It's been a long time since I've looked at one of those tuners; but, I think the row of "bar graph" adjustments is for setting the UHF (ch 14-83) channels. You probably won't need to fool with these adjustments unless you have one, or more, low power analog UHF stations in your area. The UHF positions on the dial should have letters A thru H on the dial. First, you set the AFT to off. Then, advance the tuner to the A position. Next, rotate the knob that corresponds to position A until you tune in the desired UHF channel (for example, channel 17). When these sets were new, they came with a sheet of channel tabs and once the channels were set, the owner could remove the letter tabs and replace them with whatever channel number that corresponds to whatever channel is tuned to that position. Once the "A" position is tuned, advance the tuner to the "B" position and repeat the procedure. The VHF channels (2-13) are programmed in the same way. Just set the tuner to channel 2 and then adjust the corresponding knob for channel 2 until the best picture appears for channel 2. Then, advance the tuner to 3 and do the same thing for the channel 3 position. Once you have all the channels set, return the AFT switch to the ON position.

Those tuners have a means for setting them to skip unused/unwanted channels; but, for the life of me, I can't remember how it's done on this set. I'm sure someone knows and will chime in.
