RADIO SHACK SCANNER PRO-2052 The following is the names and functions for the keys on the front of the unit. Some keys have more than one function; therefore, in such cases, the two functions for that button will be inclosed in parenthesis. On the extreme left, there are two rotary knobs, one above the other; the top is off/on and volume. The bottom one is squelch. Moving to the right, please find two rows of six push buttons: Row one from left to right (remote - hold) (priority - speed) search SVC manual trunk ROW TWO Limit (alert - data) (L/O - skip) delay shift scan On the far right, please find like a touch tone pad: TOP ROW 1 2 3 ROW TWO 4 5 6 THIRD ROW 7 8 9 LAST ROW (clear - decimal) 0 enter Also on the number buttons, beginning with the 1, above it is 11, 12 above 2, 13 above 3, and so on with 19 being above the 9 and 20 above the 0. I hope this information will be of some help to us all! Lowell W8QIY
