(3) Set frequency counter to measure frequency on channel A.
(4) If the frequency counter does not indicate within limits listed in table 3, perform
the alignment procedure in paragraph 13.
(5) Set TI frequency to the next frequency listed in table 3, using the TI key pad and
control knob, and repeat (4) above.
(6) Repeat (2) (c), (4) and (5) above for the remaining frequencies listed in table 3.
