i have just tuned a kv-m 2141, if its the same then you have to hold the shift (red up arrow) and the preset (red left arrow into diamond box. This should bring the uhf bar up.
now hold shift and press the +/- buttons to tune. NB not the prog +/- buttons , there is another set to the left?
Press shift and preset again to exit and store. repeat for channels 2-5 or whatever. you can download a manual for this for ten bucks at manuals paradise for more info, or i could forward you the file
