. Just press the Previous Channel button to toggle between the two channels.
